Radio Announcer: (v.o) Oklahoma ripped Ohio State 52-0.
Biff puts the almanac on the seat next to him. Marty spots his chance!
Radio Announcer: (v.o) West Virginia lost to Pittsburgh 26-7.
Marty quietly opens the car door.
Radio Announcer: (v.o) Maryland defeated Clemson 25-12. Repeating tonight's earlier weather bulletin, a severe thunderstorm is heading for Hill Valley.
Biff looks around and sees Marty. Marty tries to grab the almanac. Biff turns to face the front again, before suddenly realising who it is and turning round again. He grabs the book, as does Marty, and they are having a tug of war over it.
Biff: Don't even... give me that book! Let it go!
Biff kicks Marty, and the almanac flies in the air, landing on Biff's windscreen. Marty is still holding onto the car, and Biff spots some barriers ahead.
Biff: Let go of the car!
He drives around in circles, but both Marty and the almanac stay attached to it. Biff drives forward, passing a sign - "Tunnel Ahead". Biff drives towards the tunnel edge, hoping to force Marty off. Marty gets to the back of the car, and the side of the car id dented by the tunnel. Biff looks around - no Marty (he doesn't know Marty is hiding behind the back of the car).
Biff: That'll teach him.
Biff tries to grab the almanac, but as he does so he looks in the mirror and spots Marty. Marty makes his way towards Biff. Biff elbows and punches Marty, and then spots a truck approaching in the other direction. Biff drives past, and Marty uses the hoverboard to escape - and then grabs the almanac. Letting go of Biff's car, he stops in the middle of the tunnel. Biff gets to the edge of the tunnel and turns around. Marty looks at the other end - it's some distance away! Marty puts the almanac inside his jacket and sets off. Biff revs up his car, puts his foot on the pedal and sets off after Marty.
Marty: Argh!
Biff is getting closer, He pus the pedal down again and laughs evilly. Marty is almost at the end of the tunnel but Biff is almost on him.
Marty: Woah!
He's at the end of the tunnel, when the flag pennant trails down and Marty grabs onto it. Doc, in the DeLorean, pulls Marty up to safety. Biff looks up in amazement.
Marty: Go Doc!
Doc: Hold on Marty!
Cut to Biff's point of view. He sees a flying futuristic car and a kid on a hovering board. He's so mesmerised he doesn't see the truck in front of him until it's too late.
Biff: Shit!
He crashes into it, and finds it's a manure truck! Cut to Marty.
Marty: Ha, ha, ha, yeah!
Cut to Biff.
Biff: Manure! I hate manure!
Cut to the DeLorean. It flies to the billboard, and Marty lets go of the flag ribbon. He takes his foot off the hoverboard and speaks to Doc over the walkie-talkies. Note: the lightning storm is starting.
Marty: (w.t) Doc, is everything all right, over?
Doc: (v.o) 10-4 Marty, but it's very miserable flying weather.
Cut to Doc.
Doc: (w.t, continued) I'm going to have to turn and make a landing from this direction. I'll have to circle round and make a long approach from the south. Have you got the book?
Cut to Marty.
Marty: (w.t) In my hands Doc, I got it in my hands!
Doc: (v.o) Burn it!
Marty: (w.t) Check!
Marty kicks up the hoverboard and spots an old bucket. He puts the almanac in the bucket and takes out the matchbox he took from Biff's Pleasure Paradise. He lights a match and starts to burn the book. He then looks at the matchbox. The words are starting to change! Eventually they change from "Biff's Pleasure Paradise" to "Biff Auto Dealing". Marty then pulls out the newspaper. The headline changes from "George McFly Murdered" to "George McFly Honored".
Marty: (w.t) Doc, Doc, the newspaper changed! Now my father's alive! That means everything's back to normal, right?
Cut to Doc. He pulls out the newspaper he had. The headlines change from "Emmett Brown Committed" to "Emmett Brown Commended", "Nixon To Seek Fifth Term" to "Reagan To Seek Second Term" and "Biffco Builds New Dioxin Plant" to "Mayor Wilson Vetoes Zoning Bill".
Doc: (To himself) Mission accomplished.
Cut to Marty.
Marty: (w.t) That means Jennifer's OK and Einie's OK, right?
Cut to Doc.
Doc: (w.t) That's right Marty! It's the ripple effect, the future is back. Now let's go home!
Cut to Marty.
Marty: (w.t) Right Doc, let's get our asses back to the future...
Lightning strikes, bringing down a tree.
Marty: (w.t) Doc, Doc, are you OK?
Cut to Doc.
Doc: (w.t) That was a close one Marty, I almost bought the farm!
Cut to Marty.
Marty: (w.t) Be careful, you don't want to get struck by lightning-
