Theorizing that one could time travel within his own lifetime, Dr. Sam Beckett stepped into the quantum leap accelerator and vanished. He awoke to find himself trapped in the past, facing mirror images that were not his own, and driven by an unknown force to change history for the better. His only guide on this journey is Al, an observer from his own time who appears in the form of a hologram that only Sam can see and hear. And so, Dr. Beckett finds himself leaping from life to life, striving to put right what once went wrong, and hoping each time that his next leap will be the leap home.

Disco Inferno

• Kinda looks like Sam has leaped onto the set of Saturday Night Fever.
• But he’s really not feeling the disco music or the platform shoes he’s wearing.
• Out of nowhere, someone pulls out a shotgun and shoots Sam, knocking him backwards through a window.
• April 1, 1976
• Sam lands on a safety pad…
• He’s a stunt performer from a family of stunt performers.
• Sam’s father must be the stunt coordinator and his sons are his assistants.
• The stunt coordinator accuses the director of running an unsafe set when someone moved the safety pad and quits, taking his sons with him.
• Sam has leapt into Chad Stone who appears to get a lot of interest from the ladies on set.
• A woman named Tracy gives him a mood ring, which turns black as soon as she slides it on his finger.
• Sam sneaks away and notices Al dancing.
• Across the set, the younger brother is talking to a girl who is actually more interested in him than in Chad, which is something he’s not used to.
• Al tells Sam he’s on the set of the low-budget disaster flick, Disco Inferno, in Burbank.
• Unfortunately, Ziggy crashed a couple days ago, so there’s not a lot of information.
• But before the crash, Ziggy did reveal that in the next two days, Chris, the younger brother, is going to die.
• Al telling Sam to play big brother for the next two days reminds Sam that he had a big brother named Tom.
• He doesn’t remember anything about Tom and asks Al where he is… how he is…
• But Al reminds Sam of the rules and can’t reveal that info.
• Later, Chris argues with his dad about quitting the movie and is desperate for a chance to do his first big stunt.
• Tomorrow, Chad is supposed to do a fall on the set of Earthquake and Chris asks if he can take it.
• Sam just says no, unsure of when or how Chris could get killed.
• At home, Chris is in his room playing guitar and he’s really good.
• Sam tries to push him toward music as a potential career instead of stunt work.
• Then Chris gets excited when Shannon, the girl he met on set today, shows up at their apartment.
• The three of them watch SNL together until Sam sees Al out on the balcony and excuses himself.
• Sam asks Al how he’s killed… and Al asks who…
• Al may be thinking that Sam is remembering that Tom is dead, but Sam is really talking about Chris.
• But they still don’t have an answer to that since Ziggy is spitting out info in Japanese at the moment.
• The next day, on the set of Earthquake, Sam is terrified to perform his stunt, which is a fall from several stories up.
• He’s almost saved by Lorne Greene, but loses his grip and performs the fall perfectly.
• Chris is still pissed that Sam wouldn’t give him the stunt, but Sam is still trying to convince him that music is the path he should go down.
• Sam gets in touch with Tracy, who works with a record label, and convinces her to give Chris a shot at performing live.
• Their dad is supposed to show up to watch him perform, but he’s in the bar getting drunk.
• Sam confronts him about why he treats Chris so badly…
• He admits it’s because Chris was born weak and after he split with their mom, she raised him to be weak.
• In their dad’s eyes, he needs to toughen him up in the stunt industry.
• Chris begins to perform and his dad stumbles in scowling.
• He’s there long enough for Chris to see him walk off in disgust.
• Once he finishes singing, Chris heads to the bar seeking dad’s approval.
• Of course he tells him he’s wasting his time.
• His dad starts egging him on, leading to Chris punching him in the face.
• Then Chris calls the Disco Inferno director and confirms he’ll be there for the fire stunt tomorrow.
• Al shows up when Sam is alone at home.
• Sam says he’s having a hard time with this leap, trying to give Chris good advice like a big brother would, but he’s just not listening.
• Suddenly it hits Sam… He didn’t figure out that Tom was trying to help him all those years until it was too late because Tom died in Vietnam.
• The next morning, Sam goes to their dad since Chris never came home last night.
• They talk for a while and figure out that Chris is desperate to prove he can be a stunt performer with the unsafe fire stunt on Disco Inferno.
• Sure enough, it’s not safe and an uncontrolled fire breaks out on set.
• Sam gets there in time to save Chris from being killed.
• Some time later, after Chris has clearly been released from the hospital, Chris and Shannon watch a basketball game with his dad.
• Al visits Sam in the kitchen and he wants to know why he hasn’t leapt yet.
• Al knows he shouldn’t do it, but he shows Sam a picture of him with Tom.
• Back in the living room, the discussion turns to Chris’ music again.
• As a live report of President Ford getting off Air Force One comes on, Sam bets that Ford will fall at the bottom of the stairs.
• If he does, their dad has to get behind Chris’ music career.
• If not… Sam will get behind Chris as a stunt performer.
• Sure enough, President Ford fell again…
• Then Sam leaps into a sailor stepping off a bus.
• Oh boy.
