CREDITS SEQUENCE NEWSPAPER HEADLINE MONTAGE: HEADLINES flash before us, displaying their accompanying photographs. "UBERMAN - METRO CITY'S HERO AFTER DEFEATING MASTER MIND! PHOTO: A chiseled, statuesque man wearing the COOLEST SUPER HERO SUIT IMAGINABLE, COMPLETE WITH FLOWING CAPE, shines a confident smile at the lens. This is UBERMAN, champion of METRO CITY. "UBERMAN DEFEATS MASTER MIND'S GIANT ROBOT!" PHOTO: Wide-shot of Uberman in mid-flight lifting the GIANT ROBOT in the sky above the city buildings. "MASTER MIND ALL WET AFTER UBERMAN FOILS AQUARIUM HEIST!" PHOTO: Uberman stands knee-deep in water. He has his enemy by the collar. The villain blocks his face from the shot with a METALLIC GAUNTLET. The images start to flash by even quicker, each showing the MYSTERIOUS VILLAIN in various stages of humiliation. In each photograph he successfully blocks his face with his armored glove. We ZOOM IN to the last headline. "MASTER MIND BEHIND BARS ONCE AGAIN - THANKS TO UBERMAN!" PHOTO: Uberman stands in a gallant pose with his fists on his hips, obviously trying to accentuate the "U" insignia on his chest. END OF CREDITS SEQUENCE EXT. BUILDING - DAY We DISSOLVE from the photograph to Uberman standing in the exact same position. WE PULL BACK showing him atop a BUILDING overlooking the city below. A perfect view for our guardian hero. He watches the thriving metropolis, bristling with life as people happily go about their day. Yet, we can't help but detect a hint of sadness in Uberman's expression. 2. UBERMAN You look so peaceful from up here. His serenity is suddenly interrupted by a loud BEEPING SOUND coming from his wrist. He looks down at a BRACELET (a manly one) on his right arm. It's a silver band with a FLASHING red letter "U". UBERMAN (CONT'D) Looks like Roxanne's in trouble again. Uberman leaps off the building and into the air. His cape gracefully flows in the breeze behind him as he shoots off into the distance like a speeding bullet. EXT. OBSERVATORY HIDEOUT - ESTABLISHING SHOT Grime and moss decorate the outside of this long abandoned building overlooking the COAST. Once a place of knowledge and wonder - now home to a great evil. INT. OBSERVATORY HIDEOUT - DAY The inside is in complete contrast to the exterior. The huge hall with a GIANT TELESCOPE teems with advanced ELECTRONIC EQUIPMENT. Computers, monitors and machines which do not have an obvious function FLASH and HUM. A STEEL DOOR slides open, revealing the subject of our story MASTER MIND - a villainous sight to behold. His FACE IS INEXPLICABLY LIGHT BLUE, topped by an OVERSIZED, MUSHROOM- SHAPED HEAD with a CIRCULAR PATCH OF WHITE HAIR ON TOP. He's dressed in the kind of costume only a super villain could pull off: a PURPLE JUMPSUIT AND BLACK BOOT ENSEMBLE WITH A GIANT GREEN "M" ON THE CHEST. His right hand, hanging at his side, is a METAL GAUNTLET WITH THREE SHORT SPIKES PROTRUDING BETWEEN HIS KNUCKLES. Master Mind begins to survey the room with his TWO PERMANENTLY ARCHED EYEBROWS. A man dressed as ALBERT EINSTEIN is busy ranting to two other men. One, a hulking brute, is dressed as LEONARDO DA VINCI. The other, a small intellectual-type carrying a clip-board, is dressed as the philosopher PLATO. EINSTEIN I hate the outfits. I mean, I get it: we're all supposed to be "masterminds" - very clever. (MORE) 3. EINSTEIN(cont'd) I just feel stupid. I mean, what the hell did Einstein really do anyway? PLATO Theory of relativity. Einstein starts feverishly scratching his side. EINSTEIN Well, you'd think he'd invent a wool sweater that didn't itch so much. Da Vinci and Plato's eyes suddenly grow with concern as they see Master Mind walk up behind Einstein. Einstein notices his colleague's staring over his right shoulder and turns around. He turns around and Master Mind SEIZES HIM BY HIS THROAT with his metal gauntlet. MASTER MIND The real Einstein once said, "God does not play dice with the world." He was right, because the world is MY dice. Is that understood? DA VINCI & PLATO Sir! Yes, sir! EINSTEIN (gasping for air) Yes, sir. Master Mind undoes his grip on Einstein's throat. MASTER MIND Alright, then - clean slate. Do we have the girl? DA VINCI Yes, sir. She fell into our trap just like you knew she would. MASTER MIND Reporters are a curious lot, and easily manipulated. He quickly checks his physique in a GIANT MIRROR, adjusts his posture and sucks in his gut. 4. MASTER MIND Alright, let's not keep the lady waiting. MOMENTS LATER Da Vinci escorts a BLINDFOLDED and bound woman, ROXANNE RITCHI, to the back of the room where Plato and Einstein are standing guard over a large BLACK SWIVEL-CHAIR facing away from us. She pulls free of Da Vinci's grasp and waits for him to undo the blindfold. Her face uncovered, we finally see Roxanne's striking features - all of which seem overshadowed by piercing eyes that seem more put off by the situation than afraid of it. MASTER MIND (O.S.) Miss Ritchi, we meet again. The chair turns menacingly slow, finally revealing Master Mind. ROXANNE You didn't need to turn around like that. I can recognize the stench of failure. Master Mind unleashes a wicked laugh. MASTER MIND I trust you gentlemen know the very sassy Roxanne Ritchi, highly regarded investigative journalist who some say has a more than friendly relationship with our super powered foe Uberman. And Miss Ritchi, I trust you've already met my new crew: The Mad Geniuses! Roxanne gives Einstein a once over. ROXANNE Looks like a real group of winners. At the risk of sounding cliche', you'll never get away with this. MASTER MIND In a way, I already have. Roxanne unleashes an exhausted SIGH. 5. ROXANNE We go through this every time. You kidnap me to get to Uberman, he immediately finds your hideout, escapes whatever lame trap you've come up with, and takes you and your cronies to jail. I propose we just save everybody some heartache this time by YOU letting me go, and ME forgetting this whole thing ever happened? MASTER MIND What about my revenge? ROXANNE We can say it was wasting everyone's time. MASTER MIND You have a wicked tongue. I hope you rid yourself of that when you're my queen. Roxanne unleashes a snort-filled laugh. ROXANNE I'm sorry. What makes you think I would want to be your queen? MASTER MIND Power corrupts absolutely, Miss Ritchi. And when I have ultimate power over this city, I have absolutely every intention of corrupting you with it. PLATO Sir! Master Mind turns to Plato who's now standing at a computer terminal. MASTER MIND (annoyed) What is it!? EXT. OBSERVATORY HIDEOUT - DAY Uberman flies toward the Observatory like a rocket. 6. INT. OBSERVATORY HIDEOUT - DAY Uberman crashes through the wall to the room we were just in. He looks around, but there's suddenly NOT A SOUL IN SIGHT. CUT TO: EXT. MASTER MIND'S HYDROFOIL - DAY The boat is shooting through the ocean, away from the observatory. INT. HYDROFOIL CONTROL ROOM - DAY Machines, cables and terminals criss-cross the craft's main bridge. Through the enormous surrounding windows we can see the observatory shrinking in the distance. Master Mind watches Uberman on a small TV monitor as the hero intently searches his hideout. UBERMAN (on monitor) Master Mind! INT. OBSERVATORY HIDEOUT - DAY Uberman throws up his arms in frustration when suddenly - MASTER MIND (O.S.) Over here, old friend. He turns to see a FAMILIAR BLUE FACE OF EVIL ON A GIANT SCREEN. UBERMAN What's the matter, miss your old jail cell? Uberman starts walking toward the monitor. MASTER MIND (ON MONITOR) Actually, I wanted to share the experience with my oldest friend. A MECHANIZED CAGE shoots out of the floor, suddenly trapping Metro City's protector. Totally unfazed, our hero stares on. 7. UBERMAN You can't possibly believe this will work. Master Mind pulls out a SMALL BLACK BOX with a SINGLE RED BUTTON on it. MASTER MIND (ON MONITOR) Oh, can't I? I have attained control of the Earth's most abundant energy source. I doubt even you are strong enough to withstand the FULL CONCENTRATED POWER OF THE SUN!!! He presses the button. EXT. OUTER SPACE A sinister-looking SATELLITE orbits Earth's atmosphere. Its bay doors suddenly open, deploying two huge SOLAR PANELS. The panels shift, angling themselves in the direction of the sun. They immediately start GLOWING as they absorb the burning star's power. The front of the satellite begins to make a loud HUMMING SOUND as it prepares to unleash its unholy power. INT. HYDROFOIL CONTROL ROOM - DAY From the giant window we can see the boat is a good mile from the observatory. PLATO We're now at minimum safe distance, master. Master Mind turns from the CAMERA he was broadcasting on and puts down the control box. MASTER MIND Excellent. Stop here, I like this view. PLATO Twenty seconds until impact. Master Mind turns to Roxanne who is being held by Da Vinci and Einstein. She almost appears a little bored. Disappointed by her lack of horror, he walks over to the monitor now showing Uberman trapped in the cage. 8. MASTER MIND Any last words? Uberman looks up at the screen with a cocky smile. UBERMAN (ON MONITOR) Yes: there's no caging the power of justice. PLATO Ten seconds to impact. On the screen we see Uberman take two of the cage's bars in his hands. He yanks...NOTHING. PLATO (CONT'D) Nine... Master Mind stares at the monitor, slightly confused. PLATO (CONT'D) Eight... Uberman yanks on the bars again, this time using his foot as leverage. MASTER MIND (genuinely concerned) What's going on? UBERMAN (straining) Hold...on...a second. Master Mind looks back at Plato and Einstein. They're equally befuddled at the hero's sudden weakness. PLATO Seven... Uberman loses his grip and FALLS BACKWARD ON HIS ASS. UBERMAN SON OF A BITCH!! Master Mind and the minions all cringe in unison. Da Vinci turns to Roxanne not believing his ears. DA VINCI What did he just say? 9. PLATO Six......Five... Master Mind begins to laugh. MASTER MIND What kind of trick is this? Uberman looks up at the camera with a very grave expression. UBERMAN Like you don't know. These bars are made of copper, aren't they? PLATO Four... MASTER MIND Yeah, so? Uberman tries to shield his grief with his hand. UBERMAN You figured out my weakness, damn you. I CAN'T BEND COPPER! PLATO Three... MASTER MIND Your weakness is copper? PLATO Two...one. Everyone turns to the window. EXT. OUTER SPACE The satellite fires a giant BEAM OF LIGHT toward the earth. EXT. OBSERVATORY HIDEOUT - DAY The beam hits the observatory. The building instantly EXPLODES in a white nova blast of fire. INT. HYDROFOIL CONTROL ROOM - DAY The blast is so bright everyone turns away from the window. Then, as suddenly as it began, the awesome light dies out. One by one, the passengers unshield their eyes and look out toward the observatory. 10. All we can see through the haze of destruction is fire and smoke. PLATO I don't think even he could have survived that. Einstein suddenly turns giddy with excitement. EINSTEIN Whoa! Is it me or did you just finally destroy Uberman? MASTER MIND (carefully skeptical) Well...let's not get ahead of ourselves. Da Vinci suddenly sees something outside. DA VINCI Look, there's something in the sky, coming this way. ROXANNE Uberman! Master Mind turns toward the window. An object is in the air, flying directly toward them. As it closes in we can just make out the FAMILIAR OUTLINE OF A CAPPED FIGURE. MASTER MIND I KNEW IT! PREPARE YOURSELVES! HE'S GONNA RAM US!!! Everyone scatters and braces themselves for the impact. Master Mind, seeing all the good places taken, doesn't know what to do with himself. He just covers his giant head with his hands. The figure CRASHES THROUGH THE WINDOW and lands at his feet. He looks down to see a CHARRED BLACK HUMAN SKELETON. Around its neck is the unmistakable black cape of Uberman. MASTER MIND (CONT'D) (horrified) HOLY SHIT! 11. Roxanne breaks out of Da Vinci's hold and runs over to the body. ROXANNE Uberman? She stares down at the still smoking corpse, the tattered black cape with the yellow "U" on it. Roxanne turns to Master Mind, who's still visibly dumbfounded at the grotesque sight before him. ROXANNE (CONT'D) You killed him! Roxanne's eyes roll back. Da Vinci catches her from behind as she FAINTS. Einstein turns to Master Mind, looking at him as if he's just walked on water. EINSTEIN You did it! Now that he's committed the impossible - our villain is at a complete loss. MASTER MIND ...so I did. EINSTEIN I mean, I know you always wanted to. I mean, all the schemes all the plots - I never thought you'd actually be capable of it. Giddy as a school girl, Einstein turns to his fellow henchmen. EINSTEIN This is history. Every villain and lackey in the history of villains and lackeys dream of this moment, but when does it actually EVER happen? A sudden realization comes over his face. EINSTEIN Good lord...You do all realize what we get to do now, don't you? 12. His question is met with acquisitive looks from Master Mind and the others. EINSTEIN We get to go on a crime wave. CRIME WAVE MONTAGE - SET TO "Fun Fun Fun" by The Beach Boys. SPINNING HEADLINE: "UBERMAN'S DEATH IGNITES CITY WIDE CRIME WAVE!" ARMORED TRUCK It's driving along when the men inside suddenly notice something - THEY'RE FLYING HIGH ABOVE THE CITY STREETS. We PULL BACK to see the truck being carried by a giant claw at the bottom of a BRAIN COPTER. Inside the cockpit Master Mind and his henchmen laugh maniacally. SPINNING HEADLINE: "CHAMPION-LESS CITY AT THE MERCY OF HOOLIGANS." METRO CITY BANK Da Vinci and Einstein run out the front of the bank holding BAGS OF MONEY. Two beat officers see them and take chase after them around the corner and into an alley. After a moment the police reemerge from the alley screaming and running for their lives as a GIANT ROBOT CHASES after them. The robot stops, then suddenly it's head opens up like convertible car top with Master Mind and Plato at the driver's wheel. They smile and shake hands at a bad deed well done. SPINNING HEADLINE: "MASTER MIND BLACKMAILS METRO!!!" A VICIOUS TORNADO It's heading for downtown Metro as Master Mind and the lackeys coolly look on. Three large DUMP TRUCKS pull up, filled to the brim with bricks of CASH. 13. The DRIVERS jump out as the lackeys take the driver seats in the three trucks. Master Mind is about to climb into the passenger seat of one when a drivers taps him on the shoulder and motions toward the tornado. MASTER MIND (absentmindedly) Oh, right. Master Mind pulls a television REMOTE from his pocket and aims it at approaching windstorm of death. He presses the button marked "Tornado Off." The tornado shrinks and disappears just before it hits the city. As they drive through the city streets, Master stares out the window with a hint of something in his eyes. Is it melancholy? END OF MONTAGE EXT. KINGPIN BOWLING - DAY It's Metro City's premier bowling alley. On top of the neon lit building is a GIANT 30 FOOT TALL CEMENT BOWLING BALL. INT. KINGPIN BOWLING - DAY HAL STEWART (early 30's) takes careful aim with his BOWLING BALL. HAL It's a sport of honor, focus and grace. Honor the ball, focus on the pins, release the ball not hard and fast, but as if you were releasing a baby dove. He takes a step, pulls back his arm, and releases the ball, following it with his eyes. It's a horrible shot - INSTANT GUTTER BALL. An aged barmaid type with a cigarette hanging from her mouth looks over at him. HAL Okay, do something like that - but center it more. 14. She picks up her custom made FOGHAT BALL and takes aim. ATTRACTIVE BLOND Tell me how my form looks, honey. Hal focuses on the misshapen bumps of her enormous Johnson administration era derriere. HAL Oh, it's lookin' good. It's lookin' REAL good. It doesn't get anymore clear. This man is a pig. VINNIE (O.S.) Hal, I want to see you in my office! Hal turns to see VINNIE, owner of the bowling alley, calling him. VINNIE Now! INT. KINGPIN BOWLING - VINNIE'S OFFICE - MOMENTS LATER Hal sits down, facing Vinnie who's sitting at his desk. VINNIE You're fired. Leave your shirt and locker key. This bit of news hits Hal like a freight train. HAL Fired? Are you going to tell me why? VINNIE Showing up to work late. Showing up to work late drunk. Sexually harassing customers. Stealing from the register. HAL Vinnie, I don't know where you're getting these accusations - Vinnie takes out a video tape from his desk drawer and puts in a VCR. 15. HAL Oh, which one do you supposedly have here? VINNIE This is all of them at once. TELEVISION A WOMAN walks up to a BOWLING EMPLOYEE and hands him a pair of shoes. As the employee turns to the wall of shoes, a very drunk and disheveled Hal comes running in and pushes him aside. HAL I've got this one, Benny. So, Cinderella. Can I help you find your glass slipper? WOMAN Yeah, I'm looking for a seven. He folds his arms on the counter and leans into her with a cat-like grin on his face. HAL (with a leer) Seven - Well, maybe I could interest you in something in an EIGHT. Namely, me. Disgusted, she walks off screen. HAL Lesbo. Suddenly realizing the register's open, he quickly grabs a stack of cash and shoves it in his pocket. BACK TO OFFICE Vinnie turns off the television and waits for Hal to respond. HAL From the angle of the camera, I can see where you might have gotten the wrong idea. Listen, Vinnie, I don't think you've thought this through. If you fire me, who's gonna be captain of the alley's bowling team? 16. VINNIE Um, I don't know. Maybe somebody who can actually bowl. You guys have never won a game. I hired you because you said you were on the pro circuit. HAL No, I said I WILL BE on the pro circuit. VINNIE Please, a loser like you will never amount to anything. This harsh remark seems to leave Hal genuinely stunned. HAL Wow...If that's how you feel...I guess we should then talk about what kind of severance I'm gonna get. EXT. KINGPIN BOWLING - DAY TWO BRUISERS open the door and throw Hal out onto the street. He quickly picks himself up and turns back toward the building. HAL Hey...what about my ball? A bowling ball sails past him, just missing his head. HAL Thank-you! EXT. CHANNEL 7 NEWS BUILDING - DAY The massive building with a giant 7 on the roof stands in the heart of Metro City. INT. CHANNEL 7 NEWS BUILDING - OFFICE - DAY The cubicles and offices are alive with the hustle and bustle of a busy news day. Phones are RINGING, REPORTERS are TALKING, and Editors are SHOUTING. The elevator doors open and out steps Roxanne Ritchi. 17. Everything stops as the entire office suddenly falls SILENT. Somewhat taken aback by the reaction, Roxanne scans the room to see every eye on her. ROXANNE It's...um...It's good to be back. Thanks for everyone's cards and concerns. I really appreciated it - now I'm ready to climb back on the horse. No one is budging - their looks of pity are really starting to make her uncomfortable. The back office door suddenly opens and out comes FRANK BONIN, the gruff, middle-aged Producer of Channel 7 News. Noticing the silence, he looks up and sees the sad expressions on everybody's face. FRANK Someone die or something? He suddenly notices Roxanne - both feet are placed firmly in his mouth. FRANK (cursing himself) Oh, Jesus. ROXANNE It's okay. Frank quickly walks up to Roxanne and takes her gently by the arm. FRANK Come on into my office, sweetie. INT. CHANNEL 7 NEWS BUILDING - FRANK'S OFFICE - CONTINUOUS He sits her down on his leather couch, then quickly turns toward his door. FRANK Can we get this woman some water for God's sake? (to Rebecca) I gave you two months off. What're you doing back? People are gonna think I'm a slave driver. 18. ROXANNE Aren't you? FRANK Yeah, but I don't want people to think it. ROXANNE Frank, listen. I want to go back to work. I NEED to go back to work. FRANK ...You're hysterical, aren't you? Frank sits down on the couch and blankets Roxanne with A WARM EMBRACE. ROXANNE What're you doing? FRANK Keeping you warm before you go into shock. (toward the open door) DO I HAVE SLICE OPEN A CAMEL HUMP TO GET A GLASS OF WATER AROUND HERE? A SECRETARY quickly enters with a bottled water. She sets it on the table in front of them and leaves. Roxanne pulls herself out of Frank's grasp and stands up to face him. ROXANNE It was a traumatic experience. Yes, everyone knows Uberman and me were...close. But what I really need - what would really make me better is getting back to work. There's a sudden awkward silence from Frank. FRANK Well, that's going to be... ROXANNE I thought you'd be happy to have me back. 19. FRANK Oh, we are. Honey, nothing makes us happier than to have our girl back, but... ROXANNE Yes? FRANK Things have sorta...changed. ROXANNE In three weeks? FRANK Listen, I'm not one who likes to open up wounds - especially ones that are just starting to scab, but you were sorta our go to girl for the exclusive on Uberman. And now that he's gone...I moved Brad into your anchor spot. ROXANNE (disgusted) Brad? Brad Helms? The man is an idiot. FRANK It's the suits. They think it's time to switch things up. ROXANNE Oh, because they can't use me to get the big story. FRANK C'mon, Roxie. Using is in the nature of what we do. They used you, you used Uberman. Everybody's happy. ROXANNE (defensive) I didn't use him. FRANK Oh, I didn't mean that. I know you two were in love or something. My bad. ROXANNE We were. 20. FRANK And that's great. ROXANNE Very in love. There's a hind of self-doubt in Roxanne's expression, as if she's failed to convince even herself of this. ROXANNE Okay. So, where are they going to move me if Brad has my spot? FRANK ...Human interest. ROXANNE Bake sales and pet stories. FRANK I told them I wouldn't be surprised if you just upped and quit. You busted your ass for that desk. Roxanne can hardly get it out - she's busy swallowing her pride ROXANNE I'll take it. Frank looks up at her, not believing what he's hearing. FRANK What? EXT. ABANDONED METRO CITY LIBRARY - NIGHT Amongst the jungle of high rises, one small building stands out from the rest - A tiny, forgotten piece of 19th century Gothic architecture. LIGHTENING FLASHES, revealing TWO CONCRETE GARGOYLES holding a cracked plaque, reading: METRO CITY LIBRARY. INT. ABANDONED METRO CITY LIBRARY - NIGHT A mixture of old and new. Dusty Victorian furniture and dilapidated bookshelves sit side by side with pristinely futuristic machinery. The building has been converted into Master Mind's new SECRET LAIR. 21. In the center of the main room is a three storey tall GLOWING BLUE ORB. At the base of it is a sign that reads "Reactor - Don't Touch." We PAN OVER to the READING ROOM where Master Mind is sitting on a couch watching TELEVISION. REPORTER ON TELEVISION (O.S.) It's been nearly six weeks, and still no word on the whereabouts of billionaire playboy, and philanthropist, Wayne Scott. Tune in at 11:00 as we look into what has become Metro City's biggest mystery. TELEVISION NARRATOR (O.S.) We now return to "The Hero of our Hearts: The Uberman story." Einstein and Plato come into the room holding a BAG OF LOOT. EINSTEIN Just robbed the diamond exchange. MASTER MIND (feigning pleasure) Great, great. Put it on the pile. Einstein tosses it on a LARGE PILE of purloined valuables in the corner of the room. EINSTEIN Anything else today? MASTER MIND No. Master Mind turns his attention back to the screen. Plato sees that Master Mind is in a funk and tries to snap him out of it. PLATO (cheerfully) Sir, the new reactor is installed. Plato nods to the giant orb. PLATO Do you want to throw the switch? I know how you love to start reactors. 22. MASTER MIND Maybe later. Einstein gives Master Mind a funny look then exchanges glances with Plato before leaving the two of them alone. Without turning away from the TV, Master Mind addresses Plato. MASTER MIND (CONT'D) What is it, Plato? PLATO (nervously) Sir, I can't help but notice that you've been...a little down lately. MASTER MIND When I want your opinion I'll beat it out of you. PLATO Yes, sir, I know, but please forgive my impertinence. It's just that you seem to have lost your lust for our profession. You've stopped going on jobs and spend most of your time watching Uberman specials. Master Mind relaxes slightly and turns to face the window in a classically contemplative pose. After an overdramatic beat... MASTER MIND I have defeated my greatest enemy. I have free reign over Metro City. I have more wealth than a thousand Sultans. I've achieved all I have worked for...so why am I so unhappy? He walks over to a PAINTED PORTRAIT that looks almost exactly like him, except slightly older, maybe meaner - MASTER MIND'S FATHER. MASTER MIND I mean, my father, god rest his evil and tormented soul, raised me straight from the test tube to be a symbol of evil. (MORE) 23. MASTER MIND(cont'd) And, I have accomplished something he had only dreamed about - the destruction of Metro City's champion. I tell you, I've always lived with this unquenchable thirst. I thought it was to make him proud or to get absolute power. But now that I've pretty much accomplished both, I am at a loss. PLATO ...I sort of have a theory about all that. MASTER MIND (snippy) Oh, really? PLATO Well, for one thing, maybe Uberman was more important to you than you thought. MASTER MIND He was a worthy rival. Sometimes I wonder, did he consider me his evil equal or was I just an annoying, little gnat to him? ...What's the second part? PLATO I think you sort of have a thing for Roxanne Ritchi. Master Mind quickly takes his lackey by the throat. MASTER MIND YOU WORM! HOW DARE YOU! WHERE WOULD YOU GET SUCH A NOTION? PLATO Sir, your plans always involve Ms. Ritchi either being kidnapped or placed in danger. If that's not love, I don't know what is. It's the grown up equivalent of dipping her pigtails in the ink well. Don't you see? She's the one treasure that's always escaped you. From Master Mind's expression, we see Plato's words beginning to ring true. 24. INT. RESTURAUNT - DAY Roxanne is having lunch with several girlfriends sitting around her, gabbing. FRIEND #1 I can't believe you came back so soon. FRIEND #2 Are you sure it's not TOO SOON, honey? ROXANNE I just wanted to get back to work. FRIEND #3 What we need to do is get you back on the saddle...the love saddle. Friend 1 and 2 give 3 disapproving looks. FRIEND #3 It's been three weeks. FRIEND #2 She just lost the love of her life, Grace. A WAITER comes by with a tray of CAESAR SALADS and begins setting them out for the ladies. ROXANNE I keep trying to tell people it wasn't really like that. Uberman and I - We were kinda having problems. We broke up. The waiter ALMOST DROPS HIS TRAY AT THIS. The women are too shocked by Roxanne's revelation to notice. FRIEND #1 You broke up with Uberman! FRIEND #3 You must have REALLY, REALLY high standards. I mean, you were dating a god. I mean, what's it take? ROXANNE Maybe someone who's a little more aware of his faults. Someone a little more sensitive. 25. FRIEND #3 Right. Someone who listens, sexy but attainable with cute little cheeks like a hamster and heartbreak in his eyes. She turns to Friend one and two to explain. FRIEND #3 She wants John Cusack. FRIEND #2 The actor? FRIEND #3 No, the famous pediatrist - Yes, the actor. Ever since we were teenagers, Roxanne's totally had the hots for him. ROXANNE Well, until he miraculously comes walking into my life, I'm just going to take a little reflection time for myself. The waiter gets a confused look on his face then slips away as Roxanne and her friends continue to chat away. EXT. RESTURAUNT - DAY The waiter tosses his apron in a trash can, then rolls up his sleeve and presses A STRANGE LOOKING DEVICE STRAPPED TO HIS WRIST. His image gets staticy, like a TV station going out, then disappears - revealing the man's true form underneath: MASTER MIND! MASTER MIND Who the hell is John Cusack? EXT. CITY STREET - DAY A YOUNG MOTHER pushes her baby stroller past a building construction site. ACROSS THE STREET A local POLITICIAN addresses a group of REPORTERS on the sidewalk, including Roxanne. 26. POLITICIAN The Fifth Avenue Renovation Project, which I championed, will breath new life into the downtown area. New life means new jobs and new revenue. ROXANNE Councilman, is it true that your brother-in-law's construction company won the contract for this project? POLITICIAN Well...er...yes, but...look I'm not here to answer a lot of crazy questions... YOUNG MOTHER The young mother stops halfway down the block, reaches into the stroller and tries to comfort her now crying baby. Above her, a CRANE is maneuvering a pile of STEEL GIRDERS to an upper floor. Hal comes around the corner and heads in her direction. CRANE The crane GRINDS TO A HALT. The OPERATOR has a confused look on his face as he moves levers back and forth in an effort to fix the problem. Hal stops a few feet from the woman and stoops down to tie his shoe. CRANE The operator's hand slips off the lever, hitting a RED BUTTON. To his horror the crane DROPS ITS LOAD OF STEEL. HAL AND THE WOMAN The woman looks up to see the girders seconds from crushing her and her baby. She screams. Hal looks up and sees it as well. He starts to run out of the way and crashes into the woman and stroller. ACROSS THE STREET 27. The reporters turns their cameras just in time to catch on film what appears to be Hal pushing the woman to safety just as the GIRDERS CRASH TO THE GROUND. HAL AND MOTHER Tears of joy in her eyes, the woman picks up her baby and kisses it. Hal struggles to catch his breath as the mother turns to him. YOUNG MOTHER Thank you! Thank you for saving me and my baby! She hugs him with her free arm, weeping with joy. HAL (not knowing what she's talking about) Huh? He's a little uncomfortable with the woman's public display of affection and the small child in-between their embrace. HAL (CONT'D) There, there. Hal slowly eases out of the woman's grip. HAL (CONT'D) Okay, we better...well, I hear these little guys smother easy. The reporters rush over and surround Hal and the mother. ROXANNE What's it feel like to be a hero? Hal looks up at Roxanne. Instantly, he's captivated by her beauty. HAL Well...I'm just a man doing what men do. You're Roxanne Ritchi, aren't you? They're suddenly interrupted when another reporter pushes his way in between them. REPORTER Were you scared? 28. HAL Scared? Who had time? The reporters eat this up. INT. ABANDONED METRO CITY LIBRARY - NIGHT TELEVISION John Cusack stands in the rain looking up at a window of a two story house. He holds up a BOOMBOX and "In Your Eyes" by Peter Gabriel begins to play. From the couch, Master Mind and his minions watch. MASTER MIND John Cusack, huh? So all I have to do is have a cute puppy dog stare, be willing to make a fool of myself and - Oh, REMOVE BOTH MY BALLS. He turns to see Da Vinci watching the movie and wiping a tear from his cheek. MASTER MIND Please, get a hold of yourself. INT. BOOKSTORE - NIGHT Roxanne is carrying a large paper coffee cup in her hands as she peruses the isles. She sets it down on a shelf to pull a book out and ends up KNOCKING THE DRINK OVER. ROXANNE Shit. She goes to pick it up when someone bends down and picks it up for her. Looking up to thank him, Roxanne is suddenly stunned speechless - It's popular and critically acclaimed actor JOHN CUSACK, or rather Master Mind disguised as him. "JOHN CUSACK" Oh the humanity - it was a Venti. ROXANNE (stunned) You're...you're. "JOHN CUSACK" Yes, it's me. John Cusack...the actor. 29. He notices the book she's reading. "JOHN CUSACK" Hey, is that Shelly? Wait, I think remember something from that one - Let's see: "My head is screaming `I want you and need you' - my heart it keeps reaching to see you and feel you - yet in the end, I'm alone once again." Wow, I scare even myself. I'm sorry. I'm just really into poetry. Probably because I'm so sensitive and always going to great lengths to express myself. But enough about me. Can I fill you up? ROXANNE (captivated) ...Yes. (catching herself) I mean, excuse me? "JOHN CUSACK" Can I fill you up? Your coffee. ROXANNE Right. INT. BOOKSTORE CAFE' - LATER Roxanne talks as John Cusack listens to her every word intently. ROXANNE I did have a boyfriend - until fairly recently. She suddenly begins to feel the stares around her as passers- by being to notice who she's with. ROXANNE I'm sorry - this is so surreal! "JOHN CUSACK" Yeah, they charge way too much at these places - Now back to your boyfriend. I'm interested and compassionate. I want to know about you. 30. ROXANNE Things were complicated. He was a man married to his work. There was...there was a lot of competition in his line of business. I'm sure you know what that's like. "JOHN CUSACK" Sure. In my business, one thing I have is RIVALS. For example, mine is...uh...Lou Ferr...igno. ROXANNE ...The body-builder who used to play The Hulk on TV? "JOHN CUSACK" Did he? Well, we're always up for the same roles. Did your boyfriend have someone like that? A particular rival that was always getting his goat - so to speak? ROXANNE Well...one rival in particular seemed to get more of his attention than I ever did. But enough about my problems. "JOHN CUSACK" NO, TELL ME MORE!!! Suddenly realizing his outburst, he begins COUGHING to mask it. "JOHN CUSACK" (CONT'D) I'm sorry. I got a whooping cough. Had it ever since Serendipity. I WONDER WHERE OUR REFILLS ARE!!! (fakes cough) See, there it goes again. Please, go on. ROXANNE Right, well, he seemed to need him more than he needed me. "JOHN CUSACK" How do you mean? 31. ROXANNE It was conflict he thrived on. He always said he wouldn't know what to do with himself if Master - I mean, this guy were gone. It was like he needed it, like oxygen. The answer to his mental funk hits him like a bolt of lightening. He turns away from her as if for private time. "JOHN CUSACK" (almost to himself) I think I finally understand...The only logical answer is to recreate that rivalry - or if that's impossible, create one of equal structure. That's it! ROXANNE What? John Cusack snaps out of his dream-like haze realizing she's heard every word. "JOHN CUSACK" Oh, sorry, sorry. Just rehearsing for a part...where I play a man who talks to himself at inappropriate times. In a sudden rush, he rises out of his chair. "JOHN CUSACK" I have to go right now, but I'd really like to see you again - if that's alright. Roxanne looks up at him - She can't help but laugh at the craziness of the situation. ROXANNE I'd love that. INT. ABANDONED METRO CITY LIBRARY - DAY Master storms in the office to find Plato and Einstein playing darts with the original Mona Lisa. EINSTEIN Got her nose! MASTER MIND I've got it! 32. Everyone stops what they're doing upon seeing that their master has returned. MASTER MIND I've got it! MASTER MIND It's plain and simple. Extraordinary minds need extraordinary stimulation. Without that stimulus they wither and die. Therefore, there is only one logical conclusion: I must create a new superhero. EINSTEIN Yeah, maybe that's not such hot idea... MASTER MIND (ignoring him) Prepare for Operation Superhero Genesis! INT. ABANDONED METRO CITY LIBRARY - LABORATORY - DAY The lab is slick, white and ultra modern. Dressed in a lab coat, Master Mind enters through a SLIDING GLASS DOOR rubbing his hands excitedly. MASTER MIND Prepare the subject. He glances down into a large HOLE in the floor to see a naked thirty year old man, SEVERS, shivering. Above the hole, a huge vat dangles precariously. Master Mind steps behind a glass partition next to Plato and Einstein. MASTER MIND (CONT'D) Plato, pour the toxic waste. Plato throws a switch causing the vat to tip hundreds of gallons of green and brown goo into the hole. MASTER MIND (CONT'D) Drainage. The slime is sucked out through the floor, leaving a goo- soaked Severs. 33. Master Mind looks into the pit. MASTER MIND (CONT'D) Well, Severs? SEVERS I feel fine. Just a little sticky, but aside from that everything's completely - BOOM - Severs explodes. A hail of blood and tissue covers Master Mind and his men. For a good ten seconds nobody moves an inch. Finally... MASTER MIND Okay then. INT. ABANDONED METRO CITY LIBRARY - LABORATORY - DAY Through a glass WATER TANK we see a man breathing normally. MASTER MIND And this one? PLATO We attached gills to him. He can breath under water. MASTER MIND Ah. Does he have extraordinary strength? PLATO Well...no. MASTER MIND Can he fly? PLATO No. MASTER MIND Resilient to weapons fire? PLATO No. MASTER MIND He just breathes under water, then. PLATO Ah...yeah. 34. Master Mind rolls his eyes and walks away. INT. ABANDONED METRO CITY LIBRARY - LABORATORY - DAY The next guinea-pig, STENWICK, is standing in a sealed glass tube not much wider than himself. MASTER MIND Plato, the radioactive spider, please. Plato throws the switch DROPPING A SINGLE SPIDER onto Stenwick's arm. Stenwick looks and winces as it bites him. STENWICK Ow! He brushes the spider off. MASTER MIND Anything, Stenwick? STENWICK (shaken) No. Ah...sir, I didn't know this was about spiders. I have a pretty severe case of arachnophobia. Master Mind thinks for a moment, then turns to Plato. MASTER MIND We're gonna need more venom. Plato throws another switch, this time DUMPING THOUSANDS OF SPIDERS on poor Stenwick. His SCREAMS begin to fade as he's engulfed with swarms of crawling arachnids. MASTER MIND (CONT'D) How `bout now, Stenwick? ....Stenwick? INT. ABANDONED METRO CITY LIBRARY - OFFICE - DAY Master Mind is pacing back and forth. The muted TV plays in the background. MASTER MIND This has proven to be a challenge. I just don't know what I want. What do I want? 35. He stares at Einstein, Da Vinci and Plato, but they offer no advice. MASTER MIND (CONT'D) I want a man of moral fiber with a strong sense of right and wrong. Someone who doesn't seek power - instead, they must have it thrust upon them and find, within themselves, the courage to rise to the occasion. Einstein lets out a short laugh, getting everyone's attention. EINSTEIN Yeah, well, it sounds like what you want is Uberman. Master Mind snaps the fingers of his non-metal hand. MASTER MIND That's it! Why make a copy when the real thing will do? The lackeys look at each other, they can't believe what they're hearing. EINSTEIN I was just kidding, sir. In case you forgot, you actually burned Uberman alive. MASTER MIND Then we'll make a new one. Plato, bring me the box! MINUTES LATER Master Mind and the lackeys stand in a circle around a small table. Plato places a STAINLESS STEEL CHEST in the tables center. As Master Mind opens it, he's immediately doused in WHITE GLOW emanating from inside. MASTER MIND Behold - Uberessence. The very thing that gave Uberman his superhuman powers. 36. EINSTEIN Where the hell did you get that? MASTER MIND Oh, I shot him with a power sucking gun and had this idea to use this to clone a whole army of evil Ubermen. I'm not sure why I never got around to following up with that. PLATO I believe he defeated you before you could, master. MASTER MIND ...Right. Man, he was good! DA VINCI You want another volunteer, sir? MASTER MIND Not another volunteer driven by the need for personal gain. Somebody else, somebody pure. Master Mind turns to see an INTERVIEW WITH HAL playing on the muted television. Underneath his face is a blue caption with white lettering that reads: "Hal Stewart - Metro City's Newest Hero?" NEWS REPORTER ...who risked his own life to save that of a young mother and her child. HAL Please, please, you're embarrassing me. I saw someone in need and I helped them. What more can we ask of ourselves. I ask you, what more? A smile creeps across the evil one's face. MASTER MIND (CONT'D) Somebody like him! EXT. CITY STREET - DAY Plato is sitting in the van, staring into a pair of binoculars as he speaks on a cellphone. 37. PLATO Yeah, sir. This guy is a real piece of work. He used to teach bowling at Kingpin's. INT. MASTER MIND'S HIDEOUT - DAY Master Mind is sitting with his feet up on a computer console as he speaks to Plato. MASTER MIND (into phone) A modest profession to brilliantly hide his true heroic nature. I love it. EXT. CITY STREET - DAY PLATO Then you are absolutely going to love this - We follow Plato's line of sight across the street where we see HAL PLAYING WITH A LARGE GROUP OF BLIND CHILDREN. PLATO - He volunteers at a school for the blind. INT. MASTER MIND'S HIDEOUT - DAY Intrigued, he suddenly sits up in his chair. MASTER MIND He volunteers. He doesn't ask for any reward for his deeds. The fates are shining down on me. This Mr. Stewart is truly an unselfish soul. EXT. BLIND SCHOOL - DAY From a distance, Hal seems to be consoling an upset child who's sitting on a rock. But up close... HAL You greedy little bastard. I already gave you a twenty. BLIND KID Hey, you want me to play along? Then pay up, bitch! 38. HAL Fine, but you better be convincing. He gives the kid a bill out of his wallet and looks over his shoulder to see a HOT TEACHER walking toward them. HAL Here she comes, go to work. Like a miniature Brando, the blind kid buries his face in his hands and begins to cry. BLIND KID (weeping) Why can't I see! Why God? Hal puts a warm consoling hand on the weeping boy's shoulder. HAL Hey, Peter. C'mon champ, let me look at you. The Hot Teacher stops and curiously watches from a distance. The boy looks up at Hal, tears running down his dark sunglasses - he should get an Oscar. HAL You know, in life we're all given no more than we can bear. This happened to you maybe because you were meant to rise above it - Maybe to be an inspiration to the other little Peteys out there. BLIND KID You really think so, Hal? HAL Hey, does it LOOK like I'm lying? Now c'mon, go feel your way to class before you get your little butt suspended. The boy stands up and is about to take off. HAL Petey, wait a minute. Hal uses his shirt sleeve to wipe the tears away from the boy's face before sending him on his way. 39. The Hot Teacher grabs her chest. Her heart is about to absolutely melt. HAL Don't run into anything! EXT. STREET - CONTINUOUS Plato lowers his binoculars. From his perspective, Hal should be next in line for popehood. PLATO I think I've seen enough, sir. This is your guy. MASTER MIND (O.S.) (over radio) Then return to base. We have much work to do. Plato starts up the van and pulls away. INT. BAR - DAY It's a busy night. A couple of trucker types are shooting pool as the bartender slings drinks. Hal is nursing a beer at the bar when he suddenly notices a very ATTRACTIVE WOMAN sitting next to him. As he goes to straighten his stool-posture, Hal suddenly catches himself on the bar's TELEVISION - it's a story about how he saved the woman and her baby at the construction site. He turns back to the Attractive Woman next to him, then back to the TV. A plan of attack is forming. HAL (obviously playing it up for the woman's benefit) Oh, there it is again. This is really getting embarrassing now. The woman looks up at the screen and gives Hal a double-take. ATTRACTIVE WOMAN Oh my God! It's you! You're the man who saved that woman and her baby the other day! It is you, isn't it? TRUCKER #1, getting a drink at the bar next to them, OVERHEARS. 40. Hal rolls his eyes and puts his hands up in the air. HAL (to Attractive Woman) Oh, crap. You got me. TRUCKER#1 taps Hal on the shoulder. TRUCKER#1 Let me tell you something. That was just about the bravest damn thing I've ever witnessed. (he turns to the rest of the bar) Hey, everybody! This guy's the hero from TV! The bar ERUPTS IN CHEERS. MOMENTS LATER Hal is riding on the shoulders of TRUCKER#2 and TRUCKER#3 as `I'm Holding Out For A Hero' plays on the jukebox. TRUCKER#1 suddenly puts his hands in the air. The room quickly goes silent. TRUCKER#1 I want to give you something. He reaches into his pocket and takes out a medal. He holds it up in the air for everyone to see. TRUCKER#1 (CONT'D) Lost my whole platoon. They were a lot a good boys, a lot of good boys. That was just the way things were in "The Grenada." I'd rather a real hero have this. Trucker#1 gives the medal to a speechless Hal. ATTRACTIVE WOMAN Hey, you're on TV again. The crowd looks up at the Television. TELEVISION - CONTINUOUS The anchor man, BRAD HELMS (early 40's, amazing mustache), suddenly has a memo passed to him. 41. BRAD HELMS This just in. Upon a second look at that tape from this morning, which we'll now replay for you, it appears it was not the heroic act it first seemed to be. The tape shows Hal running in slow motion. BRAD HELMS (O.S.) (CONT'D) With the tape slowed down you can actually see the man push the woman and her child out of the way in an effort to save his own life. The tape shows Hal, in a clear act of self-preservation, pushing the woman and child out of the way. CUT BACK TO: INT. BAR - CONTINUOUS In unison, everyone turns their heads back to Hal. HAL I guess that looks kinda bad. Trucker#1 snatches his medal back. EXT. NEARBY ROOF - NIGHT Master Mind, Da Vinci and Plato look down, spotting Hal cutting through a dark alley. DA VINCI There he is, boss. Da Vinci hands Master Mind a fantastic looking silver rifle. MASTER MIND Now, we're sure this won't kill him? PLATO Yes, sir. He'll just feel a slight electrical shock. MASTER MIND Good. Master Mind raises the rifle and aims it at Hal. 42. EXT. ALLEY - NIGHT Hal wipes the blood from his nose with his shirtsleeve. A LIGHTENING BOLT suddenly zaps Hal in the back. His teeth spark and arc electrons as his entire body shakes and shudders violently. He finally collapses, knocking over a row of garbage cans. EXT. NEARBY ROOF - NIGHT An angry Master Mind slaps Plato. MASTER MIND Slight electrical shock? EXT. ALLEY - NIGHT Hal lies flat on his back, his jacket smoldering. Dazed, he slowly rises to his feet and looks up at the sky. HAL God, I hate the weather in this city. Hal walks off into the night as he attempts to slap the emitting smoke from his jacket. EXT. NEARBY ROOF - NIGHT Master Mind turns to Da Vinci. MASTER MIND Follow him. INT. HAL'S APARTMENT - NIGHT It's a dirty, small studio. Laundry lies everywhere, dishes are piled in the sink and the litter box looks like a minefield. Hal comes staggering in. Through his POV we see the lights wobble and streak like a hallucination. He shakes his head trying to clear thing up, but it looks worse. Hal makes his way to the kitchen table and plops down on a chair. The room begins to swim. His CAT jumps on the table and sits down in front of him. 43. From Hal's POV the cat's face looks like we're seeing it through a kaleidoscope. Hal seems fascinated by it. CAT You don't look so good, man. HAL I don't feel good. I was struck by freaking lightening. Suddenly Hal realizes his cat's talking to him. HAL (CONT'D) AAAAAAHHHHH! You can talk? CAT No, you're just hallucinating. By the way, we're out of orange juice. HAL AAAAAAHHHHH! Hal jumps up, trips over a cardboard box and knocks himself out on the coffee table. INT. HAL'S APARTMENT - MORNING Hal lies in the same position we left him last night. He sits up and grabs his head. He looks like he has the worst hangover in the world. Finally, he remembers last night. He looks around, but not really sure what he's looking for. HAL Man... Shaking his head, he walks to the kitchen and opens the refrigerator. He pulls out an orange juice container and puts it to his mouth. It's empty. As if suddenly remembering something he looks from the carton to the cat, who is busy cleaning himself. He shakes the thought from his mind. BATHROOM Hal lifts the seat and unbuckles his pants. 44. HAL'S FACE He stares at the ceiling with half closed eyes. The inevitable sound of urine hitting water starts. A content look washes over his face. There is a distinct sound of porcelain CRACKING and SPLINTERING. The sound intensifies. Hal looks down to see his URINE STREAM SMASHING THE TOILET. HAL (CONT'D) Oh, God! He whips his stream away only to cut a LONG RIP IN THE WALL. HAL (CONT'D) Oh, God! He freaks out and begins to lose control of his flow as it destroys everything he accidently aims at; the bathroom mirror, a bottle of cheap cologne, the bathroom window. HAL (CONT'D) Oh, God! He aims back for the toilet, which is pretty much rubble now, to see the floor give way. Finally, the pee stops and he glances down the hole. He sees his downstairs NEIGHBOR sitting at his breakfast table. He has a fork halfway to his mouth as he stares at the smashed toilet on his pancakes. EXT. STREET - DAY Hal turns the corner to see his bus pulling away from the stop. HAL Wait! He starts running after it. ZOOM - HE TAKES OFF LIKE LIGHTENING. HAL (CONT'D) Whoa, whoa, whoa! Unable to stop, he SLAMS INTO THE BACK OF THE BUS and falls back to the ground. 45. As the bus continues on he sees an INDENTATION of his torso right below the rear window. Stunned, to say the least, he rises to his feet. HAL (CONT'D) Something's not right here. He slaps himself in the face as hard as he can. HAL (CONT'D) Wake up! Wake up, Hal! HONK! Hal spins around to see a car barreling toward him. He goes to jump out of the way - ZOOM - he FLIES TWO STORIES UP, nails a building and comes crashing back down to the sidewalk. Hal sits up, disheveled and scared. HAL (CONT'D) Okay, okay. Let's get it together, man. He closes his eyes in an attempt to will back his sanity. HAL (CONT'D) This is just some sort of...episode. It will pass, it will pass. He opens his eyes and looks down the street. A BEAUTIFUL NAKED WOMAN is coming toward him. HAL (CONT'D) Well, not too fast I hope. As she passes him and turns the corner out of his view he catches ANOTHER NAKED WOMAN - an old disgusting one. HAL (CONT'D) Yes, fast, fast! He turns away from her in horror only to see AN ENTIRE BLOCK OF NAKED PEOPLE going about their business. He rubs his eyes and looks down the street again. Everyone has returned to a clothed state. 46. He relaxes a little until he looks down and notices that he's floating a foot off the ground. HAL (CONT'D) I think I need to go home. INT. HAL'S APARTMENT - DAY Hal's front door CREAKS as it slowly opens, revealing Master Mind. He walks over to the bathroom and smiles to himself as he notices the giant hole in the floor. MASTER MIND Welcome to your second birth, Hal Stewart. Master Mind continues to survey the room. He stops to look over a "KARATE KID" POSTER on Hal's living room wall. He focuses on the majestic image of Pat Morita teaching a young Ralph Macchio to kick. MASTER MIND (CONT'D) Instruction is very important in the formative years. Every hero needs a mentor, a father figure to look up to. He presses his special watch, causing his body to MORPH INTO THE SPITTING-IMAGE OF PAT MORITA. "PAT MORITA" Perfect. INT. HAL'S APARTMENT - DAY Hal enters, grabs a bottle of vodka from atop of the fridge and takes a long pull from it. VOICE (O.S.) A man will usually find that if he drinks from a bottle, eventually, the bottle drinks from him. Hal does a SPIT TAKE. In the corner a darkened figure stands. HAL Who are you!? 47. VOICE I am the guide on your journey. Fate has chosen you to be it's champion. Pat Morita steps out from the shadows. Hal passes out again. LATER We are close on Hal's face as his eyes flutter open. He appears to be lying on the couch. He hunches up on his elbows, looks around, but everything is as it seems. He lays his head back down. HAL Thank God. It was a dream. Man, I must be losing it. A voice sounds right next to his ear. "PAT MORITA" (O.S.) You know you're out of orange juice? Hal leaps up to find he's been resting his head on Pat's lap. HAL Jesus! This isn't happening, this isn't happening. Hal backs away and trips over a box. "PAT MORITA" Calm. All things must be filtered through calmness. HAL Bullshit! Sometimes it's best to freak out. "PAT MORITA" I think we must work on your attitude first. HAL Look I'm gonna call the cops in about two seconds if you don't get out of here. 48. Pat rises and walks to Hal. He's so calm it makes Hal calm. "PAT MORITA" Are you calm now? HAL Yeah, I'm okay. Pat slaps him across the face hard. "PAT MORITA" Good, because we've got a lot of work to do. Hal grabs his jaw. HAL What the hell was that for? "PAT MORITA" Rule number one: expect the unexpected. HAL Can you just tell me what this is all about? "PAT MORITA" The heavens are not in the habit of bestowing a gift such as this to just anyone. You are being rewarded for being a man of great moral fortitude with an unwavering belief in humanity. HAL That's me alright. "PAT MORITA" I am to train you so you may fulfill your destiny to defeat the great menace to Metro City: Master Mind. Pat gets up and walks toward the door. "PAT MORITA" (CONT'D) Come. HAL We're are we going? 49. "PAT MORITA" To train. EXT. PAT'S CAR - DAY Pat is sitting in the driver's seat. The car is bumping up and down. "PAT MORITA" Strength is just as much in the mind as it is the muscle. Remember, both need to be exercised. We PULL BACK to see Hal lifting the car up over his head. He's hardly straining. HAL I'M LIFTING A FREAKING CAR!!! Pat leans on the HORN. "PAT MORITA" Hey, Corky? You listening? Two highly attractive female joggers run by. They're clearly impressed with Hal's show of strength. He smiles and mouths a "hello." HAL Yeah, work both muscles. EXT. DESERT - DAY Pat cocks back the chamber of a .357 MAGNUM. He holds it up and carefully takes aim...at Hal's chest. "PAT MORITA" Trust me. HAL What are you doing!? "PAT MORITA" An invulnerability test. Something wrong? HAL Uh...yeah. I would prefer not to get shot. Do not fire that thing! Frustrated, Pat lowers the gun. 50. "PAT MORITA" You're bulletproof. HAL Okay, do you know that for sure? Pat quickly aims and fires. Hal lets out a high pitched scream as the bullet ricochets off his chest. "PAT MORITA" I do now. Hal looks down at his chest, not so much as a scratch. HAL You suck. EXT. SKY - DAY Hal is in the air flying in a sitting position. He's weaving back and forth. HAL Ice Man, I got a bogie on my tail. Two Russian Migs coming in hard and fast. "PAT MORITA" Hey! HAL What? Hal looks down to see Pat Morita yelling at him from the roof of a building down below. "PAT MORITA" What did I tell you? Stomach down, hands up. Hal sighs and assumes the proper superhero in-flight position. HAL God, I feel so gay. Pat's CELL PHONE begins to RING. He answers it. "PAT MORITA" (in Master Mind voice) What is it? 51. ROXANNE (V.O.) John? Pat panics. He looks up to make sure no one is in earshot. He sees Hal now doing somersaults in the air. HAL YEEEE HAWWWW! Pat turns his attention back to the phone, talking in his John Cusack voice. "PAT MORITA" (in Cusack voice) Yes, it's John Cusack. ROXANNE (V.O.) Hi, it's Roxanne. Listen, I...I really enjoyed talking with you the other day. "PAT MORITA" ...As did I. ROXANNE (V.O.) Great. God, I feel really silly, and if you have a lot going on I totally understand. But, I was wondering if you maybe wanted to have lunch. He can't believe what he's hearing. "PAT MORITA" (excited) I'd love to! He quickly recovers his composure. "PAT MORITA" (CONT'D) I mean, I AM a little hungry. ROXANNE (V.O.) Great. How does the park sound, around noon-ish? "PAT MORITA" Sure! ROXANNE (V.O.) Great, see you then. 52. Pat hangs up the phone and returns it to his pocket as Hal lands behind him. HAL WHOOOOA! Man, that is so cool. It's like fly - Oh my God, I almost said it was like flying. "PAT MORITA" For the rest of the day I want you to continue to practice your flying posture. HAL Why, where're ya going? "PAT MORITA" ...To do something...mysterious ...and Asian. HAL Say no more, bro. I'll just keep at it, then. EXT. PARK - DAY John Cusack and Roxanne eat WRAPPED SANDWICHES while walking through Metro City Park. ROXANNE How's your sandwich? "JOHN CUSACK" It's quite delicious. ROXANNE Hope you don't think I'm too forward. Some men are intimidated when a woman asks them out. I just find you really easy to talk to. "JOHN CUSACK" And I you. ROXANNE You know, you're not at all like you are in the movies. "JOHN CUSACK" I'm not? 53. ROXANNE Yeah. I don't know - You have this strange, refined way of speaking. "JOHN CUSACK" I do? That is most interesting. ROXANNE Anyway, when we were talking the other day I just felt, even though we only talked for a couple of hours, that we've known each other for years. "JOHN CUSACK" I know just what you mean. Roxanne bites into her sandwich. ROXANNE You know what? This sandwich is disgusting. She tosses it in a nearby garbage can. ROXANNE (CONT'D) Of course I already ate half of it. I wonder what that says about my character? "JOHN CUSACK" It means you don't give up on a sandwich. You see that it has potential, and you give it every chance to be all it can be. Roxanne smiles at his analogy. ROXANNE Thanks, but knowing me, I was probably projecting my expectations of what a lunch should be on the sandwich. It might have been okay at first, but I just made it bitter. John Cusack notices Roxanne's smile starting to fade. "JOHN CUSACK" Is that what happened with your last sandwich - I mean, boyfriend? 54. ROXANNE When I look back, I probably shouldn't of expected so much from him. He was already a giving person. You know, one of those go out and save the world types. "JOHN CUSACK" I've run into a few. ROXANNE I was selfish, I guess. I didn't want to share him with anybody else. "JOHN CUSACK" It sounds like he was a special man. ROXANNE They broke the mold. John Cusack arches his eyebrow in a very familiar manner. "JOHN CUSACK" Perhaps not. INT. ABANDONED WAREHOUSE - DAY Hal walks up to Pat Morita sporting a Lone Ranger-type mask and wearing a purple and red superhero costume. It's not unlike Uberman's except for a giant "T" on his chest. (From here on, Hal is referred to as TITAN) TITAN What's the "T" stand for? "PAT MORITA" Titan. TITAN What's that supposed to mean? "PAT MORITA" It's from Roman mythology. Zeus's father...oh, just go with it. You look perfect. TITAN I don't think this mask is big enough. Are you sure no one is gonna recognize me? 55. "PAT MORITA" It's fine, just don't slouch. It's all in the posture. He grabs Titan's shoulders like a proud papa. "PAT MORITA" (CONT'D) It is time. INT. BANK - DAY There is a long line of people snaked around the velvet ropes. They're all waiting for their chance at the one open teller window. Four men wearing BEATLES MASKS(JOHN,PAUL,GEORGE,AND RINGO)and CARRYING SHOTGUNS enter the bank. John fires a shot in the air, sending everyone into an immediate panic. JOHN Alright folks, this is a robbery. Nobody moves - yadda, yadda, yadda... Ringo jumps over the teller wall and starts stuffing bills into a bag. As John and Paul cover the crowd, George goes to the corner office and puts a gun to the BANK MANAGER'S head. GEORGE The safe. Let's go. BANK MANAGER Okay, just don't hurt anyone. GEORGE Yeah, yeah, yeah. George leads him out by the collar. CRASH - Titan smashes through the window and lands in a bold superhero stance with hands on hips. TITAN Well, boys, there's no need for all this just to get the free toaster. Paul cocks his gun. 56. PAUL What are you suppose to be? We move in for a nice dramatic close up. TITAN Justice. GEORGE Well, justice, suck on this... George, John and Paul open fire on Titan. He just stands there and yawns as the bullets bounce off him. With their guns empty the three just stare at him in amazement. TITAN Now it's my turn. He turns to George. TITAN (CONT'D) Hey, George, here comes the sun. Titan grabs George and throws him into a fluorescent light fixture in the ceiling. Paul tries to run for the door. Titan snatches the collar of his jacket. TITAN (CONT'D) Say, Paul, your mother should know...that you're a scumbag. He tosses Paul out the window and into a parked DELIVERY TRUCK. Titan turns around just as John hits him with the butt of his shotgun. It instantly breaks apart in his hands. Titan lifts him like a rag doll up into the air. TITAN (CONT'D) John, all you need is love... He throws John who lands on top of a cubical wall - GROIN FIRST. TITAN (CONT'D) ...and a good urologist. 57. Titan effortlessly hops over the teller wall to find Ringo cowering on the floor. He grabs him by the shirt and lifts him up. HAL Well, Ringo...um...um...you're under arrest. EXT. BANK - DAY Titan walks out of the bank with Ringo and George under his arm. He's suddenly swarmed by a group of television reporters, including Roxanne. Across the street is Pat Morita. He watches Titan's first news conference with great anxiety. BANK MANAGER (to Hal) On behalf of the First National Bank of Metro City, I'd like to offer you a reward for your act of bravery. He hands Titan a check. TITAN (reading) Ten thousand dollars! Titan looks over to Pat, who violently shakes his head no. TITAN (CONT'D) (unenthusiastically) I...can't except this. Law and order is it's own...um...reward. Pat gives him the thumbs up. Pat turns, suddenly seeing Roxanne with her camera crew. Captivated, his eyes lock on her. Meanwhile, Roxanne and her cameraman, SETH, are maneuvering around the crowd to get closer to Titan. BRAD HELMS (O.S.) Not so fast, Roxanne. They both turn to see Roxanne's reporter rival Brad Helms, Geraldo without the class, and his cameraman, FRANK. BRAD HELMS This story's mine. 58. ROXANNE Listen, Brad. We were just in the area. I was just trying to - BRAD HELMS I've been in this business long enough to know pretty well what you were "just trying to do." Besides, I heard you couldn't take the big game anymore and were put on fluff detail? Dejected, Roxanne turns and motions for Seth to turn the camera off. SETH You're not gonna take that from him, are you? ROXANNE He's right. Old habit, I guess. (to Brad) We'll get out of your way. As they walk off, Brad makes a comment to Frank loud enough for her to hear. BRAD HELMS Besides, I'm sure there's a pancake supper somewhere that needs covering. INT. ABANDONED METRO CITY LIBRARY - OFFICE - DAY ON TELEVISION We see the news conference on the bank's steps. In the corner of the screen is written: "recorded earlier." BRAD HELMS For months now, since the death of Uberman, the citizens of Metro City have been holding out for a hero. Well, it appears they won't have to hold out for much longer as a new costumed crusader has suddenly stormed onto the scene. Today, at the Metro Savings and Trust, a masked mystery man single-handedly defeated "The Fab Four Gang." Just who is this new caped avenger? Brad holds the microphone to Titan's face. 59. BRAD HELMS I'm sure all of our viewers are now wondering, what's the "T" stand for? TITAN It's a message to all the scum out there. Uberman may be gone, but Metro City has a new protector, and his name is "Tighten!" Another reporter leans in. REPORTER How do you spell that? We PULL BACK to see Plato and Da Vinci watching this spectacle. Master Mind is sitting with them, reading a NEWSPAPER. MASTER MIND (reading paper) Oh, for heaven's sake. I can't believe it. He misspelled his name. Master Mind holds up the newspaper. The headline reads "Metro's New Hero: Tighten." MASTER MIND (CONT'D) No matter, I suppose. Master Mind throws the paper on the floor and begins to pace around the room with his arms folded behind his back. MASTER MIND (CONT'D) We've now fully established Titan as Metro City's hero. They will love him just as they loved Uberman. Everything is going according to plan. Einstein leans over and whispers in Plato's ear. EINSTEIN (whispering) Yeah, if the plan is getting us in jail. Master Mind turns around, facing Einstein. He walks over, standing face to face with the rebellious henchmen. 60. MASTER MIND You know, Einstein, maybe I should have called you Socrates. He also didn't know when to keep his thoughts to himself. EINSTEIN I just fail to see the point in all of this. I mean, why are we creating another superhero when it was such a pain in the ass for you to get rid of the other one? I mean, Uberman is destroyed, we should be using this opportunity to...to... MASTER MIND To what? EINSTEIN I don't know. To take over the weather, space, the world - whatever super villains are SUPPOSED to do. MASTER MIND The reason someone like you will always be a minion is because you have no foresight. We take over the earth, like you said. Then what? Women? Cars? Money? Even the grandest treasures will lose their lustre if you don't have someone to hold them over. Einstein throws up his hands. He's had enough. He pulls off his wig and throws it to the floor. EINSTEIN That's it! This balance of the force bullshit is getting way too Oprah for me. I'm blowing. Who's with me? MASTER MIND You dare? EINSTEIN Yeah, I dare. I'm sick of wearing stupid costumes, and I'm sick of working for a super villain who's turning into a softie. 61. Plato and Da Vinci's mouths drop to the floor. They turn to Master Mind for his rebuttal. MASTER MIND What - did - you - call me? EINSTEIN You heard me. You used to be an inhuman monster, now look at you. You're creating super heroes, you don't go with us on robberies anymore, it's been days since you threatened anyone, oh, and not to mention this Roxanne Ritchi thing. MASTER MIND THAT is none of your business, knave! EINSTEIN Hey, you guys haven't sealed the deal yet, have you? MASTER MIND Silence! EINSTEIN (In a woman's voice) Oh, Master, your head is so big. MASTER MIND I'm warning you, Einstein. EINSTEIN (In a woman's voice) Take me! MASTER MIND I said silence! With his metal gauntlet Master Mind grabs Einstein by the throat and lifts him into the air. Einstein looks frightened as he tries to pry himself free of Master Mind's grip. Master Mind's eyes soften as if his heart is suddenly not into what he's about to do. He let's Einstein drop to the floor. MASTER MIND (CONT'D) Get out of my sight. 62. EXT. RESTAURANT - NIGHT Roxanne and John Cusack are eating on the outside patio of a fancy restaurant. ROXANNE Don't get me wrong, I love being a reporter. I don't think I could do anything else. It's the consequences of what we do that I'm having a problem with. He listens intently as he refills her glass with wine. "JOHN CUSACK" That's where journalistic responsibility comes in, no? ROXANNE It's supposed to. "JOHN CUSACK" Sounds to me like you're running from something. ROXANNE I got someone I cared about killed. If it wasn't for me, he wouldn't have been involved. John suddenly gets a disturbed look in his eye, realizing what she's talking about. He reaches across the table and takes her hand. "JOHN CUSACK" You can't blame yourself. My father used to say each of us must answer the great call to truly feel alive. ROXANNE Was he an actor? "JOHN CUSACK" ...No. He was...a landscaper. And a horrible one. I mean he would fail time and time again at his...landscaping. And sometimes he'd get pretty beaten up or thrown in jail - ROXANNE Jail? 63. "JOHN CUSACK" My point is he took the good with the bad. He grew a little each time. Improved, learned. ROXANNE Was he ever successful? "JOHN CUSACK" God, no...but don't let deter you. Roxanne LAUGHS. ROXANNE Thanks for this. You know, this is embarrassing, but it's been a long time since I - It's starting to lightly sprinkle. Roxanne looks up. ROXANNE (CONT'D) I think it's starting to rain. We might want to find a table inside. "JOHN CUSACK" What were you gonna say? ROXANNE Oh, I was gonna say...It's been a long time since...well, I've been with someone I...enjoy being with. John Cusack smiles warmly and raises his glass for a toast. "JOHN CUSACK" To people who enjoy being with each other. They go to clang glasses, when the rain suddenly causes John Cusack's disguise generator to short. His true form of Master Mind is briefly revealed to Roxanne as a BOLT OF ELECTRICITY encircles his body. Roxanne drops her glass and jumps out of her seat. MASTER MIND (CONT'D) Oh, no. Don't look at me. LIKE A BROKEN TV the image keeps switching between MASTER MIND AND JOHN CUSACK. 64. As Master Mind starts to franticly slap at his watch, the Cusack disguise begins to hold steady. He nonchalantly returns to cutting his steak. "JOHN CUSACK" Okay, never mind that. Now, where were we? Roxanne grabs his glass and throws the drink in his face, causing the generator to short out permanently. Master Mind now sits in his true blue form. ROXANNE Oh my God. MASTER MIND You're not gonna get all freaky about this, are you? ROXANNE This...this is too much, even for you. God, I go out with you, tell you my innermost thoughts. MASTER MIND I only did this because I wanted to talk to you on the same level. You know, without all the baggage? ROXANNE Baggage? You burned my boyfriend alive, you sick son-of-a-bitch! MASTER MIND You see, that's exactly what I'm talking about. Roxanne starts to walk away. MASTER MIND (CONT'D) Roxanne! ROXANNE Stay away from me. Master Mind sinks back down to his chair. Despite the now heavy rain bombarding him, he returns to his food. Several resturaunt patron's are looking at him through the window. 65. Our villain turns to them, giving them a villainous glare. MASTER MIND What? INT. MASTER MIND'S BEDROOM - NIGHT Master Mind is lying on his back, wide awake. MASTER MIND (mumbling to himself) Stupid. What was I thinking? Plato, it's his fault. He's the one who sent me on this weak-willed path. I'll filet his scrotum for this. Me, a creature of evil, in love with Roxanne Ritchi. Preposterous. I hardly give such matters thought He rolls onto his side. He yawns and closes his eyes. Suddenly, they shoot back open. CUT TO: EXT. ROXANNE'S APARTMENT - NIGHT Master Mind pulls up in a blue Rolls Royce, across the street from Roxanne's apartment He stares up at the building, hoping to catch a glimpse of her. Finally, she appears, primping her hair in her apartment window's reflection. MASTER MIND I should just go up there and just lay it all out to her. "Roxanne, I like you - I always have. Oh, and I'm sorry I blew up your ex. (realizing the absurdity of his words) Yeah, that would go over like a pants-less clown at a child's birthday party. What the hell am I even doing here? Who cares what she thinks? I'm a supervillain and here I am acting like a love struck schoolboy. Forget this. I control my own destiny! 66. He turns the ignition key - NOTHING HAPPENS. He repeats but gets the same results. MASTER MIND (CONT'D) (disgusted) Perfect. INT. ROXANNE'S APARTMENT - NIGHT She pulls a pack of smokes off her night stand. Empty. ROXANNE Damn. She grabs her long coat and throws it over her robe. EXT. ROXANNE'S APARTMENT BUILDING Roxanne steps outside. ROXANNE Please be open. Across the street is a liquor store. The light is still on. ROXANNE (CONT'D) Thank God. She walks across the street, passing in front of Master Mind's car. Spotting her, he sinks down in his seat. Roxanne walks by, totally unaware of his presence. Relieved, Master Mind sits back up and watches her go into the store. INT. LIQUOR STORE - NIGHT Roxanne walks up to an elderly Korean SHOPKEEPER at the counter. ROXANNE A pack of Lady Strikes, please. EXT. MASTER MIND'S CAR - NIGHT Master Mind is talking on his cell phone. MASTER MIND Hello, Triple A? 67. He suddenly spots something across the street. EXT. LIQUOR STORE - NIGHT A HOODLUM walks up to the entrance of the store and pulls out a gun from under his coat. EXT. MASTER MIND'S CAR - NIGHT Master Mind stares in shock. MASTER MIND I'll call you back. He hangs up the phone and watches the Hoodlum go inside the store. INT. LIQUOR STORE - NIGHT The Hoodlum reaches across the counter and grabs a fist full of cash from the register. SHOPKEEPER Hey! SHOTGUN HOODLUM Shut up, Gramps. He turns to Roxanne, spotting a GOLD NECKLACE around her neck. SHOTGUN HOODLUM (CONT'D) Gimme that necklace! ROXANNE I don't think so. The Hoodlum cocks his shotgun. SHOTGUN HOODLUM I said give it to me! MASTER MIND (O.S.) The lady said no. The hoodlum turns around to see Master Mind in the doorway holding a STRANGE-LOOKING HAND CANNON (GOO GUN) with knobs and blinking lights. The hoodlum starts to laugh. 68. SHOTGUN HOODLUM What the hell's that? A super soaker? MASTER MIND No, it's a goo gun. The hoodlum turns his gun to Master Mind. SHOTGUN HOODLUM Yeah, what's it do? MASTER MIND It goos. Master Mind fires the cannon. It instantly covers the store in a cloud of SMOKE. The smoke clears to reveal the hoodlum STUCK TO THE WALL, covered in a thick, GREEN GUNK. Roxanne stares at him, dumbfounded. MASTER MIND (CONT'D) It's...a prototype. Master Mind starts to walk out when he's suddenly confronted by the shopkeeper. SHOPKEEPER I know you! You Master Brain guy. You a hero. Master Mind points the goo gun at him. MASTER MIND Don't - EVER - say that again. EXT. LIQUOR STORE - NIGHT Master Mind walks out with the cannon resting on his shoulder like he's a short timer in Da Nang. Roxanne follows shortly behind him. ROXANNE Hey! Master Mind turns around. ROXANNE (CONT'D) Are you following me or something? 69. MASTER MIND Don't flatter yourself. He turns away and continues walking. Roxanne runs in front of him blocking his way. ROXANNE Don't walk away from me when I'm talking to you. Finally it occurs to her what's going on. ROXANNE (CONT'D) What a minute...all that stuff you use to say to me when Uberman was alive - about me being the loyal queen by your side as you rule over Metro City. That wasn't just super villain rhetoric, was it? You actually meant it! MASTER MIND My, someone has a rather high opinion of themselves. They stare at each other in silence, their glares locked in conflict. ROXANNE (coldly) Do you really think I would be with someone like you? This stings Master Mind to the bone. And after a brief contemplation, he reaches the only logical, painful conclusion. MASTER MIND No. With that, Master Mind exits into the night, leaving Roxanne with a baffled expression on her face. INT. ABANDONED METRO CITY LIBRARY - NIGHT Master Mind enters in a huff. Da Vinci closes the door behind him as Plato notices his master's agitated state. PLATO Everything alright, sir? Master Mind GRABS PLATO BY THE GROIN with his metal gauntlet causing Plato's eyes to bulge in pain. 70. MASTER MIND (overly calm) Fine, why do you ask? PLATO You...just...seem... Master Mind tightens his grip. MASTER MIND Go on. PLATO ...distracted. Master Mind releases him. MASTER MIND Just with business, my minion. Just with business. I've decided it is time. PLATO You mean? MASTER MIND Yes, we've created our hero, now it's time to give him a little motivation. DA VINCI How do we do that? MASTER MIND To be simply good is not enough. A hero must be driven by an almost relentless desire to right a wrong that can never be corrected. PLATO You mean? MASTER MIND Yes, he must lose someone near and dear to him - his father figure. Gentlemen, it's time for Operation Mentor Kill! EXT. SKY OVER METRO CITY - DAY Titan flies high over and through the city, under bridges, between buildings, etc. He's not really working, just enjoying himself. 71. INT. WOMAN'S APARTMENT - NIGHT A PRETTY WOMAN sits at her makeup table wearing nothing but her bra and panties. Through the reflection in her mirror we see a large window directly behind her. As she applies lipstick we see Titan fly quickly by in the background. After a moment he slowly slides back in view and begins ogling the girl. She sees him in the mirror and quickly covers herself with a robe. Titan tries to hide his face as he zooms off. MOMENTS LATER Titan looks down to see an APARTMENT BUILDING IN RUIN. Emergency lights flash around it as swarms of people run around in chaos. TITAN Man, what the hell happened down there? Wait a sec - He stops in mid-air as he comes to the striking realization. TITAN (CONT'D) THAT'S MY APARTMENT!!! EXT. HAL'S APARTMENT BUILDING - DAY Titan lands in front of the rubble that was once his home. Reporters stand just beyond the police line. TITAN Crap. From the wreckage crawls a dying Pat Morita. TITAN (CONT'D) PAT! Titan goes and kneels beside Pat, holding him in his arms. TITAN (CONT'D) You okay? "PAT MORITA" I'm dying, kid. There is just one last lesson I have for you. It is the most important of all. 72. TITAN What's that? "PAT MORITA" Master Mind did this, you must avenge me. TITAN Master Mind? Why? "PAT MORITA" Because he's evil. You must stop the evil Hal - stop the... Pat's body goes limp. The cameras begin to pop and flash around them. Titan gently lays Pat's body down and stands respectfully over him. The reporters rush over. REPORTER 1 Tighten, Is this the work of Master Mind? REPORTER 2 How will the death of your mentor affect your resolve? REPORTER 3 Was that Pat Morita? Titan walks up to one of the cameras. TITAN This injustice will not go unpunished. Master Mind, if you can hear me, Tighten is coming for you. In the background we see Plato and Da Vinci, DRESSED AS PARAMEDICS, load pat's body onto a stretcher. PLATO ACCIDENTALLY DROPS HIS SIDE. As he bends down to pick it back up, Pat quickly slaps him, then goes back to playing dead. INT. ABANDONED METRO CITY LIBRARY - NIGHT Master Mind and the boys prepare the fortress for Hal's revenge attack. Master Mind is as giddy as a schoolboy. 73. MASTER MIND Alright, people, we don't have much time. Titan should be here any minute, so let's get the lead out. There is a GIANT MOUNTED DEATH RAY in the middle of the hall being tinkered with by Da Vinci. MASTER MIND (CONT'D) How's the death ray coming? DA VINCI Nearly up to full power, sir. MASTER MIND Hum. Let's turn it down a few notches. It's his first time and we don't want to get in a lucky shot, now do we? Plato enters the room. MASTER MIND (CONT'D) Anything on the radar yet? PLATO Not yet, sir. MASTER MIND I see. Well, he must be planning something big. Are the flame androids deployed? PLATO All twelve. Master Mind rubs his hands in anticipation as he sits down on his throne. MASTER MIND Wonderful, wonderful. Plato, Da Vinci, take your places next to me. They move to either side of the chair. MASTER MIND (CONT'D) No slouching. Da Vinci straightens up and sucks in his gut. They remain this way for several long moments. Master Mind occasionally glances at a DIGITAL CLOCK on the wall. Still no Titan. 74. LATER Apparently quite some time has passed. The bold stances have degraded to fatigue. PLATO He's certainly taking his time. MASTER MIND He'll be here. That's the way it works. STILL LATER Master Mind reclines in his chair and taps his metal gauntlet impatiently on the armrest. Plato has squatted down, resting his chin on his hand. MASTER MIND (CONT'D) Unprofessional, that's what this is. No, it's disrespect for the craft. Master Mind rises and begins to pace back and forth. MASTER MIND (CONT'D) Would Uberman have kept us waiting like this? Of course not. He was a pro who knew the score. It's time we spelled out a few things for this Titan. I will not be made a fool of. He storms out of the room. INT. HAL'S NEW APARTMENT - DAY Titan's sitting on the floor in a barren apartment wearing his costume top and some tighty whities. He sips his beer as he watches a basketball game on a tiny TV. Much to his annoyance, there's a KNOCK at the door. TITAN Oh, for crying out loud. He gets up and opens the door. It's Master Mind. MASTER MIND Do you know who I am? 75. It takes a few moments to register, but Titan's suddenly excited. TITAN Yeah, you're Master Mind. Yeah! You're actually the guy I want to see! MASTER MIND Oh, so NOW you want to get down to it. Well, I want to get a few things off my chest first. Master Mind walks past Titan into the apartment. He spins around, pointing at him accusingly with one of his metal fingers. MASTER MIND (CONT'D) Of all the inconsiderate - Do you have any idea how long we waited for you? We're you even planning on coming to me and getting revenge? Titan shuts the apartment door, and turns back toward his guest. TITAN Well, at first I was going to. You know, because that's what I figured I was supposed to do. But then I got to thinking- MASTER MIND (interrupting) -You got to thinking? There's nothing to think about. I'm the villain. I do something bad, you come and get me. TITAN - I got to thinking...what's the point? Master Mind throws up his hands. MASTER MIND Maybe you're right. What's the point? He suddenly notices something in the corner of his eye. He walks over to a futon in the living room. On top of it is a LARGE SACK OVERFLOWING WITH GOLD WATCHES,RINGS AND OTHER VALUABLES. 76. MASTER MIND (CONT'D) What are these? TITAN That's what I wanted to talk to you about. MASTER MIND (baffled) Where did you get all this? TITAN (proudly) Get this: I stole them. MASTER MIND From where? TITAN From all over. You see, once you killed Pat and ruined my other apartment building I was pretty pissed off, so I figured I'd go, find you and kick some ass. Then I thought to myself: "Okay,then what?" I mean, if we were to fight, what would I get out of it? Would I get my apartment back? Would I be able to pay the bills? MASTER MIND Well, what about your mentor? TITAN Tell you the truth? He was kind of a dick. I mean, being a hero is dandy and all, but it's volunteer work. Now you've always had the right take on all this. I mean, when you rob a bank or take over the diamond exchange you get something out of it. I mean, when you don't get caught, which, no offense, isn't very often. And that brings me to what I wanted to propose to you: Who could catch you if I'm by your side? Perplexed by his proposal, Master Mind just stares at Titan awe-struck. MASTER MIND You want to team-up? 77. TITAN You got the brains, I got the brawn. We could even call ourselves that: `Brain' and `Brawn'. Look at this. Titan picks up a piece of POSTER BOARD off the floor and shows it to Master Mind. TITAN (CONT'D) I even designed us some new costumes. The picture is crudely drawn with magic markers and crayons. A big headed man (Master Mind) is standing on a plate of grass in a blue costume with a picture of a brain on his chest. Next to him, is a picture of Titan in a red costume with a black cape, but his chest is mysteriously blank. Titan proudly points to the two figures. TITAN (CONT'D) See, you'd be brain, so you got a little one on your costume, and then I'll have brawn on mine...once I figure out the best, you know, visual interpretation of it. What do you think? MASTER MIND What do I think? Master Mind shakes his head tiredly. MASTER MIND (CONT'D) I think you're probably the biggest idiot I've ever met. I mean, I can't believe you. All your gifts, all your powers, and all you want to use them for is your own financial fulfillment. You know what? Your kind of people make me sick. Titan puts down his drawing. TITAN I worked hard on this. MASTER MIND Oh - gee - I am so sorry! 78. Master Mind looks to Heaven in disgust. MASTER MIND (CONT'D) (under his breath) Of all the people to pick, it had to be this loser. This strikes a cord with Titan. TITAN Now, hold on. You're going a little too far. MASTER MIND I wish your mother said that to your father the night of your conception, they would have saved me a whole lot of heartache. TITAN Hey, I mean it. Master Mind gets right in his face. MASTER MIND Oh, yeah? What are you gonna do? EXT. HAL'S APARTMENT BUILDING - DAY We see Master Mind's body CRASH through the building and land in a DUMPSTER across the street. A car pulls up. The driver's door opens. Da Vinci gets out and runs to help his master. DA VINCI Master! MASTER MIND (O.S.) It hurts. Da Vinci peeks into the dumpster to see Master Mind's body cushioned by a stack of trash bags. DA VINCI What hurts? MASTER MIND It! The overly large henchmen starts to pull his master from the dumpster when they suddenly hear a voice from above. It's Titan peeking through the hole in his apartment wall. 79. TITAN I don't need you, I don't need anybody. I have the power to do and take anything I want. And now, I'm gonna take back everything this city owes me. Beware Metro City, it's time for Titan to collect. Titan shoots up into the air. TITAN (CONT'D) Oh, and from now on - I'M GONNA FLY THE WAY I WANT TO FLY! He takes a sitting position and flies away as if he were piloting an invisible jet. Master Mind climbs out of the dumpster and watches Titan disappear into the distance. DA VINCI How'd the plan go, boss? MASTER MIND I just made myself redundant, old friend. Da Vinci gives Master Mind a whiff. DA VINCI It's not that bad. INT. BANK - DAY Titan, with a happy bounce in his step, enters the bank. The last time he was here he thwarted a robbery. He looks nostalgic. A SECURITY GUARD shyly walks up to him like a kid meeting his TV idol. SECURITY GUARD Morning, Tighten. TITAN Morning. SECURITY GUARD Is there something we can do for you? 80. TITAN Oh, don't bother about me. I'm just here to make a withdrawal. Titan walks across the lobby, drawing stares of admiration from all. A little girl waves to him sweetly. He gives her a good- natured WINK as he heads straight for the vault. The security guard watches him enter and come out with a SACK OF CASH. Sure he must be misunderstanding what's going on, the security guard just stares at Titan as he passes by and out the door. The bank manager comes over to the guard. BANK MANAGER Say, did he just rob us? SECURITY GUARD Not sure. Sort of looks it, don't it? BANK MANAGER Yeah. SECURITY GUARD Should I, you know, stop him? BANK MANAGER Umm...Yeah. As the security guard exits the bank, the manager stares out the window. His eyes suddenly grow wide with terror. The guard's body suddenly smashes through the window, landing at the startled bank manager's feet. BANK MANAGER (CONT'D) (looking down at the guard) He did rob us, didn't he? CUT TO: TELEVISION "A Channel 7 News Special Report." Brad Helms wipes into view. 81. BRAD HELMS "Absolute power corrupts absolutely." When Lord Acton stated that, in a letter to Bishop Mandell Creighton in 1887, no one thought much about it, but today Metro City is reeling from that very prophecy. Tighten, who many thought of as our savior, has turned his back on the cause of justice. CUT TO: TITAN BEING EVIL - MONTAGE EXT. DIAMOND EXCHANGE - DAY Titan flies through the window of the building. He emerges seconds later laughing with his shirt full of booty. EXT. CITY STREET - DAY A woman screams from the window of a BURNING BUILDING. Titan flies up to her, grabs her fur coat and zooms off again, leaving the woman behind, slightly confused. EXT. OUTSIDE MARKET - DAY Titan steals a little boy's lollipop and gooses his mother. EXT. CITY STREET - DAY Dozens of people run through the streets apparently to get out of a downpour. We cut to the top of a building and see Titan ZIPPING UP HIS PANTS and laughing. INT. ABANDONED METRO CITY LIBRARY - NIGHT Master Mind paces back and forth in front of Plato and Da Vinci. PLATO I don't understand it. He seemed to have every characteristic we were looking for in a superhero. MASTER MIND Well, there's no use crying about it now, we must take action. I'm not going to play second fiddle to that crass buffoon. We must destroy Tighten. 82. PLATO It won't be easy. Uberman had a sense of decency and genuine love for the people. That was his weakness and was easily used against him. MASTER MIND Yes, but he possesses the same flaws present in Uberman's DNA - copper. It's like Benjamin Franklin always said: "If something works don't dick with it." EXT. BAR - DAY It looks like a war zone passed through here. Smashed police cars and debris lay everywhere. This seems to be the only building left untouched. INT. BAR - DAY A very tipsy Titan is sitting at the bar, looking deep into the bottom of his beer glass for answers. TITAN I can have anything I want. I'm like a god. The BARTENDER just listens as he wipes down a glass with a dirty rag. TITAN Point to any woman in this bar. I could have her in a second. He follows the bartender's gaze to THE ONLY OTHER PERSON THERE - A passed out, MIDDLE AGED HAG OF A BARFLY. TITAN (to Old Barfly) Hey, you wanna get with this? BARTENDER Buddy, what do you want? Titan carefully considers this for a moment. TITAN What do you want? That's the question, isn't it. I mean, what do you want when you can have everything? (MORE) 83. TITAN(cont'd) I suppose what I really want is to never be forgotten again. I want to do something that can never be cast aside or one-upped. I want a - what's it called? - A legacy. I want a legacy. Yeah, that's it. I like the sound that. BARTENDER I meant, what do you want to drink? TITAN Oh. EXT. BAR - LATER Titan stumbles out of the bar, carrying a large sack of money. MASTER MIND (O.S.) Your time has come to an end, Titan! He looks up to see Master Mind suddenly standing before him. TITAN What? MASTER MIND There can be only one master criminal in this city - and it's me. TITAN Really? Titan melodramatically throws up his arms. TITAN (CONT'D) I guess I should leave town then, huh? MASTER MIND I have a better idea - NOW! Two floors up Da Vinci releases a rope. A COPPER CAGE, like the one that caged Uberman, drops down on top of Titan. Titan nonchalantly surveys the cage. He walks to the bars, tries to pull them apart but can't. MASTER MIND (CONT'D) That's copper my good man. Your one weakness. (MORE) 84. MASTER MIND(cont'd) For all your amazing gifts of brawn you are no match for my intellect. Titan thinks for a moment. Suddenly, he starts to SPIN like a human top, DRILLING HIMSELF INTO THE STREET BELOW. As he disappears beneath the surface, we see a shocked look on Master Mind's face until Titan suddenly explodes out from under the street in front of him. Master Mind stares up at him, dumbfounded. Titan makes like he's going to strike him down, but stops. TITAN You know what? You're nothing but a bug. Not even worth my effort. He turns his back to Master Mind and continues down the street. Plato makes his way from the shadows to join his master. They watch Titan shrink into the distance. MASTER MIND He's not as dumb as I thought. PLATO I guess not...Funny, though. MASTER MIND What's funny? PLATO Funny Uberman didn't think of the same thing. EXT. HIGH ABOVE METRO CITY - DAY As Titan flies, he looks down at the rooftops of the city below. Suddenly, something catches his attention. HAL That's it! He stops, hovering in place as he looks down below. The buildings, which make up the heart of downtown Metro, are in a PERFECT TRIANGLE with a long strip of street leading up to it. It sorta looks like a bowling lane. 85. HAL Hello, Legacy. EXT. KINGPIN BOWLING - DAY Vinnie and his goons come running out as the hear a COMMOTION. They look up to see Titan ripping off THE GIANT BOWLING BALL from the top of the establishment. VINNIE Hey, that's my ball! INT. ROXANNE'S APARTMENT BUILDING - DAY Roxanne enters the building's elevator. Just before the door closes an ELDERLY WOMAN slides in. ELDERLY WOMAN That was a close one. Sixth floor, please. Roxanne smiles and goes to press the button. The elderly woman suddenly pulls out a SPRAY CAN, shooting a MYSTERIOUS-LOOKING MIST into Roxanne's face. She falls to the floor unconscious. INT. ROXANNE'S APARTMENT - DAY Roxanne awakens, finding herself tied to a chair in her living room. We hear NOISE from a TV in the background as she tries to adjust her vision. Slowly, the blurry figure before her becomes clear. It's Master Mind. He sits on her Lazy-Boy, reading what looks to be some kind of JOURNAL. MASTER MIND Wow, I always thought Uberman was your first superhero - but it looks like our little Roxanne dated a linebacker in college. ROXANNE That's my diary. MASTER MIND So it is. 86. ROXANNE It's personal. MASTER MIND Well, then I wouldn't leave it in your underwear drawer for just anyone to find. He throws the diary over his shoulder. ROXANNE What do you want? MASTER MIND I need your help. ROXANNE So you knock me out and tie me to a chair? MASTER MIND You're not going to like what I'm about to tell you. As she tries to shake off her headache from being knocked unconscious, Roxanne spots something on the TV. ON TELEVISION Brad Helms is huddled behind a van. BRAD HELMS It's chaos here in city square as city police - Behind him, Titan picks up a POLICE CAR and throws it at a PADDY WAGON. Both vehicles EXPLODE on impact. BACK TO SCENE ROXANNE He's really out of control. MASTER MIND Tell me about it. As if finally realizing something, Roxanne looks back at Master Mind. ROXANNE I should have known. You have something to do with this, don't you? - With Titan turning evil. 87. MASTER MIND Well, the evil thing he did by himself. My goal was to give MYSELF purpose by creating an intellectual sparring partner. ROXANNE (confused) You're talking like you made him. MASTER MIND And they call me Master Mind. ROXANNE Let me get this straight. You missed getting your ass kicked, so you made a new guy to kick your ass. That's pathetic. MASTER MIND In hindsight... Roxanne turns back to the TV to see a group of POLICE OFFICERS open fire on Titan. The bullets just deflect off his chest. ROXANNE And his powers, they're just like Uberman's. Why would he have his powers? MASTER MIND (almost ashamed) I had some left over from something. I infused him with it. ROXANNE YOU DID WHAT!? Driven by rage, she struggles to tear out of her bonds. She finally relents, giving Master Mind a look fueled by pure hatred. MASTER MIND Yeah, that's why I decided to tie you up. ROXANNE You did all this because you wanted purpose? MASTER MIND He seemed nice. 88. TELEVISION Titan is standing on top of a destroyed police car. He waves for the camera to zoom in on him. TITAN Closer. I want to show the people my real face. He pulls off his mask, revealing himself as Hal Stewart to the public for the first time. TITAN (CONT'D) Recognize me? BACK TO SCENE ROXANNE Hal Stewart. He's the guy we thought saved that woman and kid. Turned out he was just trying to save his own ass. MASTER MIND Yeah, good to know - NOW! TELEVISION Titan throws the mask over this shoulder and hops off the car. TITAN That's right, I'm really Hal Stewart. Former hero and bowling teacher at Kingpin's Bowling. BACK TO SCENE Roxanne turns to Master Mind, condescending him with her eyes. ROXANNE You picked a bowler to give super powers to? MASTER MIND It's a modest profession! TELEVISION 89. TITAN With my new found power, I've recently started to wonder what sort of legacy I should leave. Should I be a hero? I tried that once before - even saved a lady and her baby from being squashed. I was treated like a god until everyone started to shit on me - Okay, so what if I didn't "purposely" save them! He walks over and puts his hand on a large circular concrete shape just off camera. TITAN Well, I'm going to make something that can't be taken away from me. I'm going to create a permanent monument to my greatness. One that won't be so easily forgotten or erased. The camera pulls back revealing THE GIANT CONCRETE BOWLING BALL from Kingpin's. TITAN I intend to create a new category in the Guinness Book of World's Records by rolling the biggest strike in the history of bowling. He grabs the camera and points it to the DOWNTOWN BUILDINGS. We realize they are PERFECTLY ALIGNED IN BOWLING PIN FORMATION. TITAN My thanks to the city planning commission. This wouldn't have been possible without them. Titan grabs the camera so it's pointing back at him again. TITAN Tell your friends and family to tune in right here to this station at noon tomorrow. BACK TO SCENE ROXANNE My god, he's nuts. That'll destroy the whole business triangle. 90. Master Mind seems to be contemplating something - something bad. ROXANNE What? MASTER MIND My lair is in the direct path of the ball. ROXANNE Oh, real nice. Wouldn't want anything to happen to your hideout, would we? MASTER MIND You don't understand. I have certain equipment that's - that's highly unstable. ROXANNE What do you mean? MASTER MIND I sort of have a hydrogen reactor, okay? ROXANNE A HYDROGEN reactor? MASTER MIND It's experimental - only one in the world...Well, how do you think I power all my inventions? Someone like me can't pay for electricity. The bills would be outrageous. ROXANNE A REACTOR? MASTER MIND It creates 100 times the output of a nuclear one...If destroyed it could... ROXANNE - Vaporize the entire city! MASTER MIND (proudly) Pshaw...the whole eastern seaboard, actually. That little baby is amazing. I'm quite proud of it. (MORE) 91. MASTER MIND(cont'd) (off her deadpan reaction) I mean...we'd better find a way to stop him. Master Mind thinks a moment. MASTER MIND Did Uberman have a hideout? ROXANNE What? MASTER MIND A cave, a solitary fortress of some kind. C'mon, all heros have a place to hang their capes up in. Roxanne, it may be our only chance to find something, a clue, anything that could give us a fighting chance. ROXANNE It's under his house. MASTER MIND Whose house? Roxanne can hardly believe what she's telling him. ROXANNE Wayne Scott's. Master Mind shoots up out of his chair. MASTER MIND Wayne Scott? Uberman was Wayne Scott!? Wayne Scott, the wealthy philanthropist? But he disappeared - ROXANNE (interrupting) He disappeared just over two months ago when you killed him. Not only did you rid the world of a hero, you killed a kind, noble, generous man. Perhaps ashamed, the super villain hangs his head. Master Mind walks behind Roxanne and undoes her bonds. Rubbing her wrists, she watches him as he walks over to the door. 92. ROXANNE (CONT'D) Looks like you got what you always wanted. Uberman is out of the picture and Metro City is doomed. He grabs the door knob and stops, considering her words. MASTER MIND "Metro City doomed." You know, I never thought I'd say something like this, but here it goes - He slowly turns to her, CUE HEROIC MUSIC. MASTER MIND (CONT'D) Not if I have anything to say about it. EXT. WAYNE SCOTT'S MANSION - NIGHT Master Mind stands before the huge, Gothic structure in awe. MASTER MIND Such a dark place for one such as you. I wonder, underneath your noble deeds, what inner demons drove you to your endless crusade for justice? He walks to the front entrance. The double doors have been sealed shut with boards and nails. Master Mind begins to tear them off with his metal hand. INT. WAYNE SCOTT'S MANSION - NIGHT The doors opens. A beam of moonlight immediately pierces the darkness, forming an illuminated path into the heart of the manor. Master Mind enters. Covered in dust and cobwebs, the hall looks like a gigantic crypt. MASTER MIND Good lord, man. You've only been dead for two months. Master Mind walks, coming to a gigantic painted PORTRAIT OF WAYNE SCOTT. He stops to reverently admire the image of his fallen foe. 93. MASTER MIND (CONT'D) A disguise so simple, it's ingenious. No wonder I never caught on. Besides the Armani suit, there's nothing to hide the fact that this is the same person as Uberman. In the picture, he's even standing in the same cheesy, heroic pose with his fists on his hips. MASTER MIND (CONT'D) Two lives, yet in both you were an ideal. Perhaps it was you who was victorious in the end, old friend. A BONGING sound suddenly bellows through the dark halls. Master Mind comes to a grandfather clock standing next to a gigantic BOOKCASE. On the twelfth bong it falls silent. Master Mind begins to slide it across the floor until he hears a loud CLICK. The bookcase slides into the wall, REVEALING A HIDDEN PASSAGE. MASTER MIND (CONT'D) I'll miss how predictable you were. The passage way leads Master Mind to a WORKING ESCALATOR. Master Mind gets off the escalator to see a long hallway with stone walls. He begins to hear strange SOUNDS, almost like MUFFLED SCREAMS, coming from a doorway at the end of the hallway. Master Mind starts walking towards it. As he steps closer, he begins to notice a light cracking through the bottom of the door. MASTER MIND (CONT'D) Hello? Anyone here...besides..all the BIG MEN who are with me now? Nothing. MASTER MIND (CONT'D) (to himself) What's the worst you're gonna find? (MORE) 94. MASTER MIND(cont'd) The man was a boy scout, not a serial killer. He opens the door to his immediate amazement. It's some kind of screening room. A PROJECTOR shoots an image onto A DIRTY WHITE SCREEN hanging on the wall. BEER CANS litter the floor; a table in front of a ripped-up couch is covered in discarded snack goods; and a Kiss Pinball machine stands in the far corner next to a CLOSED DOOR. Master Mind turns his attention to the action on the screen. SCREEN A woman dressed in a leather DOMINATRIX OUTFIT is whipping an overweight man lying on a swing-like device with his butt sticking out. DOMINATRIX IN FILM YOU ARE A WORM! She whips him three times. The man CRIES out in pain. FAT MAN IN FILM PINEAPPLE!!! PINEAPPLE!!! Master Mind's eyes are transfixed on the disturbing imagery. The door by the pinball machine suddenly swings open. WAYNE SCOTT, dressed in raggedy sweats, steps into the room carrying a CAN OF BEER and a bowl of JIFFY-POP. Master Mind cannot believe his horrified eyes. MASTER MIND Ahhhhhh! Wayne Scott is just as startled. WAYNE SCOTT Jesus! He drop his drink and snack to the floor. The two men stare at each other as they struggle to regain their normal breathing patterns. Wayne Scott walks over to the couch, brushes off a thick layer of chip crumbs, and sits down. WAYNE SCOTT (CONT'D) What the hell are you doing here? 95. MASTER MIND I might just ask you the same question. I had thought I incinerated you. WAYNE SCOTT You scared the bejesus out of me. How'd you figure out I was still alive? Wait, how do you know my identity!? MASTER MIND Roxanne told me. As for your ruse, I forgot to line the bottom of the copper cage - Somebody pointed that out to me recently. Figured if they could do it, so could you. But one thing I couldn't figure out - WAYNE SCOTT The skeleton? Something I "borrowed" from a medical school a few months before. MASTER MIND A few months? How long had you been planning this? WAYNE SCOTT I always planned to retire - eventually. I mean, come on, you can't do this sort of thing in your fifties. You'd just look ridiculous. The pieces of the puzzle appear to be coming together in Master Mind's head. MASTER MIND I see it all so clearly now. INT. MASTER MIND'S HYDROFOIL - FLASHBACK Master Mind and his minions cover their eyes as the observatory explodes. MASTER MIND (CONT'D - V.O.) You must have done it just seconds before the observatory exploded. 96. INT. OBSERVATORY - FLASHBACK Similar to what Titan did, Uberman bores out from under the cage. MASTER MIND (CONT'D - V.O.) You bore out from under the cage. Then, using your Uber-Speed, - EXT. OBSERVATORY - FLASHBACK Running in a blur-like haze, Uberman screeches to a halt in front of some bushes. MASTER MIND (CONT'D - V.O.) - you made your way to safety, where you had the skeleton safely hidden away somewhere. EXT OBSERVATORY - SKY - DAY Uberman soars high above the clouds. He looks down at the observatory, which is a mere speck in the distance. MASTER MIND (CONT'D - V.O) (CONT'D) Then you must have flown to a safe distance and waited for the explosion, then... Just as the observatory explodes Uberman aims and throws the SKELETON like a javelin. It soars through the air like a missile, tearing through the flames of the explosion, and crashing right into the windshield of Master Mind's hydrofoil. END OF FLASHBACK Wayne stares at Master Mind, clearly impressed. WAYNE Man, you ARE smart. MASTER MIND But why fake your death? Why go through all of it? You could have just quit. WAYNE SCOTT But the responsibility would still be there. (MORE) 97. WAYNE SCOTT(cont'd) A cop can retire and stop handing out speeding tickets - but people expect more from superheroes. I tell you, a volcano couldn't erupt in Zimbabwe without everyone expecting me to do something about it. I figured, out of sight, out of mind. MASTER MIND And Wayne Scott? Why did he have to disappear? WAYNE SCOTT Both of my lives have so much baggage. It's time for new baggage, you know? Master Mind's is absolutely flabbergasted. MASTER MIND I just can't believe it. This whole time you've been in hiding while a force of great evil is tearing your city apart? Wayne rises to his feet, waving his hands for Master Mind to say no more. WAYNE SCOTT I don't want to hear about it. That's why I don't have a television in here to remind me of all the things I SHOULD be doing. Hell, I could get a wife to do that. MASTER MIND There's a demented supervillain out there about to destroy our - I mean, your city. Wayne shrugs indifferently. MASTER MIND You're really going to do nothing? WAYNE SCOTT Good and evil have a way of balancing themselves out. If this guy is as bad as you say, somebody will rise up to fight him. It's just the order of things. You found me, didn't you? 98. Wayne puts a condescending hand on Master Mind's shoulder. WAYNE SCOTT (CONT'D) I know it's hard, but you'll find someone else someday. He then starts walking to the door. MASTER MIND You're the only one who can stop him. Wayne turns around. WAYNE SCOTT Couldn't if I wanted to. Gotta a plane to catch. MASTER MIND A plane? WAYNE SCOTT Going to Barbados for a little change in climate. Now, if you'll excuse me, I got to go pack. He reads the still defeated look on Master Mind's face. WAYNE SCOTT (CONT'D) You were a good foe. I'm sorry if I've let you down. If it makes a difference, you were the best foe a hero could ask for. MASTER MIND Not smart enough to come up with a full-proof trap. WAYNE SCOTT Well, you did almost have me when you figured out my weakness was copper. Now that made me sweat a little. Took me way too long to drill out from under that cage. MASTER MIND I got lucky. WAYNE SCOTT Anyway, it's a good thing for my sake that I could always count on you for an out. 99. MASTER MIND (suddenly confused) What do you mean? WAYNE SCOTT C'mon, we always threw each other a couple of bones. You would always leave me an out in one of your `full-proof' traps, and I'd never had you incarcerated at a penitentiary that you couldn't eventually escape from. It kept our little game going. Master Mind seems deflated. MASTER MIND Game? - Was that all this ever was to you? You know, I was trying my best every time I fought you. Those `outs' as you call them were unintentional. WAYNE SCOTT Oh. MASTER MIND I guess I was never really a match for you, was I? Wayne shrugs. MASTER MIND (CONT'D) (thoughtfully) Then how can I expect to be one for Titan? A beaten man, Master Mind heads for the door, but stops and turns around. MASTER MIND (CONT'D) What about Roxanne? Wayne unleashes an exhausted sigh. WAYNE SCOTT I think we both got what we wanted out of our relationship. She got a career out of me, and I got plenty of other things out of her. But I'm ready to move on to greener pastures. 100. Master Mind's steel hand clinches into a fist at his side. Wayne's oblivious to this. MASTER MIND I guess I wasn't the villain I thought I was, and you...you weren't the hero I thought you were. He turns to make his exit when he suddenly sees ROXANNE STANDING IN THE DOOR FRAME. Wayne is almost at a loss for words. WAYNE SCOTT Roxanne! How long have you been... ROXANNE Long enough. Roxanne looks at Master Mind. ROXANNE (CONT'D) Don't you have something else you can go do? Master Mind leaves Roxanne and Wayne facing each other in silence. EXT. ANOTHER BAR - DAY Titan emerges with Brad and Frank. He's holding a BEER CAN and a bag of PORK RINDS. TITAN Alright, I want this whole thing to look ESPN professional, understand? A distant MECHANIZED RUMBLE can be heard. The noise rises, signaling the approach of something powerful. Titan and his crew walk out to the center of the plaza as the sound becomes almost deafening. A TANK TRACK as it moves over the street. We PULL BACK to see a whole line of TANKS rolling along the street. PLAZA From the five streets branching off the plaza, a dozen tanks roll toward Titan. 101. Titan turns to Brad and Frank. TITAN (CONT'D) You guys are about to get some good footage. I might need a little room, though. Brad and Frank look at each other and run to take cover behind a nearby building. Meanwhile, Titan nonchalantly sips from his beer as the tanks begin to surround them. FEEDBACK belts out of one of the tank's loudspeaker's, causing Titan to do a mock wince. TANK LOUDSPEAKER Titan, we have orders from the city of Metro to take you into custody. If you do not give your self up willingly, we will be forced to open fire. There's a long pause as no one says anything. TANK LOUDSPEAKER What is your answer? Titan takes a sip of his beverage and UNLEASHES A GIGANTIC BURP - The shockwave of which sends several of the tanks flying into a nearby building. Two of the remaining tanks close in on the villain. Both have him dead to rights at point-blank range with their massive guns. Titan sets down his beer, then calmly plugs a fist into each barrel. They FIRE. The FORCE OF THE BLAST SENDS THEM BOTH FLYING IN OPPOSITE DIRECTIONS where they CRASH into nearby buildings. Titan bends down and pick his beet back up. TITAN (to beer) Miss me? Titan is suddenly bombarded by a massive barrage of machine- gun fire. The force sends him flying into the windshield of a nearby car. 102. He looks up to see an APACHE ASSAULT COPTER. It's nose- mounted GATLING-GUN is turning toward him. Titan gets up to his feet and looks down at his beer can. The bottom of it was blown apart in the blast. TITAN (CONT'D) Didn't mean to get you involved in all of this. He stared daggers up at the helicopter pilot just as the gun gets a bead on him. TITAN (CONT'D) Hey, man! You killed my suds! Titan throws the can up and slaps it with the palm of his hand. It flies with so much force it knocks the helicopter blade clean off. The rest of the Apache crashes to the street like a car dropped off a building. TITAN (CONT'D) That's one was for you, beer. Titan salutes the wreckage and walks away to find Brad and Frank still hiding behind the building. TITAN Guys, please tell me you got that last bit. BRAD HELMS Huh? TITAN You're kidding me. I give you my sexiest moves and you mean to tell me it was for nothing? BRAD HELMS We were afraid something might hit us. TITAN Looks like I've given the story of the century to the wrong man. He thinks about this for a moment, then it hits him. 103. TITAN Wait. What about that other reporter. Blond. Not so lumpy on the topper half, but killer legs. BRAD HELMS Roxanne. You want Roxanne. She's a much better reporter than I am. You want her. TITAN Where can I find her. FRANK We're actually not supposed to give out that sort of information. BRAD HELMS 1314 Mockingbird Lane. I believe she lives in a penthouse. TITAN You've been very helpful. He tosses Brad over his shoulder like a discarded ice cream cone. In the faint distance we see him splash down in the middle of the Metro City river. INT. ABANDONED METRO CITY LIBRARY - DAY Master Mind, pacing anxiously as Plato and Da Vinci pack boxes. Obviously Master Mind is going on the lamb. MASTER MIND Hurry, we must be on our way as soon as possible. DA VINCI Master, why must we flee? MASTER MIND I told you, Titan is too powerful. If he's set on destroying us, there's precious little we could do about it. DA VINCI Where are we going? 104. MASTER MIND To another city, someplace with a shitload of superheroes to fight. We'll start over, we'll go back to doing what we do best. PLATO With our tails between our legs? The old Master Mind would never have let this comment slip by, but as we have seen, he's not the same man. MASTER MIND Plato, do you have a better plan?! Master Mind's cell phone rings. He turns in shame from his men and answers it. MASTER MIND (CONT'D) Hello...Roxanne? INT. ROXANNE'S APARTMENT Roxanne paces back and forth on the phone. ROXANNE What are you going to do about Tighten? INTERCUT between Master Mind and Roxanne on phone. MASTER MIND Right now I'm packing, later I'll have a snack on the train. ROXANNE You're running away? MASTER MIND In a word - yes. ROXANNE You created this monster... MASTER MIND I didn't create this - the god's of irony did and I am eating the crow I so richly deserve. ROXANNE There's no time for self pity. 105. MASTER MIND I'll make the time. Roxanne can't believe what she's hearing. MASTER MIND (CONT'D) You can leave with us. You'll be safe. ROXANNE I'm not going anywhere. MASTER MIND Will you listen to me, no one can stop him. ROXANNE You have to try. The city needs your help. MASTER MIND I'm afraid you have an inflated opinion of me. ROXANNE What the hell's happened to you? The Master Mind I knew would never have run from a fight even though he knew deep in his heart that he didn't have a chance in hell of winning it. It was your best quality. You need to be that man right now...I... MASTER MIND What? ROXANNE (heart felt) I believe in you. Master Mind is taken aback, in a good way. But he catches himself before the words swell his heart. MASTER MIND Sweet words, but that man is dead. Please, Roxanne, just come with me. ROXANNE No...I guess you are a coward after all. Suddenly, there's a loud crash. 106. Roxanne looks up to see a huge hunk of her ceiling has been completely ripped off. Titan is flying above, holding the debris as casually as if it were a paper plate at a barbecue. He looks down at her and smiles. TITAN Man, have I got a story for you. Master Mind can hears Titan's familiar laugh from his side of the line. MASTER MIND Roxanne? Roxanne? EXT. KINGPIN BOWLING - DAY Titan is standing in front of the bowling alley, trying to decide on an appropriate pose for the occasion. TITAN What pose would be best? The corny folded arms thing? He demonstrates, arching his chin proudly in the air. TITAN Or maybe on the hips, like this. It's the classic Superman pose, only not as masculine. TITAN No, makes me look like a flamer pirate. As Titan starts to fix his hair in the window, Frank pretends to fix the lens on his camera as he speaks to Roxanne. FRANK (whispering) Shouldn't we be making a run for it right about now? ROXANNE (whispering) The guy can outrun bullets. I don't think either one of us is in that kind of shape. TITAN She's right, Frank. 107. Frank looks up, stunned that Titan could have possibly heard him. TITAN Also got super hearing. I promise not to keep the both of you long, but you'll thank me when this is all over. Frank and Roxanne exchange helpless expressions. INT. ABANDONED METRO CITY LIBRARY - DAY Master Mind reverently stares up at the painted portrait of his father. MASTER MIND Dad, it's me... (he looks around to make sure no one can hear) ...Bubsy. I know we haven't talked in a while, and I'm sorry. It's been a little crazy trying to live up to a legacy. The painting's menacing stare seems to reach into his very soul. MASTER MIND Anyway...You raised me to be the worst that I could possibly be. And I've tried to live up to that as best as I could - even dropping out of dentistry school like you wanted me to. But I'm about to do something now that would really piss you off. I'm going to go against everything you ever taught me. I hope...I hope that maybe you'll look down at what I'm about to do as not so much a good deed, but more like the outright defiance of a hateful and ungrateful, son. If you could do that, then maybe - in your own little way - you could - for probably the first time - find a reason to be proud of me. He looks back up at the picture. Is it our imagination, or does the painting's stare suddenly seem even angrier? 108. MASTER MIND Well...either way, you're probably going to see me real soon. (calling over his shoulder) Men? Plato and Da Vinci suddenly stop what they're doing and look up at him. PLATO AND DA VINCI Yes Sir? MASTER MIND Stop packing. Our work is not finished here. PLATO AND DA VINCI YES SIR! TELEVISION A news report shows an aerial shot of Titan setting the giant ball down in the middle of a vacant city street. REPORTER We interrupt your regular afternoon programming to show you live footage of a potential dangerous situation in downtown Metro. The former hero knows as Titan is placing what appears to be a giant ball... INT. ABANDONED METRO CITY LIBRARY - CONTINUOUS Da Vinci stops in front of a television set, seeing the news report in progress. REPORTER Hold on...It appears our own Roxanne Ritchi is somehow at the scene. We now go to her with a live report. DA VINCI Sir, I think you should see this! CUT TO: 109. EXT. CITY STREET - DAY Roxanne is standing in front of a camera with a mike in her hand. ROXANNE I'm here with the cause of the destruction in Metro City. He has kidnapped me and a cameraman to chronicle what he refers to as the creation of a monument to his invincibility and overall "Asskickiness." He will use this giant concrete bowling ball to play the largest game of bowling ever using the buildings of downtown Metro City as his pins. Titan suddenly steps into the shot. TITAN And I'm going for the biggest strike ever. He leans into the camera. TITAN And you, Metro City, have a ringside seat as I cement my name in the anal of history. ROXANNE Annals. TITAN What? ROXANNE Nevermind. EXT. CITY STREET - MOMENTS LATER Titan holds up the massive bowling ball, lining up his shot. TITAN (in quiet professional bowler announcer voice) Like Tiger before him, a young savior has come to raise a sport from the ashes. Rookie Hal Stewart, a young man with a dream, realizing that dream here today, folks. (MORE) 110. TITAN(cont'd) One might click there heels and say "There's no place like home" upon finding themselves in such a fantasy. Well, Hal looks very much at home right were he is - with a ball in hand and glory in his sights. INT. METRO CITY LIBRARY - CONTINUOUS In the bowels of Master Mind's hideout, the HYDROGEN REACTOR glows and HUMS MENACINGLY. BACK TO SCENE Roxanne just stand helpless as Frank films away. ROXANNE Hal, I know everyone treated you like shit, but you don't have to do this. TITAN You're right. I don't HAVE to do anything. Isn't that cool? Titan lines up his shot. TITAN Here's one for the record books! Titan flies a few feet and rolls the ball down the main street. ROXANNE Her face is utter horror as she watches the inevitable destruction of Metro City. As the ball rolls - it demolishes everything in it's wake; cars, street lamps - windows shatter as the giant concrete sphere brushes along side buildings. TITAN He smiles in anticipation and uses "body English" to direct the ball. GIANT BOWLING BALL POV It's nearly halfway to its target. ROXANNE 111. She closes her eyes. Titan's smile fades. He looks around as if he hears something we don't. About two hundred feet in front of the first building a GIANT SPIDER WEB flies across the path of the ball, creating a defensive barrier. An enormous letter "M" is etched in the web's center. TITAN (CONT'D) What the...? The ball breaks through the web, but it's speed is greatly reduced. FRANK Look, what's that flying in the air? We suddenly see MASTER MIND FLYING OVER THE ROLLING BALL IN A JET PACK. He quickly pulls out his goo gun and starts laying down a path of sticky plasm to stop the destructive sphere's path. MASTER MIND C'mon, slow down Master Mind looks down to see the meter of the gun close to empty. MASTER MIND C'mon. The ball slows drastically then starts rolling to the side. It heads off an embankment and rolls harmlessly into a CANAL. MASTER MIND Gutterball! TITAN He's furious to say the least. TITAN YOU! Master Mind gives him a mocking grin. MASTER MIND Bowling? What other trailer park sports can you play? 112. TITAN You are becoming a real pain in my ass. I should have done this a long time ago. Titan lunges at his tormentor. Master Mind hits the BOOSTER on his jet pack and heads back toward the other side of the city with Titan in hot pursuit. MASTER MIND (CONT'D) (into walkie talkie) Plato, Da Vinci. Secure Roxanne, he's falling for it. ELSEWHERE A flustered Titan lands. He begins searching the city streets, but Master Mind is nowhere in sight. He turns upon hearing an EEKING sound to his left. Sitting on the ground is a CHIMPANZEE wearing a strange collar. It smiles at him. TITAN What the hell? From behind, Titan is immediately set upon by five more RADIO CONTROLLED APES. TITAN (CONT'D) GODAMNIT! The critters bite hop and hit Titan. As soon as he throws one off two more jump him. Titan breaks free and with his mighty breath blows them across the street into a fruit stand. With Titan out of their sight they begin to attack the fruit. MASTER MIND He's a block away frantically hitting his remote. MASTER MIND Shit! Stupid monkeys and their fruit. Titan flies away from the mad monkeys and lands to find Master Mind sitting on the ground wrapped in a long cape with only his head sticking out. 113. TITAN (CONT'D) No more games. Titan FIRES HIS LASER VISION AT MASTER MIND's CHEST. Master Mind pulls the cloak away to reveal a FIRE HYDRANT. Titan's EYE LASERS burn through the hydrant releasing a high pressure stream of water. Master Mind uses the last remote which dumps two tons of CEMENT mix into the truck. The crowd, police and news crews move in closer when Titan doesn't emerge. Master Mind drops his last remote and walks toward the truck cautiously. MASTER MIND Could it really be that easy-- - BOOM - The back of the truck explodes, throwing dust and concrete everywhere. When the dust clears we see and enraged Titan. MASTER MIND (CONT'D) Didn't think so. As the villain walks toward him, he pulls back his fist to give Master Mind the killing blow. TITAN If you don't mind, I'm going to punch trough your face now. Preparing himself for the end, Master Mind shuts his eyes as a SUDDEN GUST OF WIND BEGINS TO PICK UP. AS Titan goes to strike, a BLURRY FIGURE RUNS IN AND SNATCHES MASTER MIND OUT OF THE AWAY. Stunned, Master Mind begins to feel around his body as if to make sure everything's still in place. MASTER MIND I'm alive. He turns to see UBERMAN standing next to him. MASTER MIND Uberman? 114. The terrified bystanders start to notice the figure standing next to Master Mind. BYSTANDER 1 It's Uberman! BYSTANDER 2 Uberman's alive! BYSTANDER 3 We're saved! As the CROWD CHEERS, A confused Master Mind turns to Metro City's newly resurrected champion. MASTER MIND I thought. UBERMAN So did I. He puts a hand on Master Mind's shoulder. UBERMAN Thank you, old enemy. MASTER MIND For what? UBERMAN Showing me the error of my ways, Showing me I'm meant to be this city's savior, showing me that, while we can try, there is no running away from our true destiny. With that, UBERMAN IS STRICKEN BY A LASER BLAST, INSTANTLY TURNING HIM INTO A CHARRED HUMAN SKELETON. Master Mind turns to see Titan smiling with his STILL SMOKING EYES. TITAN Oh...Did I interrupt something? Master Mind turns to run, but, suddenly Titan is before him. TITAN Where you going, buddy? Titan grabs Master Mind by the collar and throws him across the street into a parked car. 115. TITAN (CONT'D) Welcome to Paintown. Population: you. Master Mind manages to stand on shaky legs. He seems in a daze, unable to move. Titan flies up in the air. TITAN (CONT'D) Time to finish this. With his fist front and center, Titan speeds toward Master Mind. He's like a human torpedo, coming in for the killing blow. Master Mind comes to his senses and puts up his hands. MASTER MIND WAIT!!! Titan screeches to a halt and stops just in front of him like an old Warner Bros cartoon. TITAN What? MASTER MIND Quick joke - What's the capital of Thailand? TITAN Huh - I don't know. MASTER MIND It's bang cock! In a sudden surge of strength, MASTER MIND PUNCHES TITAN IN THE GROIN. The once mighty man instantly drops to his knees, searching, with tears in his eyes, for the proper word to express the pain suddenly surging through his member. TITAN (CONT'D) Ow. Baffled, he looks up at Master Mind's hand and sees his gauntlet is now made ENTIRELY OUT OF COPPER. MASTER MIND So, I guess pennies are good for something. 116. He punches Titan in the face, knocking him out cold. Master Mind looks down on Titan with more than a little pride. Suddenly he hears something behind him. He spins to see the crowd making a strange noise - APPLAUSE. Roxanne comes up to him. The crowd starts to go wild and cheers for Master Mind. He's not sure what to make of it. ROXANNE Pretty strange, huh? MASTER MIND They're cheering for me. ROXANNE You saved them. You saved everybody. How's it feel? Master Mind looks at the smiles all around him. He begins to well up a little. MASTER MIND It's a...it's nice, you know? I usually don't get a lot of feedback. (whispering) But I also kind of caused all this. What happens when they find that out I was the cause of some of this? Roxanne looks at the cheering crowd, then back at Master Mind. ROXANNE What they don't know won't hurt them. MASTER MIND I guess that is all in the past. ROXANNE You're the hero. MASTER MIND I don't think I'd go that far...I mean I just...er... ROXANNE Master Mind? 117. MASTER MIND Yes?

The aim of this assignment is to have you do TCP socket client / server programming using I/O multiplexing, child processes and threads. It also aims at getting you to familiarize yourselves with the inetd superserver daemon, the ‘exec’ family of functions, various socket error scenarios, some socket options, and some basic domain name / IP address conversion functions. Apart from the material in Chapters 1 to 6 covered in class, you will also need to refer to the following : the exec family of functions (Section 4.7 of Chapter 4) using pipes for interprocess communication (IPC) in Unix error scenarios induced by process terminations & host crashes (Sections 5.11 to 5.16, Chapter 5) setsockopt function & SO_REUSEADDR socket option (Section 7.2 & pp.210-213, Chapter 7) gethostbyname & gethostbyaddr functions (Sections 11.3 & 11.4, Chapter 11) the basic structure of inetd (Section 13.5, Chapter 13) programming with threads (Sections 26.1 to 26.5, Chapter 26) Overview I shall present an overview of this assignment and discuss some of the specification details given below in class on Wednesday, September 17 & Monday, September 22. Client The client is evoked with a command line argument giving either the server IP address in dotted decimal notation, or the server domain name. The client has to be able to handle either mode and figure out which of the two is being passed to it. If it is given the IP address, it calls the gethostbyaddr function to get the domain name, which it then prints out to the user in the form of an appropriate message (e.g., ‘The server host is compserv1.cs.stonybrook.edu’). The function gethostbyname, on the other hand, returns the IP address that corresponds to a given domain name. The client then enters an infinite loop in which it queries the user which service is being requested. There are two options : echo and time (note that time is a slightly modified version of the daytime service – see below). The client then forks off a child. After the child is forked off, the parent process enters a second loop in which it continually reads and prints out status messages received from the child via a half-duplex pipe (see below). The parent exits the second loop when the child closes the pipe (how does the parent detect this?), and/or the SIGCHLD signal is generated when the child terminates. The parent then repeats the outer loop, querying the user again for the (next) service s/he desires. This cycle continues till the user responds to a query with quit rather than echo or time. The child process is the one which handles the actual service for the user. It execs (see Section 4.7, Chapter 4) an xterm to generate a separate window through which all interactions with server and user take place. For example, the following exec function call evokes an xterm, and gets the xterm to execute echocli, located in the current directory, passing the string 127.0.0.1 (assumed to be the IP address of the server) as the command line argument argv[1] to echocli (click on the url for further details) : execlp("xterm", "xterm", "-e", "./echocli", "127.0.0.1", (char *) 0) xterm executes one of two client programs (echocli or timecli, say) depending on the service requested. A client program establishes a TCP connection to the server at the ‘well-known port’ for the service (in reality, this port will, of course, be some ephemeral port of your choosing, the value of which is known to both server and client code). All interaction with the user, on the one hand, and with the server, on the other, takes place through the child’s xterm window, not the parent’s window. On the other hand, the child will use a half-duplex pipe to relay status information to the parent which the parent prints out in its window (see below).To terminate the echo client, the user can type in ^D (CTRL D, the EOF character). To terminate the time client, the only option is for the user to type in ^C (CTRL C). (This can also be used as an alternative means of terminating the echo client.) Note that using ^C in the context of the time service will give the server process the impression that the client process has ‘crashed’. It is your responsibility to ensure that the server process handles this correctly and closes cleanly. I shall address this further when discussing the server process. It is also part of your responsibility in this assignment to ensure that the client code is robust with respect to the server process crashing (see Sections 5.12 & 5.13, Chapter 5). Amongst other implications, this means that it would probably be a good idea for you to implement your echo client code along the lines of either : Figure 6.9, p.168 (or even Figure 6.13, p.174) which uses I/O multiplexing with the select function; or of Figure 26.2, p.680, which uses threads; rather than along the lines of Figure 5.5, p.125. When the child terminates, either normally or abnormally, its xterm window disappears instantaneously. Consequently, any status information that the child might want to communicate to the user should not be printed out on the child’s xterm window, since the user will not have time to see the final such message before the window disappears. Instead, as the parent forks off the child at the beginning, a half-duplex pipe should be established from child to parent. The child uses the pipe to send status reports to the parent, which the parent prints out in its window. I leave it up to you to decide what status information exactly should be relayed to the parent but, at a minimum, the parent should certainly be notified, in as precise terms as possible, of any abnormal termination conditions of the service provided by the child. In general, you should try to make your code as robust as possible with respect to handling errors, including confused behaviour by the user (e.g., passing an invalid command line argument; responding to a query incorrectly; trying to interact with the service through the parent process window, not the child process xterm; etc.). Amongst other things, you have to worry about EINTR errors occurring during slow system calls (such as the parent reading from the pipe, or, possibly, printing to stdout, for example) due to a SIGCHLD signal. What about other kinds of errors? Which ones can occur? How should you handle them? Server The server has to be able to handle multiple clients using threads (specifically, detached threads), not child processes (see Sections 26.1 to 26.4, Chapter 26). Furthermore, it has to be able to handle multiple types of service; in our case, two : echo and time. echo is just the standard echo service we have seen in class. time is a slightly modified version of the daytime service (see Figure 1.9, p.14) : instead of sending the client the ‘daytime’ just once and closing, the service sits in an infinite loop, sending the ‘daytime’, sleeping for 5 seconds, and repeating, ad infinitum. The server is loosely based on the way the inetd daemon works : see Figure 13.7, p.374. However, note that the differences between inetd and our server are probably more significant than the similarities: inetd forks off children, whereas our server uses threads; inetd child processes issue exec commands, which our server threads do not; etc. So you should treat Figure 13.7 (and Section 13.5, Chapter 13, generally) as a source of ideas, not as a set of specifications which you must slavishly adhere to and copy. Note, by the way, that there are some similarities between our client and inetd (primarily, forking off children which issue execs), which could be a useful source of ideas. The server creates a listening socket for each type of service that it handles, bound to the ‘well-known port’ for that service. It then uses select to await clients (Chapter 6; or, if you prefer, poll; note that pselect is not supported in Solaris 2.10). The socket on which a client connects identifies the service the client is seeking. The server accepts the connection and creates a thread which provides the service. The thread detaches itself. Meanwhile, the main thread goes back to the select to await further clients. A major concern when using threads is to make sure that operations are thread safe (see p.685 and on into Section 26.5). In this respect, Stevens’ readline function (in Stevens’ file unpv13e/lib/readline.c, see Figure 3.18, pp.91-92) poses a particular problem. On p.686, the authors give three options for dealing with this. The third option is too inefficient and should be discarded. You can implement the second option if you wish. Easiest of all would be the first option, since it involves using a thread-safe version of readline (see Figures 26.11 & 26.12) provided in file unpv13e/threads/readline.c. Whatever you do, remember that Stevens’ library, libunp.a, contains the non-thread-safe version of Figure 3.18, and that is the version that will be link-loaded to your code unless you undertake explicit steps to ensure this does not happen (libunp.a also contains the ‘wrapper’ function Readline, whose code is also in file unpv13e/lib/readline.c). Remaking your copy of libunp.a with the ‘correct’ version of readline is not a viable option because when you hand in your code, it will be compiled and link-loaded with respect to the version of libunp.a in the course account, ~cse533/Stevens/unpv13e_solaris2.10 (I do not intend to change that version since it risks creating confusion later on in the course). Also, you will probably want to use the original version of readline in the client code anyway. I am providing you with a sample Makefile which picks up the thread-safe version of readline from directory ~cse533/Stevens/unpv13e_solaris2.10/threads and uses it when making the executable for the server, but leaves the other executables it makes to link-load the non-thread-safe version from libunp.a. Again, it is part of your responsibility to make sure that your server code is as robust as possible with respect to errors, and that the server threads terminate cleanly under all circumstances. Recall, first of all, that the client user will often use ^C (CTRL C) in the xterm to terminate the service. This will appear to the server thread as if the client process has crashed. You need to think about the error conditions that will be induced (see Sections 5.11 to 5.13, Chapter 5), and how the echo and time server code is to detect and handle these conditions. For example, the time server will almost certainly experience an EPIPE error (see Section 5.13). How should the associated SIGPIPE signal be handled? Be aware that when we return out of the Stevens’ writen function with -1 (indicating an error) and check errno, errno is sometimes equal to 0, not EPIPE (value 32). This can happen under Solaris 2.10, but I am not sure under precisely what conditions nor why. Nor am I sure if it also happens under other Unix versions, or if it also happens when using write rather than writen. The point is, you cannot depend on errno to find out what has happened to the write or writen functions. My suggestion, therefore, is that the time server should use the select function. On the one hand, select’s timeout mechanism can be used to make the server sleep for the 5 seconds. On the other hand, select should also monitor the connection socket read event because, when the client xterm is ^C’ed, a FIN will be sent to the server TCP, which will prime the socket for reading; a read on the socket will then return with value 0 (see Figure 14.3, p. 385 as an example). But what about errors other than EPIPE? Which ones can occur? How should you handle them? Recall, as well, that if a thread terminates without explicitly closing the connection socket it has been using, the connection socket will remain existent until the server process itself dies (why?). Since the server process is supposed, in principle, to run for ever, you risk ending up with an ever increasing number of unused, ‘orphaned’ sockets unless you are careful. Whenever a server thread detects the termination of its client, it should print out a message giving appropriate details: e.g., “Client termination: EPIPE error detected”, “Client termination: socket read returned with value 0”, “Client termination: socket read returned with value -1, errno = . . .”, and so on. When debugging your server code, you will probably find that restarting the server very shortly after it was last running will give you trouble when it comes to bind to its ‘well-known ports’. This is because, when the server side initiates connection termination (which is what will happen if the server process crashes; or if you kill it first, before killing the client) TCP keeps the connections open in the TIME_WAIT state for 2MSLs (Sections 2.6 & 2.7, Chapter 2). This could very quickly become a major irritant. I suggest you explore the possibility of using the SO_REUSEADDR socket option (pp.210-213, Chapter 7; note that the SO_REUSEPORT socket option is not supported in Solaris 2.10), which should help keep the stress level down. You will need to use the setsockopt function (Section 7.2) to enable this option. Figure 8.24, p.263, shows an instance of server code that sets the SO_REUSEADDR socket option. Finally, you should be aware of the sort of problem, described in Section 16.6, pp.461-463, that might occur when (blocking) listening sockets are monitored using select. Such sockets should be made nonblocking, which requires use of the fcntl function after socket creates the socket, but before listen turns the socket into a listening socket.

Overview For this assignment you will be developing an application that uses raw IP sockets to ‘walk’ around an ordered list of nodes (given as a command line argument at the ‘source’ node, which is the node at which the tour was initiated), in a manner similar to the IP SSRR (Strict Source and Record Route) option. At each node, the application pings the preceding node in the tour. However, unlike the ping code in Stevens, you will be sending the ping ICMP echo request messages through a SOCK_RAW-type PF_PACKET socket and implementing ARP functionality to find the Ethernet address of the target node. Finally, when the ‘walk’ is completed, the group of nodes visited on the tour will exchange multicast messages. Your code will consist of two process modules, a ‘Tour’ application module (which will implement all the functionality outlined above, except for ARP activity) and an ARP module. The following should prove to be useful reference material for the assignment: Sections 21.2, 21.3, 21.6 and 21.10, Chapter 21, on Multicasting. Sections 27.1 to 27.3, Chapter 27, on the IP SSRR option. Sections 28.1 to 28.5, Chapter 28, on raw sockets, the IP_HDRINCL socket option, and ping. Sections 15.5, Chapter 15, on Unix domain SOCK_STREAM sockets. Figure 29.14, p. 807, and the corresponding explanation on p. 806, on filling in an IP header when the IP_HDRINCL socket option is in effect. The Lecture Slides on ARP & RARP (especially Section 4.4, ARP Packet Format, and the Figure 4.3 it includes). The link http://www.pdbuchan.com/rawsock/rawsock.html contains useful code samples that use IP raw sockets and PF_PACKET sockets. Note, in partcular, the code “icmp4_ll.c” in Table 2 for building an echo request sent through a PF_PACKET SOCK_RAW socket. The VMware environment You will be using the same vm1 , . . . . . , vm10 nodes you used for Assignment 3. However, unlike Assignment 3, you should use only interfaces eth0 and their associated IP addresses and ignore the other Ethernet interfaces that nodes have (interfaces eth0 make vm1 , . . . . . , vm10 look as if they belong to the same Ethernet LAN segment IP network 130.245.156.0/24). Note that, apart from the primary IP addresses associated with interfaces eth0, some nodes might also have one or more alias IP addresses associated with their interface eth0. Tour application module specifications The application will create a total of four sockets: two IP raw sockets, a PF_PACKET socket and a UDP socket for multicasting. We shall call the two IP raw sockets the ‘rt ’ (‘route traversal’) and ‘pg ’ (‘ping’) sockets, respectively. The rt socket should have the IP_HDRINCL option set. You will only be receiving ICMP echo reply messages through the pg socket (and not sending echo requests), so it does not matter whether it has the IP_HDRINCL option set or not. The pg socket should have protocol value (i.e., protocol demultiplexing key in the IP header) IPPROTO_ICMP. The rt socket should have a protocol value that identifies the application - i.e., some value other than the IPPROTO_XXXX values in /usr/include/netinet/in.h. However, remember that you will all be running your code using the same root account on the vm1 , . . . . . , vm10 nodes. So if two of you happen to choose the same protocol value and happen to be running on the same vm node at the same time, your applications will receive each other’s IP packets. For that reason, try to choose a protocol value for your rt socket that is likely to be unique to yourself. The PF_PACKET socket should be of type SOCK_RAW (not SOCK_DGRAM). This socket should have a protocol value of ETH_P_IP = 0x0800 (IPv4). The UDP socket for multicasting will be discussed below. Note that, depending on how you choose to bind that socket, you might actually need to have two UDP sockets for multicast communication – see bottom of p. 576, Section 21.10. Your application will, of course, have to be running on every vm node that is included in the tour. When evoking the application on the source node, the user supplies a sequence of vm node names (not IP addresses) to be visited in order. This command line sequence starts with the next node to be visited from the source node (i.e., it does not start with the source node itself). The sequence can include any number of repeated visits to the same node. For example, suppose that the source node is vm3 and the executable is called badr_tour : [root@vm3/root]# badr_tour vm2 vm10 vm4 vm7 vm5 vm2 vm6 vm2 vm9 vm4 vm7 vm2 vm6 vm5 vm1 vm10 vm8 (but note that the tour does not necessarily have to visit every vm node; and the same node should not appear consequentively in the tour list – i.e., the next node on the tour cannot be the current node itself). The application turns the sequence into a list of IP addresses for source routing. It also adds the IP address of the source node itself to the beginning of the list. The list thus produced will be carried as the payload of an IP packet, not as a SSRR option in the packet header. It is our application which will ensure that every node in the sequence is visited in order, not the IP SSRR capability. The source node should also add to the list an IP multicast address and a port number of its choice. It should also join the multicast group at that address and port number on its UDP socket. The TTL for outgoing multicasts should be set to 1. The application then fills in the header of an IP packet, designating itself as the IP source, and the next node to be visited as the IP destination. The packet is sent out on the rt socket. Note that on Linux, all the fields of the packet header must be in network byte order (Stevens, Section 28.3, p. 737, the fourth bullet point). When filling in the packet header, you should explicitly fill in the identification field (recall that, with the IP_HDRINCL socket option, if the identification field is given value 0, then the kernel will set its value). Try to make sure that the value you choose is likely to be unique to yourself (for reasons similar to those explained with respect to the IPPROTO_XXXX in 1. above). When a node receives an IP packet on its rt socket, it should first check that the identification field carries the right value (this implies that you will hard code your choice of identification field value determined in item 2 above in your code). If the identification field value does not check out, the packet is ignored. For a valid packet : Print out a message along the lines of: <time> received source routing packet from <hostname> <time> is the current time in human-readable format (see lines 19 & 20 in Figure 1.9, p. 14, and the corresponding explanation on p. 14f.), and <hostname> is the host name corresponding to the source IP address in the header of the received packet. If this is the first time the node is visited, the application should use the multicast address and port number in the packet received to join the multicast group on its UDP socket. The TTL for outgoing multicasts should be set to 1. The application updates the list in the payload, so that the next node in the tour can easily identify what the next hop from itself will be when it receives the packet. How you do this I leave up to you. You could, for example, include as part of the payload a pointer field into the list of nodes to be visited. This pointer would then be updated to the next entry in the list as the packet progresses hop by hop (see Figure 27.1 and the associated explanation on pp. 711-712). Other solutions are, of course, possible. The application then fills in a new IP header, designating itself as the IP source, and the next node to be visited as the IP destination. The identification field should be set to the same value as in the received packet. The packet is sent out on the rt socket. The node should also initiate pinging to the preceding node in the tour (the IP address of which it should pick up from the header of the received packet). However, unlike the Stevens ping code, it will be using the SOCK_RAW-type PF_PACKET socket of item 1 above to send the ICMP echo request messages. Before it can send echo request messages, the application has to call on the ARP module you will implement to get the Ethernet address of this preceding / ‘target’ node; this call is made using the API function areq which you will also implement (see sections ARP module specifications & API specifications below). Note that ARP has to be evoked every time the application wants to send out an echo request message, and not just the first time. An echo request message has to be encapsulated in a properly-formulated IP packet, which is in turn encapsulated in a properly-formulated Ethernet frame transmitted out through the PF_PACKET socket ; otherwise, ICMP at the source node will not receive it. You will have to modify Stevens’ ping code accordingly, specifically, the send_v4 function. In particular, the Ethernet frame must have a value of ETH_P_IP = 0x0800 (IPv4 – see <linux/if_ether.h>) in the frame type / ‘length’ field ; and the encapsulated IP packet must have a value of IPPROTO_ICMP = 0x01 (ICMPv4 – see <netinet_in.h>) in its protocol field. You should also simplify the ping code in its entirety by stripping all the ‘indirection’ IPv4 / IPv6 dual-operability paraphernalia and making the code work just for IPv4. Also note that the functions host_serv and freeaddrinfo, together with the associated structure addrinfo (see Sections 11.6, 11.8 & 11.11), in Figures 27.3, 27.6 & 28.5 ( pp. 713, 716 & 744f., respectively) can be replaced by the function gethostbyname and associated structure hostent (see Section 11.3) where needed. Also, there is no ‘-v’ verbose option, so this too should be stripped from Stevens’ code. When a node is ready to start pinging, it first prints out a ‘PING’ message similar to lines 32-33 of Figure 28.5, p. 744. It then builds up ICMP echo request messages and sends them to the source node every 1 second through the PF_PACKET socket. It also reads incoming echo response messages off the pg socket, in response to which it prints out the same kind of output as the code of Figure 28.8, p. 748. If this node and its preceding node have been previously visited in that order during the tour, then pinging would have already been initiated from the one to the other in response to the first visit, and nothing further should nor need be done during second and subsequent visits. In light of the above, note that once a node initiates pinging, it needs to read from both its rt and pg sockets, necessitating the use of the select function. As will be clear from what follows below, the application will anyway be needing also to simultaneously monitor its UDP socket for incoming multicast datagrams. When the last node on the tour is reached, and if this is the first time it is visited, it joins the multicast group and starts pinging the preceding node (if it is not already doing so). After a few echo replies are received (five, say), it sends out the multicast message below on its UDP socket (i.e., the node should wait about five seconds before sending the multicast message) : <<<<< This is node vmi . Tour has ended . Group members please identify yourselves. >>>>> where vmi is the name (not IP address) of the node. The node should also print this message out on stdout preceded, on the same line, by the phrase: Node vmi . Sending: <then print out the message sent>. Each node vmj receiving this message should print out the message received preceded, on the same line, by the phrase: Node vmj . Received <then print out the message received>. Each such node in step a above should then immediately stop its pinging activity. The node should then send out the following multicast message: <<<<< Node vmj . I am a member of the group. >>>>> and print out this message preceded, on the same line, by the phrase: Node vmj . Sending: <then print out the message sent>. Each node receiving these second multicast messages (i.e., the messages that nodes – including itself – sent out in step c above) should print each such message out preceded, on the same line, by the phrase: Node vmk . Received: <then print out the message received>. Reading from the socket in step d above should be implemented with a 5-second timeout. When the timeout expires, the node should print out another message to the effect that it is terminating the Tour application, and gracefully exit its Tour process. Note that under Multicast specifications, the last node in the tour, which sends out the End of Tour message, should itself receive a copy of that message and, when it does, it should behave exactly as do the other nodes in steps a. – e. above. ARP module specifications Your executable is evoked with no command line arguments. Like the Tour module, it will be running on every vm node. It uses the get_hw_addrs function of Assignment 3 to explore its node’s interfaces and build a set of <IP address , HW address> matching pairs for all eth0 interface IP addresses (including alias IP addresses, if any). Write out to stdout in some appropriately clear format the address pairs found. The module creates two sockets: a PF_PACKET socket and a Unix domain socket. The PF_PACKET should be of type SOCK_RAW (not type SOCK_DGRAM) with a protocol value of your choice (but not one of the standard values defined in <linux/if_ether.h>) which is, hopefully, unique to yourself. This value effectively becomes the protocol value for your implementation of ARP. Because this protocol value will be carried in the frame type / ‘length’ field of the Ethernet frame header (see Figure 4.3 of the ARP & RARP handout), the value chosen should be not less than 1536 (0x600) so that it is not misinterpreted as the length of an Ethernet 802.3 frame. The Unix domain socket should be of type SOCK_STREAM (not SOCK_DGRAM). It is a listening socket bound to a ‘well-known’ sun_path file. This socket will be used to communicate with the function areq that is implemented in the Tour module (see the section API specifications below). In this context, areq will act as the client and the ARP module as the server. The ARP module then sits in an infinite loop, monitoring these two sockets. As ARP request messages arrive on the PF_PACKET socket, the module processes them, and responds with ARP reply messages as appropriate. The protocol builds a ‘cache’ of matching <IP address , HW address> pairs from the replies (and requests – see below) it receives. For simplicity, and unlike the real ARP, we shall not implement timing out mechanisms for these cache entries. A cache entry has five parts: (i) IP address ; (ii) HW address ; (iii) sll_ifindex (the interface to be used for reaching the matching pair <(i) , (ii)>) ; (iv) sll_hatype ; and (v) a Unix-domain connection-socket descriptor for a connected client (see the section API specifications below for the latter three). When an ARP reply is being entered in the cache, the ARP module uses the socket descriptor in (v) to send a reply to the client, closes the connection socket, and deletes the socket descriptor from the cache entry. Note that, like the real ARP, when an ARP request is received by a node, and if the request pertains to that receiving node, the sender’s (see Figure 4.3 of the ARP & RARP handout) <IP address, HW address> matching pair should be entered into the cache if it is not already there (together, of course, with (iii) sll_ifindex & (iv) sll_hatype), or updated if need be if such an entry already exists in the cache. If the ARP request received does not pertain to the node receiving it, but there is already an entry in that receiving node's cache for the sender’s <IP address, HW address> matching pair, that entry should be checked and updated if need be. If there is no such entry, no action is taken (in particular, and unlike the case above, no new entry should be made in the receiving node's cache of the sender’s <IP address, HW address> matching pair if such an entry does not already exist). ARP request and reply messages have the same format as Figure 4.3 of the ARP & RARP handout, but with an extra 2-byte identification field added at the beginning which you fill with a value chosen so that it has a high probability of being unique to yourself. This value is to be echoed in the reply message, and helps to act as a further filter in case some other student happens to have fortuitously chosen the same value as yourself for the protocol parameter of the ARP PF_PACKET. Values in the fields of our ARP messages must be in network byte order. You might find the system header file <linux/if_arp.h> useful for manipulating ARP request and reply messages, but remember that our version of these messages have an extra two-byte field as mentioned above. Your code should print out on stdout, in some appropriately clear format, the contents of the Ethernet frame header and ARP request message you send. As described in Section 4.4 of the ARP & RARP handout, the node that responds to the request should, in its reply message, swap the two sender addresses with the two target addresses, as well as, of course, echo back the extra identification field sent with the request. The protocol at this responding node should print out, in an appropriately clear format, both the request frame (header and ARP message) it receives and the reply frame it sends. Similarly, the node that sent the request should print out the reply frame it receives. Finally, recall that the node issuing the request sends out a broadcast Ethernet frame, but the responding node replies with a unicast frame. API specifications The API is for communication between the Tour process and the ARP process. It consists of a single function, areq, implemented in the Tour module. areq is called by send_v4 function of the application every time the latter want to send out an ICMP echo request message: int areq (struct sockaddr *IPaddr, socklen_t sockaddrlen, struct hwaddr *HWaddr); IPaddr contains the primary or alias IPaddress of a ‘target’ node on the LAN for which the corresponding hardware address is being requested. hwaddr is a new structure (and not a pre-existing type) modeled on the sockaddr_ll of PF_PACKET; you will have to declare it in your code. It is used to return the requested hardware address to the caller of areq : structure hwaddr { int sll_ifindex; /* Interface number */ unsigned short sll_hatype; /* Hardware type */ unsigned char sll_halen; /* Length of address */ unsigned char sll_addr[8]; /* Physical layer address */ }; areq creates a Unix domain socket of type SOCK_STREAM and connects to the ‘well-known’ sun_path file of the ARP listening socket. It sends the IP address from parameter IPaddr and the information in the three fields of parameter HWaddr to ARP. It then blocks on a read awaiting a reply from ARP. This read should be backed up by a timeout since it is possible that no reply is received for the request. If a timeout occurs, areq should close the socket and return to its caller indicating failure (through its int return value). Your application code should print out on stdout, in some appropriately clear format, a notification every time areq is called, giving the IP address for which a HW address is being sought. It should similarly print out the result when the call to areq returns (HW address returned, or failure). When the ARP module receives a request for a HW address from areq through its Unix domain listening socket, it first checks if the required HW address is already in the cache. If so, it can respond immediately to the areq and close the Unix domain connection socket. Else : it makes an ‘incomplete’ entry in the cache, consisting of parts (i), (iii), (iv) and (v) ; puts out an ARP request message on the network on its PF_PACKET socket; and starts monitoring the areq connection socket for readability – if the areq client closes the connection socket (this would occur in response to a timeout in areq), ARP deletes the corresponding incomplete entry from the cache (and ignores any subsequent ARP reply from the network if such is received). On the other hand, if ARP receives a reply from the network, it updates the incomplete cache entry, responds to areq, and closes the connection socket.

In this notebook, we'll be building a generative adversarial network (GAN) trained on the MNIST dataset. From this, we'll be able to generate new handwritten digits! GANs were first reported on in 2014 from Ian Goodfellow and others in Yoshua Bengio's lab. Since then, GANs have exploded in popularity. Here are a few examples to check out: Pix2Pix CycleGAN & Pix2Pix in PyTorch, Jun-Yan Zhu A list of generative models The idea behind GANs is that you have two networks, a generator 𝐺 and a discriminator 𝐷 , competing against each other. The generator makes "fake" data to pass to the discriminator. The discriminator also sees real training data and predicts if the data it's received is real or fake. The generator is trained to fool the discriminator, it wants to output data that looks as close as possible to real, training data. The discriminator is a classifier that is trained to figure out which data is real and which is fake. What ends up happening is that the generator learns to make data that is indistinguishable from real data to the discriminator. The general structure of a GAN is shown in the diagram above, using MNIST images as data. The latent sample is a random vector that the generator uses to construct its fake images. This is often called a latent vector and that vector space is called latent space. As the generator trains, it figures out how to map latent vectors to recognizable images that can fool the discriminator. If you're interested in generating only new images, you can throw out the discriminator after training. In this notebook, I'll show you how to define and train these adversarial networks in PyTorch and generate new images!

Overview For this assignment you will be developing and implementing : An On-Demand shortest-hop Routing (ODR) protocol for networks of fixed but arbitrary and unknown connectivity, using PF_PACKET sockets. The implementation is based on (a simplified version of) the AODV algorithm. Time client and server applications that send requests and replies to each other across the network using ODR. An API you will implement using Unix domain datagram sockets enables applications to communicate with the ODR mechanism running locally at their nodes. I shall be discussing the assignment in class on Wednesday, October 29, and Monday, November 3. The following should prove useful reference material for the assignment : Sections 15.1, 15.2, 15.4 & 15.6, Chapter 15, on Unix domain datagram sockets. PF_PACKET(7) from the Linux manual pages. You might find these notes made by a past CSE 533 student useful. Also, the following link http://www.pdbuchan.com/rawsock/rawsock.html contains useful code samples that use PF_PACKET sockets (as well as other code samples that use raw IP sockets which you do not need for this assignment, though you will be using these types of sockets for Assignment 4). Charles E. Perkins & Elizabeth M. Royer. “Ad-hoc On-Demand Distance Vector Routing.” Proceedings of the 2nd IEEE Workshop on Mobile Computing Systems and Applications, New Orleans, Louisiana, February 1999, pp. 90 - 100. The VMware environment minix.cs.stonybrook.edu is a Linux box running VMware. A cluster of ten Linux virtual machines, called vm1 through vm10, on which you can gain access as root and run your code have been created on minix. See VMware Environment Hosts for further details. VMware instructions takes you to a page that explains how to use the system. The ten virtual machines have been configured into a small virtual intranet of Ethernet LANs whose topology is (in principle) unknown to you. There is a course account cse533 on node minix, with home directory /users/cse533. In there, you will find a subdirectory Stevens/unpv13e , exactly as you are used to having on the cs system. You should develop your source code and makefiles for handing in accordingly. You will be handing in your source code on the minix node. Note that you do not need to link against the socket library (-lsocket) in Linux. The same is true for -lnsl and -lresolv. For example, take a look at how the LIBS variable is defined for Solaris, in /home/courses/cse533/Stevens/unpv13e_solaris2.10/Make.defines (on compserv1, say) : LIBS = ../libunp.a -lresolv -lsocket -lnsl -lpthread But if you take a look at Make.defines on minix (/users/cse533/Stevens/unpv13e/Make.defines) you will find only: LIBS = ../libunp.a -lpthread The nodes vm1 , . . . . . , vm10 are all multihomed : each has two (or more) interfaces. The interface ‘eth0 ’ should be completely ignored and is not to be used for this assignment (because it shows all ten nodes as if belonging to the same single Ethernet 192.168.1.0/24, rather than to an intranet composed of several Ethernets). Note that vm1 , . . . . . , vm10 are virtual machines, not real ones. One implication of this is that you will not be able to find out what their (virtual) IP addresses are by using nslookup and such. To find out these IP addresses, you need to look at the file /etc/hosts on minix. More to the point, invoking gethostbyname for a given vm will return to you only the (primary) IP address associated with the interface eth0 of that vm (which is the interface you will not be using). It will not return to you any other IP address for the node. Similarly, gethostbyaddr will return the vm node name only if you give it the (primary) IP address associated with the interface eth0 for the node. It will return nothing if you give it any other IP address for the node, even though the address is perfectly valid. Because of this, and because it will ease your task to be able to use gethostbyname and gethostbyaddr in a straightforward way, we shall adopt the (primary) IP addresses associated with interfaces eth0 as the ‘canonical’ IP addresses for the nodes (more on this below). Time client and server A time server runs on each of the ten vm machines. The client code should also be available on each vm so that it can be evoked at any of them. Normally, time clients/servers exchange request/reply messages using the TCP/UDP socket API that, effectively, enables them to receive service (indirectly, via the transport layer) from the local IP mechanism running at their nodes. You are to implement an API using Unix domain sockets to access the local ODR service directly (somewhat similar, in effect, to the way that raw sockets permit an application to access IP directly). Use Unix domain SOCK_DGRAM, rather than SOCK_STREAM, sockets (see Figures 15.5 & 15.6, pp. 418 - 419). API You need to implement a msg_send function that will be called by clients/servers to send requests/replies. The parameters of the function consist of : int giving the socket descriptor for write char* giving the ‘canonical’ IP address for the destination node, in presentation format int giving the destination ‘port’ number char* giving message to be sent int flag if set, force a route rediscovery to the destination node even if a non-‘stale’ route already exists (see below) msg_send will format these parameters into a single char sequence which is written to the Unix domain socket that a client/server process creates. The sequence will be read by the local ODR from a Unix domain socket that the ODR process creates for itself. Recall that the ‘canonical’ IP address for a vm node is the (primary) IP address associated with the eth0 interface for the node. It is what will be returned to you by a call to gethostbyname. Similarly, we need a msg_recv function which will do a (blocking) read on the application domain socket and return with : int giving socket descriptor for read char* giving message received char* giving ‘canonical’ IP address for the source node of message, in presentation format int* giving source ‘port’ number This information is written as a single char sequence by the ODR process to the domain socket that it creates for itself. It is read by msg_recv from the domain socket the client/server process creates, decomposed into the three components above, and returned to the caller of msg_recv. Also see the section below entitled ODR and the API. Client When a client is evoked at a node, it creates a domain datagram socket. The client should bind its socket to a ‘temporary’ (i.e., not ‘well-known’) sun_path name obtained from a call to tmpnam() (cf. line 10, Figure 15.6, p. 419) so that multiple clients may run at the same node. Note that tmpnam() is actually highly deprecated. You should use the mkstemp() function instead - look up the online man pages on minix (‘man mkstemp’) for details. As you run client code again and again during the development stage, the temporary files created by the calls to tmpnam / mkstemp start to proliferate since these files are not automatically removed when the client code terminates. You need to explicitly remove the file created by the client evocation by issuing a call to unlink() or to remove() in your client code just before the client code exits. See the online man pages on minix (‘man unlink’, ‘man remove’) for details. The client then enters an infinite loop repeating the steps below. The client prompts the user to choose one of vm1 , . . . . . , vm10 as a server node. Client msg_sends a 1 or 2 byte message to server and prints out on stdout the message client at node vm i1 sending request to server at vm i2 (In general, throughout this assignment, “trace” messages such as the one above should give the vm names and not IP addresses of the nodes.) Client then blocks in msg_recv awaiting response. This attempt to read from the domain socket should be backed up by a timeout in case no response ever comes. I leave it up to you whether you ‘wrap’ the call to msg_recv in a timeout, or you implement the timeout inside msg_recv itself. When the client receives a response it prints out on stdout the message client at node vm i1 : received from vm i2 <timestamp> If, on the other hand, the client times out, it should print out the message client at node vm i1 : timeout on response from vm i2 The client then retransmits the message out, setting the flag parameter in msg_send to force a route rediscovery, and prints out an appropriate message on stdout. This is done only once, when a timeout for a given message to the server occurs for the first time. Client repeats steps 1. - 3. Server The server creates a domain datagram socket. The server socket is assumed to have a (node-local) ‘well-known’ sun_path name which it binds to. This ‘well-known’ sun_path name is designated by a (network-wide) ‘well-known’ ‘port’ value. The time client uses this ‘port’ value to communicate with the server. The server enters an infinite sequence of calls to msg_recv followed by msg_send, awaiting client requests and responding to them. When it responds to a client request, it prints out on stdout the message server at node vm i1 responding to request from vm i2 ODR The ODR process runs on each of the ten vm machines. It is evoked with a single command line argument which gives a “staleness” time parameter, in seconds. It uses get_hw_addrs (available to you on minix in ~cse533/Asgn3_code) to obtain the index, and associated (unicast) IP and Ethernet addresses for each of the node’s interfaces, except for the eth0 and lo (loopback) interfaces, which should be ignored. In the subdirectory ~cse533/Asgn3_code (/users/cse533/Asgn3_code) on minix I am providing you with two functions, get_hw_addrs and prhwaddrs. These are analogous to the get_ifi_info_plus and prifinfo_plus of Assignment 2. Like get_ifi_info_plus, get_hw_addrs uses ioctl. get_hw_addrs gets the (primary) IP address, alias IP addresses (if any), HW address, and interface name and index value for each of the node's interfaces (including the loopback interface lo). prhwaddrs prints that information out. You should modify and use these functions as needed. Note that if an interface has no HW address associated with it (this is, typically, the case for the loopback interface lo for example), then ioctl returns get_hw_addrs a HW address which is the equivalent of 00:00:00:00:00:00 . get_hw_addrs stores this in the appropriate field of its data structures as it would with any HW address returned by ioctl, but when prhwaddrs comes across such an address, it prints a blank line instead of its usual ‘HWaddr = xx:xx:xx:xx:xx:xx’. The ODR process creates one or more PF_PACKET sockets. You will need to try out PF_PACKET sockets for yourselves and familiarize yourselves with how they behave. If, when you read from the socket and provide a sockaddr_ll structure, the kernel returns to you the index of the interface on which the incoming frame was received, then one socket will be enough. Otherwise, somewhat in the manner of Assignment 2, you shall have to create a PF_PACKET socket for every interface of interest (which are all the interfaces of the node, excluding interfaces lo and eth0 ), and bind a socket to each interface. Furthermore, if the kernel also returns to you the source Ethernet address of the frame in the sockaddr_ll structure, then you can make do with SOCK_DGRAM type PF_PACKET sockets; otherwise you shall have to use SOCK_RAW type sockets (although I would prefer you to use SOCK_RAW type sockets anyway, even if it turns out you can make do with SOCK_DGRAM type). The socket(s) should have a protocol value (no larger than 0xffff so that it fits in two bytes; this value is given as a network-byte-order parameter in the call(s) to function socket) that identifies your ODR protocol. The <linux/if_ether.h> include file (i.e., the file /usr/include/linux/if_ether.h) contains protocol values defined for the standard protocols typically found on an Ethernet LAN, as well as other values such as ETH_P_ALL. You should set protocol to a value of your choice which is not a <linux/if_ether.h> value, but which is, hopefully, unique to yourself. Remember that you will all be running your code using the same root account on the vm1 , . . . . . , vm10 nodes. So if two of you happen to choose the same protocol value and happen to be running on the same vm node at the same time, your applications will receive each other’s frames. For that reason, try to choose a protocol value for the socket(s) that is likely to be unique to yourself (something based on your Stony Brook student ID number, for example). This value effectively becomes the protocol value for your implementation of ODR, as opposed to some other cse 533 student's implementation. Because your value of protocol is to be carried in the frame type field of the Ethernet frame header, the value chosen should be not less than 1536 (0x600) so that it is not misinterpreted as the length of an Ethernet 802.3 frame. Note from the man pages for packet(7) that frames are passed to and from the socket without any processing in the frame content by the device driver on the other side of the socket, except for calculating and tagging on the 4-byte CRC trailer for outgoing frames, and stripping that trailer before delivering incoming frames to the socket. Nevertheless, if you write a frame that is less than 60 bytes, the necessary padding is automatically added by the device driver so that the frame that is actually transmitted out is the minimum Ethernet size of 64 bytes. When reading from the socket, however, any such padding that was introduced into a short frame at the sending node to bring it up to the minimum frame size is not stripped off - it is included in what you receive from the socket (thus, the minimum number of bytes you receive should never be less than 60). Also, you will have to build the frame header for outgoing frames yourselves (assuming you use SOCK_RAW type sockets). Bear in mind that the field values in that header have to be in network order. The ODR process also creates a domain datagram socket for communication with application processes at the node, and binds the socket to a ‘well known’ sun_path name for the ODR service. Because it is dealing with fixed topologies, ODR is, by and large, considerably simpler than AODV. In particular, discovered routes are relatively stable and there is no need for all the paraphernalia that goes with the possibility of routes changing (such as maintenance of active nodes in the routing tables and timeout mechanisms; timeouts on reverse links; lifetime field in the RREP messages; etc.) Nor will we be implementing source_sequence_#s (in the RREQ messages), and dest_sequence_# (in RREQ and RREP messages). In reality, we should (though we will not, for the sake of simplicity, be doing so) implement some sort of sequence number mechanism, or some alternative mechanism such as split-horizon for example, if we are to avoid possible scenarios of routing loops in a “count to infinity” context (I shall explain this point in class). However, we want ODR to discover shortest-hop paths, and we want it to do so in a reasonably efficient manner. This necessitates having one or two aspects of its operations work in a different, possibly slightly more complicated, way than AODV does. ODR has several basic responsibilities : Build and maintain a routing table. For each destination in the table, the routing table structure should include, at a minimum, the next-hop node (in the form of the Ethernet address for that node) and outgoing interface index, the number of hops to the destination, and a timestamp of when the the routing table entry was made or last “reconfirmed” / updated. Note that a destination node in the table is to be identified only by its ‘canonical’ IP address, and not by any other IP addresses the node has. Generate a RREQ in response to a time client calling msg_send for a destination for which ODR has no route (or for which a route exists, but msg_send has the flag parameter set or the route has gone ‘stale’ – see below), and ‘flood’ the RREQ out on all the node’s interfaces (except for the interface it came in on and, of course, the interfaces eth0 and lo). Flooding is done using an Ethernet broadcast destination address (0xff:ff:ff:ff:ff:ff) in the outgoing frame header. Note that a copy of the broadcast packet is supposed to / might be looped back to the node that sends it (see p. 535 in the Stevens textbook). ODR will have to take care not to treat these copies as new incoming RREQs. Also note that ODR at the client node increments the broadcast_id every time it issues a new RREQ for any destination node. When a RREQ is received, ODR has to generate a RREP if it is at the destination node, or if it is at an intermediate node that happens to have a route (which is not ‘stale’ – see below) to the destination. Otherwise, it must propagate the RREQ by flooding it out on all the node’s interfaces (except the interface the RREQ arrived on). Note that as it processes received RREQs, ODR should enter the ‘reverse’ route back to the source node into its routing table, or update an existing entry back to the source node if the RREQ received shows a shorter-hop route, or a route with the same number of hops but going through a different neighbour. The timestamp associated with the table entry should be updated whenever an existing route is either “reconfirmed” or updated. Obviously, if the node is going to generate a RREP, updating an existing entry back to the source node with a more efficient route, or a same-hops route using a different neighbour, should be done before the RREP is generated. Unlike AODV, when an intermediate node receives a RREQ for which it generates a RREP, it should nevertheless continue to flood the RREQ it received if the RREQ pertains to a source node whose existence it has heretofore been unaware of, or the RREQ gives it a more efficient route than it knew of back to the source node (the reason for continuing to flood the RREQ is so that other nodes in the intranet also become aware of the existence of the source node or of the potentially more optimal reverse route to it, and update their tables accordingly). However, since an RREP for this RREQ is being sent by our node, we do not want other nodes who receive the RREQ propagated by our node, and who might be in a position to do so, to also send RREPs. So we need to introduce a field in the RREQ message, not present in the AODV specifications, which acts like a “RREP already sent” field. Our node sets this field before further propagating the RREQ and nodes receiving an RREQ with this field set do not send RREPs in response, even if they are in a position to do so. ODR may, of course, receive multiple, distinct instances of the same RREQ (the combination of source_addr and broadcast_id uniquely identifies the RREQ). Such RREQs should not be flooded out unless they have a lower hop count than instances of that RREQ that had previously been received. By the same token, if ODR is in a position to send out a RREP, and has already done so for this, now repeating, RREQ , it should not send out another RREP unless the RREQ shows a more efficient, previously unknown, reverse route back to the source node. In other words, ODR should not generate essentially duplicative RREPs, nor generate RREPs to instances of RREQs that reflect reverse routes to the source that are not more efficient than what we already have. Relay RREPs received back to the source node (this is done using the ‘reverse’ route entered into the routing table when the corresponding RREQ was processed). At the same time, a ‘forward’ path to the destination is entered into the routing table. ODR could receive multiple, distinct RREPs for the same RREQ. The ‘forward’ route entered in the routing table should be updated to reflect the shortest-hop route to the destination, and RREPs reflecting suboptimal routes should not be relayed back to the source. In general, maintaining a route and its associated timestamp in the table in response to RREPs received is done in the same manner described above for RREQs. Forward time client/server messages along the next hop. (The following is important – you will lose points if you do not implement it.) Note that such application payload messages (especially if they are the initial request from the client to the server, rather than the server response back to the client) can be like “free” RREPs, enabling nodes along the path from source (client) to destination (server) node to build a reverse path back to the client node whose existence they were heretofore unaware of (or, possibly, to update an existing route with a more optimal one). Before it forwards an application payload message along the next hop, ODR at an intermediate node (and also at the final destination node) should use the message to update its routing table in this way. Thus, calls to msg_send by time servers should never cause ODR at the server node to initiate RREQs, since the receipt of a time client request implies that a route back to the client node should now exist in the routing table. The only exception to this is if the server node has a staleness parameter of zero (see below). A routing table entry has associated with it a timestamp that gives the time the entry was made into the table. When a client at a node calls msg_send, and if an entry for the destination node already exists in the routing table, ODR first checks that the routing information is not ‘stale’. A stale routing table entry is one that is older than the value defined by the staleness parameter given as a command line argument to the ODR process when it is executed. ODR deletes stale entries (as well as non-stale entries when the flag parameter in msg_send is set) and initiates a route rediscovery by issuing a RREQ for the destination node. This will force periodic updating of the routing tables to take care of failed nodes along the current path, Ethernet addresses that might have changed, and so on. Similarly, as RREQs propagate through the intranet, existing stale table entries at intermediate nodes are deleted and new route discoveries propagated. As noted above when discussing the processing of RREQs and RREPs, the associated timestamp for an existing table entry is updated in response to having the route either “reconfirmed” or updated (this applies to both reverse routes, by virtue of RREQs received, and to forward routes, by virtue of RREPs). Finally, note that a staleness parameter of 0 essentially indicates that the discovered route will be used only once, when first discovered, and then discarded. Effectively, an ODR with staleness parameter 0 maintains no real routing table at all ; instead, it forces route discoveries at every step of its operation. As a practical matter, ODR should be run with staleness parameter values that are considerably larger than the longest RTT on the intranet, otherwise performance will degrade considerably (and collapse entirely as the parameter values approach 0). Nevertheless, for robustness, we need to implement a mechanism by which an intermediate node that receives a RREP or application payload message for forwarding and finds that its relevant routing table entry has since gone stale, can intiate a RREQ to rediscover the route it needs. RREQ, RREP, and time client/server request/response messages will all have to be carried as encapsulated ODR protocol messages that form the data payload of Ethernet frames. So we need to design the structure of ODR protocol messages. The format should contain a type field (0 for RREQ, 1 for RREP, 2 for application payload ). The remaining fields in an ODR message will depend on what type it is. The fields needed for (our simplified versions of AODV’s) RREQ and RREP should be fairly clear to you, but keep in mind that you need to introduce two extra fields: The “RREP already sent” bit or field in RREQ messages, as mentioned above. A “forced discovery” bit or field in both RREQ and RREP messages: When a client application forces route rediscovery, this bit should be set in the RREQ issued by the client node ODR. Intermediate nodes that are not the destination node but which do have a route to the destination node should not respond with RREPs to an RREQ which has the forced discovery field set. Instead, they should continue to flood the RREQ so that it eventually reaches the destination node which will then respond with an RREP. The intermediate nodes relaying such an RREQ must update their ‘reverse’ route back to the source node accordingly, even if the new route is less efficient (i.e., has more hops) than the one they currently have in their routing table. The destination node responds to the RREQ with an RREP in which this field is also set. Intermediate nodes that receive such a forced discovery RREP must update their ‘forward’ route to the destination node accordingly, even if the new route is less efficient (i.e., has more hops) than the one they currently have in their routing table. This behaviour will cause a forced discovery RREQ to be responded to only by the destination node itself and not any other node, and will cause intermediate nodes to update their routing tables to both source and destination nodes in accordance with the latest routing information received, to cover the possibility that older routes are no longer valid because nodes and/or links along their paths have gone down. A type 2, application payload, message needs to contain the following type of information : type = 2 ‘canonical’ IP address of source node ‘port’ number of source application process (This, of course, is not a real port number in the TCP/UDP sense, but simply a value that ODR at the source node uses to designate the sun_path name for the source application’s domain socket.) ‘canonical’ IP address of destination node ‘port’ number of destination application process (This is passed to ODR by the application process at the source node when it calls msg_send. Its designates the sun_path name for an application’s domain socket at the destination node.) hop count (This starts at 0 and is incremented by 1 at each hop so that ODR can make use of the message to update its routing table, as discussed above.) number of bytes in application message The fields above essentially constitute a ‘header’ for the ODR message. Note that fields which you choose to have carry numeric values (rather than ascii characters, for example) must be in network byte order. ODR-defined numeric-valued fields in type 0, RREQ, and type 1, RREP, messages must, of course, also be in network byte order. Also note that only the ‘canonical’ IP addresses are used for the source and destination nodes in the ODR header. The same has to be true in the headers for type 0, RREQ, and type 1, RREP, messages. The general rule is that ODR messages only carry ‘canonical’ IP node addresses. The last field in the type 2 ODR message is essentially the data payload of the message. application message given in the call to msg_send An ODR protocol message is encapsulated as the data payload of an Ethernet frame whose header it fills in as follows : source address = Ethernet address of outgoing interface of the current node where ODR is processing the message. destination address = Ethernet broadcast address for type 0 messages; Ethernet address of next hop node for type 1 & 2 messages. protocol field = protocol value for the ODR PF_PACKET socket(s). Last but not least, whenever ODR writes an Ethernet frame out through its socket, it prints out on stdout the message ODR at node vm i1 : sending frame hdr src vm i1 dest addr ODR msg type n src vm i2 dest vm i3 where addr is in presentation format (i.e., hexadecimal xx:xx:xx:xx:xx:xx) and gives the destination Ethernet address in the outgoing frame header. Other nodes in the message should be identified by their vm name. A message should be printed out for each packet sent out on a distinct interface. ODR and the API When the ODR process first starts, it must construct a table in which it enters all well-known ‘port’ numbers and their corresponding sun_path names. These will constitute permanent entries in the table. Thereafter, whenever it reads a message off its domain socket, it must obtain the sun_path name for the peer process socket and check whether that name is entered in the table. If not, it must select an ‘ephemeral’ ‘port’ value by which to designate the peer sun_path name and enter the pair < port value , sun_path name > into the table. Such entries cannot be permanent otherwise the table will grow unboundedly in time, with entries surviving for ever, beyond the peer processes’ demise. We must associate a time_to_live field with a non-permanent table entry, and purge the entry if nothing is heard from the peer for that amount of time. Every time a peer process for which a non-permanent table entry exists communicates with ODR, its time_to_live value should be reinitialized. Note that when ODR writes to a peer, it is possible for the write to fail because the peer does not exist : it could be a ‘well-known’ service that is not running, or we could be in the interval between a process with a non-permanent table entry terminating and the expiration of its time_to_live value. Notes A proper implementation of ODR would probably require that RREQ and RREP messages be backed up by some kind of timeout and retransmission mechanism since the network transmission environment is not reliable. This would considerably complicate the implementation (because at any given moment, a node could have multiple RREQs that it has flooded out, but for which it has still not received RREPs; the situation is further complicated by the fact that not all intermediate nodes receiving and relaying RREQs necessarily lie on a path to the destination, and therefore should expect to receive RREPs), and, learning-wise, would not add much to the experience you should have gained from Assignment 2.

Communication Skills Have you ever attempted to convey the desired information? Maybe you took a stab at pitching an earth shattering venture, you were tasked with running a departmental meeting, or you expected to convey a convincing presentation.

So control the circumstance, exhibit ability, and console your collaborators that you're acting sincerely and transparently.

I was having a hard time finding something to analyze spectrograph data for LabChart8, so I made this. It counts the number of each type of wave then gives you the power for each. It's helpful if you want to collect data to compare the types of waves and their powers. You need to have exported the spectrograph data as a spectrograph PSD, and it will give out (1) text file for all the waves and how many times they appear in the sample, (2) a separate text file for all the powers of each wave separately, and (3) a plot of each. I'm really sorry, I couldn't figure out how to merge them, as I'm somewhat new to MATLAB. This code has bugs, so please let me know if you have any tips and I fix it as soon as possible:) You can import the text onto Google Sheets or Excel for further analysis. Parameters: alpha (between 8 to 13 Hz; average amplitudes of 30 to 50 μV peak-to-peak) beta (13 to 30 Hz; <20 μV peak-to-peak) theta (4 and 8 Hz; <30 μV peak-to-peak) delta (0.5 and 4 Hz; up to 100 - 200 μV peak-to-peak) gamma (30 and 50 Hz) Table outputs, all seperate files: (1) AlphaPower (2) BetaPower (3) DeltaPower (4) GammaPower (5) ThetaPower Again, you will have to import this into google sheets if you want to combine all of them.

To evaluate the working and key benefits of the proposed S+ Mobile Network architecture, we developed an ns–3-based system level simulation test setup, which primarily consists of point to point helper, network, applications, mobility and core modules. Besides this, OFSwitch13 module [23] has been implemented in ns-3 simulator that enable support for OpenFlow protocol version 1.3. we extended the NS3 environment to implement instantiation of multiple DPEs and modified the currently deployed X2-based handover procedure of the NS3 to support relocation of DPE during the MUs handover. It implements the messages exchange between the different network functions for inter-system handover and DPE relocation enforcing the policies and the behaviour described in section 5.1 and 5.2. The source code of implemented modules is available via [24]. The logical network topology of the evaluation scenario is shown in Figure 4. The simulation starts with a MU initially attached to the PDN service 1 via 3GPP compliant access network. Moving out of S+ eNB coverage area the MU discovers and switches to non- 3GPP compliant access connection. We set the parameters for simulation in which data packets are set to 1000 units and simulation interval is 10ms. For each handover case, we measured the preparation, interruption and completion time. Figures 8a and 8b depicts the measured handover execution time,

How to share data with a statistician This is a guide for anyone who needs to share data with a statistician or data scientist. The target audiences I have in mind are: Collaborators who need statisticians or data scientists to analyze data for them Students or postdocs in various disciplines looking for consulting advice Junior statistics students whose job it is to collate/clean/wrangle data sets The goals of this guide are to provide some instruction on the best way to share data to avoid the most common pitfalls and sources of delay in the transition from data collection to data analysis. The Leek group works with a large number of collaborators and the number one source of variation in the speed to results is the status of the data when they arrive at the Leek group. Based on my conversations with other statisticians this is true nearly universally. My strong feeling is that statisticians should be able to handle the data in whatever state they arrive. It is important to see the raw data, understand the steps in the processing pipeline, and be able to incorporate hidden sources of variability in one's data analysis. On the other hand, for many data types, the processing steps are well documented and standardized. So the work of converting the data from raw form to directly analyzable form can be performed before calling on a statistician. This can dramatically speed the turnaround time, since the statistician doesn't have to work through all the pre-processing steps first. What you should deliver to the statistician To facilitate the most efficient and timely analysis this is the information you should pass to a statistician: The raw data. A tidy data set A code book describing each variable and its values in the tidy data set. An explicit and exact recipe you used to go from 1 -> 2,3 Let's look at each part of the data package you will transfer. The raw data It is critical that you include the rawest form of the data that you have access to. This ensures that data provenance can be maintained throughout the workflow. Here are some examples of the raw form of data: The strange binary file your measurement machine spits out The unformatted Excel file with 10 worksheets the company you contracted with sent you The complicated JSON data you got from scraping the Twitter API The hand-entered numbers you collected looking through a microscope You know the raw data are in the right format if you: Ran no software on the data Did not modify any of the data values You did not remove any data from the data set You did not summarize the data in any way If you made any modifications of the raw data it is not the raw form of the data. Reporting modified data as raw data is a very common way to slow down the analysis process, since the analyst will often have to do a forensic study of your data to figure out why the raw data looks weird. (Also imagine what would happen if new data arrived?) The tidy data set The general principles of tidy data are laid out by Hadley Wickham in this paper and this video. While both the paper and the video describe tidy data using R, the principles are more generally applicable: Each variable you measure should be in one column Each different observation of that variable should be in a different row There should be one table for each "kind" of variable If you have multiple tables, they should include a column in the table that allows them to be joined or merged While these are the hard and fast rules, there are a number of other things that will make your data set much easier to handle. First is to include a row at the top of each data table/spreadsheet that contains full row names. So if you measured age at diagnosis for patients, you would head that column with the name AgeAtDiagnosis instead of something like ADx or another abbreviation that may be hard for another person to understand. Here is an example of how this would work from genomics. Suppose that for 20 people you have collected gene expression measurements with RNA-sequencing. You have also collected demographic and clinical information about the patients including their age, treatment, and diagnosis. You would have one table/spreadsheet that contains the clinical/demographic information. It would have four columns (patient id, age, treatment, diagnosis) and 21 rows (a row with variable names, then one row for every patient). You would also have one spreadsheet for the summarized genomic data. Usually this type of data is summarized at the level of the number of counts per exon. Suppose you have 100,000 exons, then you would have a table/spreadsheet that had 21 rows (a row for gene names, and one row for each patient) and 100,001 columns (one row for patient ids and one row for each data type). If you are sharing your data with the collaborator in Excel, the tidy data should be in one Excel file per table. They should not have multiple worksheets, no macros should be applied to the data, and no columns/cells should be highlighted. Alternatively share the data in a CSV or TAB-delimited text file. (Beware however that reading CSV files into Excel can sometimes lead to non-reproducible handling of date and time variables.) The code book For almost any data set, the measurements you calculate will need to be described in more detail than you can or should sneak into the spreadsheet. The code book contains this information. At minimum it should contain: Information about the variables (including units!) in the data set not contained in the tidy data Information about the summary choices you made Information about the experimental study design you used In our genomics example, the analyst would want to know what the unit of measurement for each clinical/demographic variable is (age in years, treatment by name/dose, level of diagnosis and how heterogeneous). They would also want to know how you picked the exons you used for summarizing the genomic data (UCSC/Ensembl, etc.). They would also want to know any other information about how you did the data collection/study design. For example, are these the first 20 patients that walked into the clinic? Are they 20 highly selected patients by some characteristic like age? Are they randomized to treatments? A common format for this document is a Word file. There should be a section called "Study design" that has a thorough description of how you collected the data. There is a section called "Code book" that describes each variable and its units. How to code variables When you put variables into a spreadsheet there are several main categories you will run into depending on their data type: Continuous Ordinal Categorical Missing Censored Continuous variables are anything measured on a quantitative scale that could be any fractional number. An example would be something like weight measured in kg. Ordinal data are data that have a fixed, small (< 100) number of levels but are ordered. This could be for example survey responses where the choices are: poor, fair, good. Categorical data are data where there are multiple categories, but they aren't ordered. One example would be sex: male or female. This coding is attractive because it is self-documenting. Missing data are data that are unobserved and you don't know the mechanism. You should code missing values as NA. Censored data are data where you know the missingness mechanism on some level. Common examples are a measurement being below a detection limit or a patient being lost to follow-up. They should also be coded as NA when you don't have the data. But you should also add a new column to your tidy data called, "VariableNameCensored" which should have values of TRUE if censored and FALSE if not. In the code book you should explain why those values are missing. It is absolutely critical to report to the analyst if there is a reason you know about that some of the data are missing. You should also not impute/make up/ throw away missing observations. In general, try to avoid coding categorical or ordinal variables as numbers. When you enter the value for sex in the tidy data, it should be "male" or "female". The ordinal values in the data set should be "poor", "fair", and "good" not 1, 2 ,3. This will avoid potential mixups about which direction effects go and will help identify coding errors. Always encode every piece of information about your observations using text. For example, if you are storing data in Excel and use a form of colored text or cell background formatting to indicate information about an observation ("red variable entries were observed in experiment 1.") then this information will not be exported (and will be lost!) when the data is exported as raw text. Every piece of data should be encoded as actual text that can be exported. The instruction list/script You may have heard this before, but reproducibility is a big deal in computational science. That means, when you submit your paper, the reviewers and the rest of the world should be able to exactly replicate the analyses from raw data all the way to final results. If you are trying to be efficient, you will likely perform some summarization/data analysis steps before the data can be considered tidy. The ideal thing for you to do when performing summarization is to create a computer script (in R, Python, or something else) that takes the raw data as input and produces the tidy data you are sharing as output. You can try running your script a couple of times and see if the code produces the same output. In many cases, the person who collected the data has incentive to make it tidy for a statistician to speed the process of collaboration. They may not know how to code in a scripting language. In that case, what you should provide the statistician is something called pseudocode. It should look something like: Step 1 - take the raw file, run version 3.1.2 of summarize software with parameters a=1, b=2, c=3 Step 2 - run the software separately for each sample Step 3 - take column three of outputfile.out for each sample and that is the corresponding row in the output data set You should also include information about which system (Mac/Windows/Linux) you used the software on and whether you tried it more than once to confirm it gave the same results. Ideally, you will run this by a fellow student/labmate to confirm that they can obtain the same output file you did. What you should expect from the analyst When you turn over a properly tidied data set it dramatically decreases the workload on the statistician. So hopefully they will get back to you much sooner. But most careful statisticians will check your recipe, ask questions about steps you performed, and try to confirm that they can obtain the same tidy data that you did with, at minimum, spot checks. You should then expect from the statistician: An analysis script that performs each of the analyses (not just instructions) The exact computer code they used to run the analysis All output files/figures they generated. This is the information you will use in the supplement to establish reproducibility and precision of your results. Each of the steps in the analysis should be clearly explained and you should ask questions when you don't understand what the analyst did. It is the responsibility of both the statistician and the scientist to understand the statistical analysis. You may not be able to perform the exact analyses without the statistician's code, but you should be able to explain why the statistician performed each step to a labmate/your principal investigator.

The first thing to understand is that we are NOT looking for anything overelaborate or that would be exceptionally difficult to implement. If there are aspects of what we are suggesting that appear to you to be technically complex or problematic, please advise. We are less concerned about absolute perfection or smoothness as we are about having a clean Web site that operates effectively, works with a broad spectrum of browsers and devices, of varying compute power, and isn't difficult for the user to navigate. The second thing is that the overall design - as you may have seen - is based on the 'Koch Curve', a fractal figure that at any scale has the same properties. What our thinking is, is that the site will be navigated for the most part by 'descending' through the curve, that is, effectively zooming in to the next level of detail. With that in mind, the animation effect we are trying to achieve is not one of constant-size figures moving around on a 2-D surface, but rather the impression of zooming into a static figure. One of the main advantages of this approach for us is that it is a completely scalable design, that is to say, as the company grows, we can add pages simply by adding another hierarchical level and zooming in to the next level. At the same time, because zooming in, at any level beyond the top, produces exactly the same figure, only a few graphical templates are required, which can be endlessly replicated as one descends down. For the moment, only the very top level and one level of hierarchical depth will exist, but later, this could be expanded, again, by replication of the existing templates. The top level is, obviously, different from all the other levels because it's where the recursion 'tops out'. This is the level that shows the 'star' surrounded by the first depth level below it as background 'leaves'. When entering the site at the homepage, these surrounding leaves should be grey; this is a graphical way of hinting at another level of expansion whilst indicating, through the fact that the star's points are in a saturated colour, that this is the level that's active. Whether at the top level or at subsequent levels, the idea is that the 'point' pointing straight up represents the currently active area. At the homepage, initially, there isn't an active area as such, it's just a means to navigate down to areas which have content. Whatever graphical elements are in the most saturated colour, are clickable, and each point that can be clicked represents a sub-page. If the point clicked is already on top, then the figure just does a straightforward 'zoom' into the next level. But if an off-axis point is clicked, it has to be placed on top. So the idea is that at any level of zoom, the figure rotates first so that the selected point is on top, then zooms into the next level. During the zoom process, the next level of hierarchy - the next group of 'leaves' - appears for the now-zoomed area. Note that because these figures are self-similar at all scales, all zooms can be achieved by simple rotations and scalings of the same figure set, it's not going to be a separate graphic template for each sub-page. Also, if you hover over a point at the 'active' level (the one that's in a saturated colour), the next level of subpoints (the next 'leaf') should appear over the point. This allows the user to hover and see what they could access by clicking a given point. All points have text labels, these go on the interior of the point. Meanwhile, once you're below the top level (home page), clicking on the exterior point (the largest one sitting at the bottom of the page, in a semi-saturated colour), lets you 'pop' a level, returning to the previous scale. This is nothing more than a reverse zoom, and since only the centre point is involved, there's never any rotation, the zoom-in effect is simply run 'backwards'. Once you reach a page with content, the screen splits into 2 panes; the left-hand pane contains the figure as always, at the active zoom level, the right-hand pane contains the text content (with any graphics, etc. that may be on it) set on a slate grey background. For mobile users, only the content page should appear, but with the black triangle (which could have a 'hamburger' symbol in its centre to make it clear what this does) in the top right. Tapping the triangle will bring you back to what would be the left pane on a desktop or laptop machine, essentially, the navigation section. It would be fine to have any 'hamburger' navigation in mobile mode let you navigate directly to a page via a menu-like series of options - this conforms to what users will expect. And so we get back to that black triangle, the one element that stays on every page. Its scale never changes, and it always serves the same purpose: global navigation. The idea is that clicking the black triangle gives you the option either to a) return to the main page or b) open a menu of all pages that lets you skip directly to them. (Later, we may also allow a third option, which would allow any form data to be cleared, but this only makes sense once the site reaches the point where there is even a form that could be filled, and for the moment we do NOT have any forms. That's potential future functionality). At the home page only, the black triangle is directly in the centre of the page, but on each subsequent level, it sits centred at the bottom of the page. All of these graphics should be vector format, not bitmaps, especially since we're scaling everything. A set of background SVGs should probably do it quite nicely. I have been very detailed in describing how this is intended to work to try to avoid ambiguity, but once again I want to emphasise that the overall effect and idea we are looking for is really quite simple - please do not be intimidated by the lengthy description, it's only long so as to be as precise as possible. Please contact me if you have further questions. Thank you,

While your data companions rushed off to jobs in finance and government, you remained adamant that science was the way for you. Staying true to your mission, you've joined Pymaceuticals Inc., a burgeoning pharmaceutical company based out of San Diego. Pymaceuticals specializes in anti-cancer pharmaceuticals. In its most recent efforts, it began screening for potential treatments for squamous cell carcinoma (SCC), a commonly occurring form of skin cancer. As a senior data analyst at the company, you've been given access to the complete data from their most recent animal study. In this study, 249 mice identified with SCC tumor growth were treated through a variety of drug regimens. Over the course of 45 days, tumor development was observed and measured. The purpose of this study was to compare the performance of Pymaceuticals' drug of interest, Capomulin, versus the other treatment regimens. You have been tasked by the executive team to generate all of the tables and figures needed for the technical report of the study. The executive team also has asked for a top-level summary of the study results. ## Instructions Your tasks are to do the following: * Before beginning the analysis, check the data for any mouse ID with duplicate time points and remove any data associated with that mouse ID. * Use the cleaned data for the remaining steps. * Generate a summary statistics table consisting of the mean, median, variance, standard deviation, and SEM of the tumor volume for each drug regimen. * Generate a bar plot using both Pandas's `DataFrame.plot()` and Matplotlib's `pyplot` that shows the number of total mice for each treatment regimen throughout the course of the study. * **NOTE:** These plots should look identical. * Generate a pie plot using both Pandas's `DataFrame.plot()` and Matplotlib's `pyplot` that shows the distribution of female or male mice in the study. * **NOTE:** These plots should look identical. * Calculate the final tumor volume of each mouse across four of the most promising treatment regimens: Capomulin, Ramicane, Infubinol, and Ceftamin. Calculate the quartiles and IQR and quantitatively determine if there are any potential outliers across all four treatment regimens. * Using Matplotlib, generate a box and whisker plot of the final tumor volume for all four treatment regimens and highlight any potential outliers in the plot by changing their color and style. **Hint**: All four box plots should be within the same figure. Use this [Matplotlib documentation page](https://matplotlib.org/gallery/pyplots/boxplot_demo_pyplot.html#sphx-glr-gallery-pyplots-boxplot-demo-pyplot-py) for help with changing the style of the outliers. * Select a mouse that was treated with Capomulin and generate a line plot of tumor volume vs. time point for that mouse. * Generate a scatter plot of mouse weight versus average tumor volume for the Capomulin treatment regimen. * Calculate the correlation coefficient and linear regression model between mouse weight and average tumor volume for the Capomulin treatment. Plot the linear regression model on top of the previous scatter plot. * Look across all previously generated figures and tables and write at least three observations or inferences that can be made from the data. Include these observations at the top of notebook. Here are some final considerations: * You must use proper labeling of your plots, to include properties such as: plot titles, axis labels, legend labels, _x_-axis and _y_-axis limits, etc.

# Matplotlib Homework - The Power of Plots ## Background What good is data without a good plot to tell the story? So, let's take what you've learned about Python Matplotlib and apply it to a real-world situation and dataset:  While your data companions rushed off to jobs in finance and government, you remained adamant that science was the way for you.

Be patient with yourself as you trudge through these problems. They will take time and there is no shame in fumbling along the way. Data visualization is equal parts exploration, equal parts resolution. * You have been provided a starter notebook. Use the code comments as a reminder of steps to follow as you complete the assignment. * Don't get bogged down in small details. Always focus on the big picture. If you can't figure out how to get a label to show up correctly, come back to it. Focus on getting the core skeleton of your notebook complete. You can always revisit old problems. * While you are trying to complete this assignment, feel encouraged to constantly refer to Stack Overflow and the Pandas documentation. These are needed tools in every data analyst's tool belt. * Remember, there are many ways to approach a data problem. The key is to break up your task into micro tasks. Try answering questions like: * How does my DataFrame need to be structured for me to have the right _x_-axis and _y_-axis? * How do I build a basic scatter plot? * How do I add a label to that scatter plot? * Where would the labels for that scatter plot come from? Again, don't let the magnitude of a programming task scare you off. Ultimately, every programming problem boils down to a handful of bite-sized tasks. * Get help when you need it! There is never any shame in asking. But, as always, ask a _specific_ question. You'll never get a great answer to "I'm lost." ### Copyright Trilogy Education Services © 2020. All Rights Reserved.

Introduction It is now possible to collect a large amount of data about personal movement using activity monitoring devices such as a Fitbit, Nike Fuelband, or Jawbone Up. These type of devices are part of the “quantified self” movement – a group of enthusiasts who take measurements about themselves regularly to improve their health, to find patterns in their behavior, or because they are tech geeks. But these data remain under-utilized both because the raw data are hard to obtain and there is a lack of statistical methods and software for processing and interpreting the data. This assignment makes use of data from a personal activity monitoring device. This device collects data at 5 minute intervals through out the day. The data consists of two months of data from an anonymous individual collected during the months of October and November, 2012 and include the number of steps taken in 5 minute intervals each day. The data for this assignment can be downloaded from the course web site: Dataset: Activity monitoring data [52K] The variables included in this dataset are: steps: Number of steps taking in a 5-minute interval (missing values are coded as NA) date: The date on which the measurement was taken in YYYY-MM-DD format interval: Identifier for the 5-minute interval in which measurement was taken The dataset is stored in a comma-separated-value (CSV) file and there are a total of 17,568 observations in this dataset.

You will need to write a report that answers the questions detailed below. Ultimately, you will need to complete the entire assignment in a single R markdown document that can be processed by knitr and be transformed into an HTML file. Throughout your report make sure you always include the code that you used to generate the output you present. When writing code chunks in the R markdown document, always use echo = TRUE so that someone else will be able to read the code. This assignment will be evaluated via peer assessment so it is essential that your peer evaluators be able to review the code for your analysis.

Loading and preprocessing the data Show any code that is needed to Load the data (i.e. read.csv()) Process/transform the data (if necessary) into a format suitable for your analysis What is mean total number of steps taken per day? For this part of the assignment, you can ignore the missing values in the dataset. Calculate the total number of steps taken per day If you do not understand the difference between a histogram and a barplot, research the difference between them. Make a histogram of the total number of steps taken each day Calculate and report the mean and median of the total number of steps taken per day What is the average daily activity pattern? Make a time series plot (i.e. type = "l") of the 5-minute interval (x-axis) and the average number of steps taken, averaged across all days (y-axis) Which 5-minute interval, on average across all the days in the dataset, contains the maximum number of steps? Imputing missing values Note that there are a number of days/intervals where there are missing values (coded as NA). The presence of missing days may introduce bias into some calculations or summaries of the data. Calculate and report the total number of missing values in the dataset (i.e. the total number of rows with NAs) Devise a strategy for filling in all of the missing values in the dataset. The strategy does not need to be sophisticated. For example, you could use the mean/median for that day, or the mean for that 5-minute interval, etc. Create a new dataset that is equal to the original dataset but with the missing data filled in. Make a histogram of the total number of steps taken each day and Calculate and report the mean and median total number of steps taken per day. Do these values differ from the estimates from the first part of the assignment? What is the impact of imputing missing data on the estimates of the total daily number of steps? Are there differences in activity patterns between weekdays and weekends? For this part the weekdays() function may be of some help here. Use the dataset with the filled-in missing values for this part. Create a new factor variable in the dataset with two levels – “weekday” and “weekend” indicating whether a given date is a weekday or weekend day. Make a panel plot containing a time series plot (i.e. type = "l") of the 5-minute interval (x-axis) and the average number of steps taken, averaged across all weekday days or weekend days (y-axis).
