Plot
On November 12, 1955, Marty
McFly discovers that his friend, Dr. Emmett Brown, is now trapped in
1885. Marty and Doc's 1955 self use the information in Doc's 1885 letter
to locate and repair the DeLorean. Marty spots a tombstone with Doc's
name, dated six days after the letter. Learning that Doc was killed by
Biff Tannen's great-grandfather, Buford "Mad Dog" Tannen, Marty travels
back to 1885 to save Doc.
Marty arrives on September 2, 1885, in the middle of a United States
Cavalry pursuit of Indians. When the fuel line is torn, Marty hides the
car in a cave and walks to Hill Valley. He meets his Irish-born
great-great-grandparents, Seamus and Maggie McFly, and runs afoul of
Buford and his gang. Buford tries to hang Marty, but Doc saves him. Doc
agrees to leave 1885, but because commercial gasoline is not yet
available, the DeLorean cannot reach 88 miles per hour under its own
power.
Doc devises a plan to use a locomotive to push the DeLorean up to the
required speed. While he and Marty explore a rail spur they intend to
use, they spot an out-of-control horse-drawn wagon. Doc saves the
passenger, Clara Clayton, and the two fall in love. Marty thwarts
Buford's attempt to kill Doc at a town festival, whereupon Buford
challenges Marty to a showdown in two days. Doc's name disappears from
the photograph of his tombstone, but the date remains unchanged; Doc
warns Marty that he might be the one killed by Buford.
The night before their departure, Marty and Doc place the DeLorean onto
the rail spur. At Clara's house, Doc tells her he is from the future,
but she believes it is an excuse to end their relationship and angrily
dismisses him. Distraught, Doc returns to the town saloon for a binge,
but Marty rides to the saloon and convinces Doc to leave with him. Doc
drinks a single shot of whiskey and passes out instantly. Buford arrives
early and calls out Marty, but Marty refuses to duel. Doc revives after
drinking the bartender's special "Wake-Up Juice" and tries fleeing with
Marty, but Buford's gang captures Doc, forcing Marty to duel. During a
fistfight, Buford destroys the tombstone, is knocked unconscious into a
wagon full of manure, and is then arrested for an earlier robbery. Marty
and Doc depart to steal the locomotive.
As Clara is leaving on the train, she overhears a salesman discussing
how heartbroken Doc was at the saloon. Clara applies the emergency brake
and runs back to town. She discovers Doc's model of the time machine
and rides after him. Having stolen the train at gunpoint, Doc and Marty
begin pushing the DeLorean along the spur line, attempting to get it up
to 88 miles per hour. Clara boards the locomotive while Doc climbs
towards the DeLorean. Doc encourages Clara to join him. As she climbs to
Doc, Clara falls and hangs by her dress. Marty passes his 2015-era
hoverboard to Doc so he can save Clara. They coast away from the train
as the DeLorean returns to 1985, while the locomotive falls off the
unfinished bridge.
Marty arrives on October 27, 1985, escaping the powerless DeLorean
before it is destroyed by an oncoming freight train. He discovers that
everything has returned to the improved timeline and finds Jennifer
sleeping on her front porch. He uses the lessons he learned in 1885 to
avoid being goaded into a street race with Douglas J. Needles, avoiding a
possible automobile accident. Remembering that this accident would have
sent Marty's life spiraling downward by 2015, Jennifer opens a fax
message she kept from 2015 and watches as its text regarding Marty's
firing disappears.
Marty takes Jennifer to the time machine wreckage. A locomotive equipped
with a flux capacitor appears, manned by Doc, Clara, and their two
children Jules and Verne. Doc gives Marty a photo of the two of them by
the clockworks at the 1885 festival. Jennifer asks about the fax, and
Doc tells them it means that the future has not been written yet. Doc’s
train converts into an aerial craft and disappears into an unknown time.
