Wednesday, October 21st, 2015, 7.49am.

The screen fades into opening credits.

The Back to the Future Part IV logo appears on the screen and the Back to the Future theme tune is heard.

The camera flies around an early morning 2015 landscape of Hill Valley taking in the sites of the town including Courthouse Square and the Clock Tower. The opening credits appear during this scene. The camera eventually heads down a street and eventually ends up at the McFly household before fading to black.

A clock starts kicking and Wednesday, October 21st, 2015, 7.49am appears and fades.

A clock is shown on the wall in Scott's bedroom. The camera pans down to an alarm clock on the bedside cabinet. The clock switched to 7.50am and an alarm goes off; Scott groans and then gets up out of bed.

Scott, now dressed, heads along the upstairs landing of the house carrying his skateboard. He pauses at the corner when he hears his sister Marlene McFly, aged 19, talking to their brother Marty Junior, aged 17.

MARLENE

Stay away from him Marty; you'll end up in so much trouble. You know Griff Tannen is bad news.

MARTY JUNIOR

But Marlene, you know what he's like...

MARLENE

He's just a bully. You need to stand up to him.

MARTY JUNIOR

You know I hate confrontations. Stop nagging me sis'.

MARLENE

I'm only "nagging" you because I care about you. You're my twin brother and you mean everything to me. If you end up copping the flak for Griff Tannen I don't know what I'd do.

Scott comes into view and the two siblings end their conversation.

SCOTT

Morning bro, morning sis, don't stop on my account.

Scott carries on walking towards the living room, something his brother and sister said makes him look puzzled. He shakes his head and continues.

In the dining room. Marty Senior and Jennifer are having breakfast.

JENNIFER

I know today's the day Marty; we've just got to act like we don't know what's going on.

MARTY SENIOR

If we intervene in anyway it could cause one of those paradoxes Doc used to go on about.

JENNIFER

But we don't live in Hilldale anymore. It's all going to be different.

MARTY SENIOR

Some alternate version of what happened is bound to happen, once today is over, it's all over, we can get on with our lives.

JENNIFER

I'm nervous about seeing myself aged seventeen again.

MARTY SENIOR

Well you know if it happens, you know what to do. Just cry 'I'm young' before pretending to faint...

Scott enters into the room and Marty shuts up. He has that puzzled look on his face again after catching the end of the conversation.

Jennifer acts all nervous.

JENNIFER

Good morning sweetheart, did you sleep well?

SCOTT

Yeah fine Mom.

MARTY SENIOR

You all right son? You look a bit perplexed.

SCOTT

I'm okay Dad; I just slept awkwardly. I'll just go off to school.

JENNIFER

You haven't had any breakfast Scott; you know it's the most important meal of the day.

SCOTT

I'm gonna grab something at the Café 80s on the way. I'm meeting friends.

Marty Senior snaps.

MARTY SENIOR

The Café 80s?

Scott replies sarcastically.

SCOTT

Yeah, the place on the Old Courthouse Square, opposite the mall, the one that has the old 1980s retro feel about it.

MARTY SENIOR

Hey cut it out son, there's no need for that. I only asked.

Marty pauses thoughtfully for a moment.

MARTY SENIOR

Listen son, when you finish school this afternoon, I want you to go round your Grandma and Grandpa Parker's straight away.

Scott's not buying it.

SCOTT Why?

MARTY SENIOR

They're expecting you. They'll have dinner ready for you.

SCOTT

I thought Grandma and Grandpa McFly were coming here for dinner after Grandpa comes back from his golf. We were going to have pizza.

Jennifer thinks quickly.

JENNIFER

Grandpa Parker wants you to do some odd jobs for him, that's why you've got to go after school. You can have pizza with me later on, as I've got to work late.

Scott pulls a face.

SCOTT

Whatever. See y'all later.

Scott leaves the house and skateboards down the road.

Scott arrives outside his friend Eric's house on his skateboard. He stops, kicks the board up and catches it. Eric Wilson, aged 15, comes out of his house also carrying a skateboard.

ERIC

Yo, McFly, how's it hanging?

SCOTT

Hey Eric. This is it! Today's the day!

Eric is puzzled.

ERIC

Today's what day?

SCOTT

The day in my Dad's story. The day he comes here to 2015 from 1985. You know, when he was 17 and had the time machine.

Eric rolls his eyes.

ERIC

You're not still going on about that story. You've been going on about it for best part of the year now.

SCOTT

But you don't understand. Some of the stuff in the story ties up with stuff that's happening. He wrote that story nearly thirty years ago.

ERIC

What stuff? Has my big brother started converting cars so they can fly? We could go for a fly around town! Gimme a break Scotty, it's just some story which your Dad wrote to boost his flagging music career.

SCOTT

His career isn't flagging; he's got a greatest hits album coming out in...

Eric butts in.

ERIC

Yeah, whatever Scotty. If any of it is happening, it's just coincidence. Your dad got lucky guessing my dad and brother's names. It was an obvious choice for Mayor Goldie Wilson to have a son called Goldie Wilson Junior who would become mayor, and yet another obvious choice for his son to be called Goldie Wilson III.

SCOTT

Your brother works with cars though doesn't he?

ERIC

Yes, but I haven't seen any of them fly yet. Your dad's story was all about flying cars and hoverboards and stuff like that. How do you explain that then? Imagine that, (chuckling) flying cars in 2015? I think your dad's imagination was running away with him when he thought up that one. Can you see any cars flying around Scotty?

Scott stands there looking deflated. A regular car drives past them with all four wheels firmly on the ground.

SCOTT

Something must have changed. Anyway, hear me out. I heard my sister telling my brother to stay away from Griff Tannen this morning, and in the story my Dad comes from the past to stop Griff getting Marty into trouble with the law. And my Mom and Dad were pretty insistent about me being out the way after school when it's all supposed to kick off.

ERIC

Yeah, yeah. You're a dreamer McFly. Come on if we want to get something to eat before school, we'd better hurry. If only we had a 'hoverboard'; we'd get to the Café 80s much quicker.

Scott glares at Eric as he mounts his skateboard and heads off down the road. Scott gets on his board and skates after him.

At Hill Valley High School, Scott and Eric arrive on their skateboards. Many students are walking around. The school has been cleaned up a lot since 1985. Outside the school is a statue of Mr. Strickland, the old principal of the school. Scott and Eric dismount their skateboards and walk up the steps towards the school. A group of girls come out of the school and Scott accidentally catches the bag of one of the girls, Suzy Lee aged 15. This causes her to drop the books she's carrying. Suzy snaps.

SUZY

Hey watch it!

Scott apologises.

SCOTT

Sorry, it was an accident.

Scott helps Suzy pick her belonging up in silence. Afterwards, Suzy glares at Scott and leaves the scene with her friends.

ERIC

That Suzy Lee is one hot babe. I wouldn't mind a piece of her. She doesn't like you much does she?

SCOTT

She still hasn't forgiven me for accidentally setting fire to her hair in Science class last year.

ERIC

Bad move dude. I reckon she likes you. If you play your cards right.

SCOTT

What do you mean "likes" me? You just saw the way she looked at me.

ERIC

She wants you buddy.

SCOTT

Quit daydreaming Wilson. She hates me, and as far as I'm concerned, the feelings mutual.

ERIC

Whatever dude.

Inside the School, Scott and Eric head walk along the corridor.

GRIFF TANNEN Hey McFly!

Scott and Eric turn round to see Griff Tannen, aged 19, the local bully accompanied by his gang. The gang consists of Data, who has face paints on, Spike, the female, and Whitey. Scott thinks Griff is talking to him, but instead Griff focuses his attention a little way past him. Scott notices his brother, Marty Junior a little way along the corridor behind him. Griff and his gang pull Marty Junior aside. Scott and Eric hang in the shadows nervously.

MARTY JUNIOR

Oh, hi Griff how are ya doing?

GRIFF

McFly, you haven't got back to me about that little business proposition I had for ya. I need an answer off ya. Tonight's the big night remember.

MARTY JUNIOR

Um, well yeah Griff...

A teacher comes around the corner.

TEACHER

Griff Tannen, what are you doing in the school, you left last year. Come to catch up on some of the study you missed out on?

GRIFF

I was just paying my little buddy McFly a visit.

TEACHER

You were just leaving, come on out the lot of you.

GRIFF

Okay, okay, we're going, hey McFly I want an answer from you. Be at the Café 80s tonight 5pm. Don't be late.

Griff's gang head out of the school laughing knocking books out of a younger students arms on the way out. The teacher heads off into a classroom and Marty Junior heads off in another direction looking worried.

At the end of the corridor Scott has punched up his Dad's story on his iPhone.

SCOTT

There you go, Griff meets Marty at the Café 80s this evening. He tries to bully Marty into taking part in a robbery, and my Dad pretending to be him comes from 1985 to sort it all out to stop the family falling apart.

ERIC

So where are you supposed to fit into all this?

SCOTT

I don't, I wasn't even born.

ERIC

Your story is getting weirder.

SCOTT

At the end of the story, Dad goes on about how he was in a drag race in 1985 with some kid from his school, where he crashed his 4 by 4 into a Rolls Royce, broke his hand and couldn't pursue a music career. Anyway after all his time travelling adventures he learnt a lesson about not rising to people who called him chicken, and backed out of the race when the event came around. He then went on to get married, write great music, become famous and because Mom and Dad were well off they had three kids instead of two. That's why

I'm here now but wasn't here then. Something else must've changed to stop all the cars flying and stuff. You've gotta come to the Café 80s later with me to find out one way or another if this is real or not.

ERIC

Anything for a quiet life.

The bell rings and all the kids head off into classrooms.

In their classroom, Scott, Eric, Suzy and other students are having a history lesson. All the kids are sitting at desks with computer terminals on them. The teacher, Mr. Arky is taking the class.

MR. ARKY

Okay, I need you all to get into pairs for your assignment on the history of Hill Valley. Over the next couple of weeks you will be working together exploring clues to the past in the town and looking at ways the town has changed over the last century and a half, since the settlement was founded. This assignment will go toward your final grade at the end of the year so I want you all to bear that in mind before you all decide it's boring and you don't want to do it.

Right, could you all choose a partner and do it quietly please?

The kids all move around the classroom getting into their pairs. Eric moves over to sit with Scott.

MR. ARKY

Eric Wilson I think you'd be better off working away from Scott McFly. You may be son of the mayor but I think you'd do better on the assignment without the distraction of talking about skateboarding and rock music.

ERIC

Aww, sir.

MR. ARKY

No 'aww' about it Eric, I think you should work with Amy. Could you go and sit with her please.

SUZY

That's not fair sir, I want to work with Amy. We haven't done anything wrong; I don't see why we have to be split up because two others can't work together without getting into trouble.

MR. ARKY

I'm sorry Suzy but that's the way it is. Could you move over and sit with Scott. I think you'll make a great pair for this assignment.

SUZY

Fat chance.

Eric and Suzy swap places. Suzy sits next to Scott and the pair of them fold their arms and sit facing away from each other with a look of protest on their faces.

In the Corridor of school, the end of lesson bell sounds and Scott and Eric come out of the classroom. Suzy and Amy follow them.

SUZY

Hey wait up.

SCOTT

What's up?

SUZY

Amy and I are starting the assignment after school. Do you two want to come along and help out?

SCOTT

I've got to be somewhere after school. Where is it you want to go?

SUZY

We were going to go around the Old Courthouse Square to get clues to the past.

SCOTT

That's great. That's where I've got to be.

SUZY

See you after school then. Don't be late.

Suzy and Amy head off.

In the Old Courthouse Square, the camera shows a close up of the Clock Tower, which still reads 10:04. The camera pans out and sweeps across the square, which has a small lake in the middle. The setting very similar to what it was in the 2015 envisioned in Back to the Future part II, but without flying cars buzzing around. Scott, Eric, Amy and Suzy walk along the side of the lake in the square.

SUZY

As soon as we get this assignment over the better.

ERIC

Hey guys, I've got to get off. Things to do.

SCOTT

Where are you going? We've only just got here. You said you'd come and check out the Café 80s to see if anything happens.

SUZY

See if what happens?

ERIC

Scotty here reckons his dad travelled into the future thirty years ago to today. He wants to go meet up with him.

SCOTT

Eric!

SUZY

What's this all about? You having a joke aren't you?

ERIC Bring me a hoverboard to school tomorrow Scott. See ya later lovebirds, I've gotta go home.

Eric and Suzy frown at the 'lovebirds' joke as Eric leaves.

ERIC

Take no notice of him. He's got a few short circuits in his head.

Amy gets a message on her cell phone.

AMY

Sorry guys, I've gotta shoot too. Mom wants me home.

SUZY

You're not going to leave me are you?

AMY

You two will be okay. Just watch he doesn't get a lighter out. You don't want your hair to catch fire again.

SUZY

Very funny.

AMY

See you later on.

Amy leaves.

SCOTT

Looks like it's just us now. Don't worry, I don't bite.

Suzy pulls a face. The two of them carry on around the lake. An old guy, Terry, is shaking a tin, as Scott and Suzy pass by.

TERRY

Save the Clock Tower!

SCOTT

No thanks.

TERRY

Come on kid, it's an important historical landmark. Lightning struck that thing sixty years ago.

SCOTT

I know. My Dad was there... twice!

Terry looks confused at Scott.

TERRY

Eh?

Suzy takes a flyer as she and Scott walk away from Terry.

SUZY

Your dad was there twice? Sixty years ago. What are you on about? Suzy jokes with Scott.

SUZY

Is your dad a time traveller? He could come in useful with this assignment.

SCOTT

I'm going into the Café 80s. What are you doing?

SUZY

I'm coming with you. I want you to look over the notes I made about what old buildings are left in the Courthouse Square.

SCOTT

Yeah, whatever.

Scott and Suzy walk away and into the Café 80s.

In the Café 80s, 'Into the Groove' by Madonna is playing. The layout of the Café is similar to how it was in Back to the Future part II. The walls are decorated in 1980s memorabilia and on the tables are TV screens playing shows of the 1980s. Biff Tannen aged 78, is seen in the background. He doesn't see Scott and Suzy. Two 'cyclists' are inside pedalling on exercise bikes. The computer monitors are serving as they were in Back to the Future part

II.

SCOTT

Two Pepsi Perfects please.

Two drinks pop up out of the counter, Scott pays for them, collects them, hands one to Suzy and they sit down at the table across the way. Scott fiddles with his iPhone.

SUZY

I hate those monitors; I'd rather speak to a real person. Why did they have to choose Hill Valley to pilot the idea? It'll never catch on.

The music switches to 'Beat It' by Michael Jackson.

SCOTT

I quite like them; it'll put Hill Valley onto the map, the town of tomorrow!

SUZY

Yeah, but they put people out of work. Imagine if all the shops had them, how many people in this town would be unemployed?

In the background Marty enters and goes up to the counter. Scott and Suzy don't notice him.

SCOTT

It would encourage people to do something more with their lives than just work in shops.

Eric's Grandfather used to be the cleaner in this place sixty years ago and went on to become the mayor of Hill Valley. That's before his dad did as well.

SUZY

There aren't enough other jobs out there for all the shop workers in Hill Valley. Anyway, how do you know some old mayor used to be a cleaner here sixty years ago? Let me guess; the amazing time travel story told you. How long are we gonna be stuck in here for?

SCOTT

Quit moaning will you, I did just buy you that Pepsi.

SUZY

Can we go over to the Lone Pine Mall after we've been here? There's a great outfit that I've had my eye on in the sales there. You could always get it for me for Christmas. It's not far off you know. It's the end of October now.

SCOTT

Do you think I'm made of money?

SUZY

Your Dad's Mr. Rich Rock star.

SCOTT

I don't see much of it. He reckons not letting me have stuff will stop me being spoilt.

Scott shows Suzy his iPhone.

SCOTT

Look, I've still only got the iPhone 5, it's way old.

Suzy interrupts.

SUZY

Hey, isn't that your brother over there. That old man with the cane is talking to him. He can't have seen you, shall I call him over?

Scott swings round to see his brother. He realizes that it's his dad and goes pale.

SCOTT

NO! Leave it.

SUZY

Why? Have you two fallen out? Uh oh, looks like trouble, Griff Tannen's just pulled up outside.

Scott is still in shock. He whispers to Suzy.

SCOTT

He's my d... my d... my dad!

SUZY

Don't be stupid, it's your brother.

SCOTT

I'm not messing. You know what Eric was saying about my dad being a time traveller. I think it's actually true. That kid over there is not my brother Marty McFly Junior; it's my dad, Marty McFly Senior.

Suzy doesn't believe Scott.

SUZY

Get out of town.

Griff Tannen enters the café.

GRIFF

Hey Gramps, I told you two coats of wax on my car, not just one!

Biff gets up. Scott watches gob smacked. Suzy looks puzzled.

BIFF

Hey, hey, I just put the 2nd coat on last week.

GRIFF

Yeah, with your eyes closed?

YOUNG MARTY SENIOR

Are you two related?

Biff raps Young Marty on the head with his cane.

BIFF

Hello, hello, anybody home?

Marty tries to avoid Biff's cane.

BIFF

What'd you think; Griff just calls me grandpa for his health?

Young Marty looks worried.

YOUNG MARTY SENIOR

He's Griff?

GRIFF

Gramps, what the hell am I paying you for?

BIFF

Hey kid, say hello to your grandma for me.

Griff pulls Biff out of the cafe.

GRIFF

Get out of there Gramps!

BIFF

Hey, take it easy!

Griff comes back in.

GRIFF

Hey McFly, don't go anywhere, you're next!

Griff leaves. Marty looks around the Cafe again and sees Wild Gunman, a video game. Two boys are next to it.

VIDEO GAME BOY

This is a video game! I got it working!

VIDEO GAME BOY 2

My dad taught me about these.

YOUNG MARTY SENIOR

It is Wild Gunman.

Marty heads over to the game away from where Scott and Suzy are seated.

SCOTT

That is not my brother, didn't you hear what he was saying. He didn't know who Griff was.

Suzy starts to believe.

SUZY

There's got to be a reasonable explanation

Marty Junior enters the Café 80s and head to the counter.

MARTY JUNIOR

Pepsi perfect.

Scott's eyes pop out of his head.

SCOTT

Explain why there's now two Martys in here then.

Suzy's jaw drops.

SUZY

Like... You weren't kidding.

SCOTT

Come on Suzy we've gotta get out of here.

Griff enters the Cafe. This time he's accompanied by his gang, Data, Spike and Whitey. Scott and Suzy duck down behind the seats.

GRIFF

Hey McFly, I thought I told you to stay in here.

MARTY JUNIOR

Griff, guys.

Marty Junior pushes his jacket up his arm.

MARTY JUNIOR

How's it going?

GRIFF McFly!

MARTY JUNIOR

Yeah?

GRIFF McFly!

MARTY JUNIOR

What?

GRIFF

Your shoe's unvelced.

Marty Junior looks. Griff punches him and the gang laugh. Marty Junior falls onto the counter. Scott and Suzy grab their schoolbags, sneak past and out of the door quickly and out to the street Old Courthouse Square.

Scott starts to ramble.

SCOTT

Now do you believe it? Jesus Christ, there really is a time machine. The DeLorean. Where is it?

Scott frantically searches through the story on his iPhone. Suzy is still speechless.

SCOTT

I know where it is, come on.

SUZY

What? What are you going to do?

SCOTT

The DeLorean. I'm going to check it out.

SUZY

What the hell is a DeLorean?

Scott rushes from the Café 80s, closely followed by Suzy. Scott points towards the side street where the DeLorean should be parked.

SCOTT

A DeLorean? It's a car. It's what the time machine was made out of. It's parked in the side street over there.

Suzy looks bemused.

SCOTT

We have to go check this out. I've waited months for this day.

SUZY

Time travel is impossible, it can't be true.

SCOTT

It's got to be, unless my brother's cloned himself. This is mad. Dad looked the spitting image of him. I wonder what he was like back then.

Suzy starts to believe in Scott's theory.

SUZY

Don't tell me you actually want to go time travelling. That is if it's real. I mean you can't possibly...

Scott flicks through his iPhone to check something out.

SCOTT

October 27 1985.

Suzy spies across the street a small girl alone playing on a pink scooter by the lake in the square. She sees something is odd. The girl keeps looking at the café and scooting up and down. Suzy looks closer at the scooter.

SUZY

Scott, check that out, that scooter the little girl is on hasn't got any wheels... It's hovering!

Scott is once more shocked.

SCOTT

A hoverboard! Where the hell did that come from? This is 2015, not... 2115!

A commotion sounds in the café and young Marty Senior comes bursting out. He spies the little girl on the scooter and runs over to her.

YOUNG MARTY SENIOR

Hey, hey, hey, hey, hey! Hey, hey, hey, hey! Stop, little girl, little girl, stop! Look!

Marty lifts the girl off her scooter.

GIRL

Hey!

Marty breaks off the handlebars and looks in amazement.

YOUNG MARTY SENIOR

I need to borrow your... It's not a scooter - it's a...Hoverboard?

Griff's gang leave the Café 80s.

DATA

Where is he?

Marty Senior gives the handlebars to the girl.

YOUNG MARTY SENIOR

Here.

Whitey points at Young Marty.

WHITEY

There!

Young Marty puts the hoverboard down, and it hovers. He looks at it, and then jumps on, hovering past the Cafe 80s.

WHITEY

He's on a skateboard... that hovers!

Scott drags Suzy away from the scene that's unfolding in the square. As Marty Senior hovers away, and Griff's gang gives chase, Scott and Suzy hurry down the street towards the side street with the DeLorean in. On the corner of it they see a white haired man in strange looking clothes watching the hoverboard chase through a pair of binoculars.

Scott whispers to himself.

SCOTT

The Doc! He's the one who invented the time machine.

The two run down the side street without Doc Brown noticing them. He's too engrossed in what Mart Senior is up to. They find the DeLorean parked up next to some trash.

SCOTT

Look, that's the DeLorean. That baby is a time machine!

SUZY

Like... you weren't kidding. That Doc... He built a time machine... Out of a car? Hang on, look out, there's someone asleep on the trash heap. Look.

Asleep on the trash is 17-year-old Jennifer.

SCOTT

It's my mom! Look at her, she's so young!

Suzy looks amazed at the sleeping teenage Jennifer wearing 1985 clothing.

SUZY

That's mad! Why is she asleep?

SCOTT

Apparently she was asking too many questions about the future. Doc put her under an anaesthetic.

Scott tries the door of the DeLorean.

SCOTT

The DeLorean, it's unlocked! What a stroke of luck. After all these months of researching online to work out how to break into 1980s cars and they left it unlocked!

Suzy acts nervously.

SUZY

You've been planning to do this? I can't go time travelling. I mean we can't go... I've got to go home for my dinner.

SCOTT

We'll be back to get you home for your dinner. Think about it, no time here will pass whatsoever, if we bring the car back to this exact moment. I only want to go for a little trip to try it out.

SUZY

Isn't it dangerous? I've seen stuff on TV about it.

SCOTT

I'll take you on a small sightseeing trip and bring you straight home. I promise.

Scott looks at the Mr. Fusion fuel tank on top of the DeLorean.

SCOTT

Cool. Mr. Fusion! All I need to do is pop a bit of trash in here.

SUZY

I'm not sure. Where do you want to go?

SCOTT (throwing his school backpack into the car and climbing in himself) Go? Right here in Hill Valley.

SUZY

Alright then, when? You know what I meant.

SCOTT

Damn, no keys, only one thing for it.

Scott messes around with the ignition pulling wires out and connecting them. The DeLorean roars into life.

SCOTT

Hop in, were going back to good ol' 1985!

Suzy looks round nervously. Too curious to walk away, she climbs into the car and closes the door.

They both sit inside the DeLorean looking at the controls.

SUZY

I hope you know what you're doing.

SCOTT

Relax; my Dad had all sorts of diagrams and sketches on the computer. See this at the back? This is called the flux capacitor, which is what makes time travel possible. These readouts at the front tell you where you are, where you're going and where you've been. You just tap the date and time in here and off we go.

Scott taps in October 27 1985 9:00am.

The car's wheels turn in, as it's been hover-converted. The car then lurches into the air.

SUZY

How do you know how to drive this thing? You're only fifteen.

SCOTT

Dad's been taking me driving lessons off road since I was twelve, and the flying, well, that's no different to the video games I've got at home. Hey Suzy check out the milometer, when this baby hits 88 miles-per-hour, you're gonna see some serious stuff!

Scott lifts the car up into the air. It's apparent he's a bit of a novice, but he manages to avoid colliding with any of the buildings. When they reach a clear bit of air space, Scott presses down on the accelerator.

The miles-per-hour creep up on the dial to fifty, then to sixty, seventy and eighty. The car soars above Hill Valley. Bright lights start flashing outside the car and when it hits eighty-eight miles per hour, three sonic booms are heard. Suzy lets out a small scream and then silences.
