The five of them get inside the Delorean and Doc puts it into gear to fly. Marty is sitting in the passenger seat with Jennifer sitting in his lap. Einstein is put behind Ally, who was sitting between Doc, Marty, and Jennifer.
As they flew through the air to the skyway, Doc pressed the buttons on the time panel to the correct date. He pressed October 26th 1985, 9 PM. "Marty, Ally, Einie, brace yourselves for time dispersal," Doc warned them, holding onto the steering wheel tightly.
Marty holds Jennifer with one arm while holding onto Ally's hand with the other. Doc speeds up the Delorean to 88 mph, The flux capacitor discharges a burst of intense white light, they hear three sonic booms before the skyway disappears before their eyes.
They all looked around, feeling uneasy from just how quiet it really was. There was nothing but the white sky with lights below them.
"Did we make it?" Marty asked. Ally looked out of the windows with wide eyes and asked, "Are we back?" Suddenly, their question was answered by a thunderous roar, almost wiping them out. Marty and Ally screamed in shock for a moment before calming down again. "Yeah, we're back," Doc nodded.
Doc flies the Delorean to a 1985 residential street. He drops the wheels and lands onto the road. He drives for a couple of minutes before pulling up in front of Jennifer's house.
They get out and carry Jennifer on the porch. "Put her in the swing! I'll take both of you home. Marty, you can take your truck and wake her up. When she sees she's in her own house and it's dark, both you and Ally should convince her that it was a dream," Doc says, running to the Delorean.
"You're the doc, Doc," Marty commented. "How long will she be out for?" Ally asked. "I'm not sure since she received quite a shock. Could be either a few minutes or a couple of hours. You'd better bring some smelling salts with you two," Doc answered.
Ally looks at the house and notices that something was off with Jennifer's house. "Um… Marty, call me crazy but… I don't remember bars being on the windows," Ally said, seeing what looks to be like jail bars screwed into the windows.
Marty saw them too and was just as confused. "Yeah, not to mention, something doesn't smell too good," he replied, sniffing the air. Doc caught wind of the smell and made a face. "Must be a fire somewhere. C'mon, let's get going," Doc said. The three and the dog all jump into the Delorean and drive away from Jennifer's house.
Doc drives the siblings back to Lyon Estates, which looked different. The entrance was covered in graffiti, the street was strewn with trash. A pack of stray dogs runs by just as the Delorean turns into the street. Most of the houses were empty, boarded up, or are for sale. Something was definitely off about this place.
Doc pulls up in front of their house and the siblings step out of the Delorean. "If you two need me, I'll be in my lab, dismantling this thing," Doc tells them before driving off towards his house.
"C'mon, I think we had enough time traveling for one day," Marty tells his sister, to which she agrees. They jog to the side gate. "Um… why is this locked?" Ally asked in confusion, seeing a heavy-duty padlock on the gate door.
"This isn't usually locked though," Marty commented, also finding that very weird. He then pulls up a small trash can that they could use to climb over. "C'mon, let's get inside," Marty says, climbing over the gate. "Right behind you," Ally says, following him.
He helps her down and the two make their way to the window. To their luck, it was still open partly so they had free access into the house. Marty crawls in first before Ally, only to be greeted with a loud scream.
The scream belonged to a fifteen-year-old black girl and she scooted back to the headboard of her bed, screaming her head off for her parents. "Whoa! Who are you?! Why're you in our room?!" Marty cried in shock.
"What the hell is-?" Ally started, seeing that their room now belonged to this girl. "MOM! DAD, HELP! RAPE! MOM!" the girl screamed at the top of her lungs.
Suddenly, the door bursts open and a light turns on. "Freeze, suckers!" the girl's father comes rushing in with a baseball bat. Behind him was a small boy about 12 years old. Ally and Marty jumped off of the bed in shock.
"Whoa! Hey, we don't want any trouble!" Marty cried, holding his hands up. "Well, both of you got trouble now, you pieces of trash!" the man shouted, swinging the bat at them. They duck out of the way, making the dad hit some of his daughter's possessions.
"What're you two doing in here with my daughter?!" he shouted, raising the bat again. "Hey, we're just in the wrong house! We didn't know!" Ally shouted, holding up her hands. "Whoop them, dad! She's lying!" the little boy shouted.
"We just made a mistake!" Marty stammered in panic. "Damn right, you two made a mistake!" the dad shouted, taking another swing at the siblings again. Marty grabs Ally's hand and the two bolted out of the front door, the family following behind them.
"Yeah, keep running, you suckers! Tell that white trash reality company that I ain't seeing, you hear?! We ain't gonna be terrorized!" the father shouted as the two kept sprinting as fast as they could.
They kept running until they reached the next street. There was loud gunfire in the distance. A car drives by, full of screaming kids as they throw their beer bottles out onto the street.
Both were confused now. Things weren't like this the last time they were here. On the ground, they were horrified to see two taped outlines of two murder victims, one who was shot in the abdomen, and the other who was shot in the head.
They run down another street as two cop cars drive passed them in the background. "Marty, what the hell's going on here? What's happened to this place?" Ally asked, completely stunned by how much everything's changed.
Marty looked around, panting heavily, scratching his head in confusion. "I don't know, Ally. But… this can't be the right year," Marty said, walking over to a house with a newspaper on it. Ally follows him and saw the paper too.
Marty sits down on the porch steps and picked up the paper, reading it closely. "Oh, no, Ally look," Marty said, turning the paper so she could read it. It read, 'October 26, 1985,'
"What? This can't be," Ally gasped, taken aback that they were really in 1985, but not their 1985. Suddenly, someone behind them cocked a shotgun behind them, causing both of them to freeze. "Drop it!" the owner demanded.
Without turning around, Marty throws the paper onto the ground a few feet away from them. Their eyes widened in fear as they both looked over their shoulders. "So you two are the sons of bitches that's been stealing my papers," Mr. Strickland hissed, aiming his loaded shotgun at the siblings.
Their vice-principal looked so much different than before, looking meaner than before. He had a large, ugly knife scar across his face. He was wearing a flak jacket with ammo in it over his bathrobe.
"Mr. Strickland!" Marty exclaimed. The two siblings slowly stand up. "Don't you recognize us? Marty and Ally McFly?" Marty continued, fearing for his life.
"Who?!" Strickland shouted, aiming the shotgun at Marty's chest, finger on the trigger. Ally freaked out when she saw this, holding her hands up. "Marty McFly and Ally McFly! Don't you know us from school, sir?!" she shouted, freaking out.
"I've never seen you two before in my life, but you two look like slackers!" Strickland spat back. "Yeah, that's right! We are slackers! You gave us detention last week, don't you remember?" Marty said, hoping to jog his memory.
"Last week at school? It burnt down six years ago! Now, you've got exactly three seconds to get the hell off of my porch with your nuts intact!" Strickland shouted, aiming the shotgun at Ally, "Don't think I won't shoot you, girl!"
Marty stands in front of his sister to protect her from the shotgun blast. "One!" Strickland started. Marty's eyes got huge as the gun was trained at his crotch. "AH! Please, we just want to know what the hell's going on here!?" Marty cried.
"Two!" Strickland continued. "Ah! Please, don't shoot!" Ally cried out, her heart jumping out of her chest. Then, a car speeds by the house, and three teens stick their heads out with their guns. "Hey, Strickland!" one yells.
Strickland dives inside his house. Marty quickly grabs his sister and they duck behind the porch with his arms around her. They heard the rapid gunfire coming from the teen's guns. When they were finished, Marty and Ally rise up quickly in a panic.
They run off the porch and onto the sidewalk just as Strickland came running out of his house. He fires his shotgun at the gun-weilding teens. "Eat lead, slackers!" he shouts, running after them.
Marty and Ally sprint away as fast as they could. Until they reached the town square. First thing they see was the Hill Valley sign graffitied to say Hell Valley, which was broken and on the ground. There were also bullet holes in it.
As they walked around in shock, they saw that Hill Valley wasn't anything like it used to be. There were strip bars, adult book stores, pawnshops, bail bondsmen, and porno theaters. The whole square was riddled with fire, bikers, and even a damn tank.
What's most shocking of all of this, was that the courthouse had been turned into a gigantic Las Vegas-style high rise hotel complex called 'Biff Tannen's Pleasure Paradise. Hotel, Resort, Casino, Girls,'
The front of it was of flashing lights that included an animated portrait of Biff lighting a cigar with a $100 bill. There was so much pollution coming from the industrial smokestacks that were in the distance.
Both siblings were dumbfounded at how disturbing Hill Valley looked now. They make their way up to the courthouse, only to see two bouncers, who were Match and 3-D, throwing a young man out of the front doors.
"Don't ever come beggin' for drinks in here again! Friggin' lush!" 3-D shouted. The drunk man gets to his feet, stumbling around.
"Hey, can't you guys take a joke?" he spat, slurring his words. Ally squints her eyes to look at the young man and realized that this drunk was their older brother, David. "Marty, it's David!" she cried.
Marty reacts to what Ally said, gasping at the realization. David pulls out a pint bottle from his ragged coat, gulping down the last drop before throwing it at the casino. They walk up to him in disbelief.
"David?! Is that you?!" Ally shouted, getting David's attention. He looks at them and smiles drunkenly at them. "Marty! Ally! Hey, what's happenin'? You two are looking kinda ragged there- what'd you two sleep in your clothes again?" he laughed, looking plastered.
"Dave, my God, what happened to you?! What happened to this town?!" Marty exclaimed, eyeing his brother up and down. "Can you tell us what the hell's going on here?" Ally asked, looking around again.
"Oh, this is the Biker's Convention! So, when'd you get back?" Dave answers, waving his hands around as if he was presenting something. Both Marty and Ally were confused at what their brother said. "Back from where? What're you talking about?" Marty asked.
"Well, if you don't know, then how do you expect me to tell you two?" Dave said, laughing loudly. He suggested that they'd go catch a drink, but they couldn't because they were underage.
"David, we gotta find mom and dad! Do you know where they're at?" Ally asks, feeling a headache coming on. David narrowed his eyes on his little sister. "Dad? You and Marty gotta find dad? That's sick, Ally! And since when are you two on speaking terms with mom again?" David spat, walking away from them.
"Speaking terms? Look, do you know where mom is or not?" Marty asks. "Same place as usual! In there!" David replied, pointing at the hotel behind them. Both siblings stare up at the hotel in confusion.
"What? Why would she be in there?" Ally asked, looking at her brother. "I don't know, Ally, but we gotta find out," Marty replied, turning around. They both see that David had left them, entering a bar. They didn't go after him.
They walk up to the entrance and see a tv playing a video. "Ladies and gentleman, welcome to the Biff Tannen Museum, dedicated to Hill Valley's number one citizen, and America's greatest living folk hero, the one, the only, Biff Tannen. Of course, we all heard the legend. But who is this man? Inside, you will learn how Biff Tannen became one of the richest and most powerful men in America,"
The screen changes to show Biff driving an expensive car from an expensive house. The narrator goes on to explain how Biff became rich overnight. It talked about his great-grandfather, Buford 'Mad Dog' Tannen, the fastest gunman in the west.
Biff had become insanely rich because of him winning bets at horse races. He opened a company called 'Biffco'. He made gambling legal in 1978 and had turned the courthouse into a casino-hotel.
The next piece of info almost made the siblings throw up in shock. "Meet the woman who shared in his passion as he searched for true love…" the narrator continued, and a picture of their mother popped up on the screen.
"He relived his happiest moment, as in 1973, he had gone on to marry his high school sweetheart, Lorraine Baines-Mcfly," the narrator finished. The screen showed their mother getting dragged out of the church by Biff. He then starts kissing her on the mouth roughly.
"OH MY GOD! NO!" Ally screamed, backing away from the stairs, eyes wide. "NO!" Marty shouted, both enraged and in shock. Suddenly, they were grabbed by Biff's boys as they backed away in horror.
"Let us go!" Marty shouted. "Hold on now, you two are coming with us," Match said, holding onto Ally tightly around her shoulders.
"Listen, we can do this the easy way or the hard way," Pinhead says. However, they kept fighting against their grips. But both siblings get hit over the head with a blunt object, knocking them out instantly.
