On November 12, 1955, moments after witnessing Dr. Emmett Brown disappear in his DeLorean, Marty has learned that he was transported to 1885.[N 1] Marty and the 1955 Doc have received Doc’s 1885 letter and use its information to find and repair the DeLorean so Marty can return to 1985. Although Doc’s letter expresses his desire to remain in the Old West, Marty finds and photographs a tombstone with Doc’s name, dated six days after the letter. The inscription states that Doc was shot in the back by Biff Tannen‘s great-grandfather, Buford “Mad Dog” Tannen, over a matter of $80.
Marty travels to September 2, 1885 to save Doc, arriving amidst a cavalry pursuit of Native Americans. When the DeLorean’s fuel line is torn, Marty hides the car in a cave only to be chased by a bear and knocked out. Found by his Irish-born great-great-grandparents Seamus and Maggie McFly, he spends the night at their farm. The next morning, he walks to Hill Valley and runs afoul of Buford and his gang. Buford attempts to lynch Marty, but Doc rescues him. Doc agrees to leave 1885 after seeing the photograph, but without gasoline, the DeLorean cannot reach 88 mph needed for time travel.
Doc proposes using a steam locomotive to push the DeLorean up to the required speed to return to 1985. While he and Marty inspect a rail spur, they spot a runaway horse-drawn wagon. Doc saves Clara Clayton, altering her death from the original timeline; they quickly fall in love. At a town festival, Buford tries shooting Doc, but Marty thwarts him. Buford then challenges Marty to a showdown in two days; an angry Marty accepts. Doc warns Marty to avoid being provoked by name-calling and lets slip that Marty has a car accident in the future. Doc’s name in the photograph is erased but the date and tombstone remains.
Doc arrives to bid Clara goodbye, but she spurns him, disbelieving his story about being from the future. Despondent, he goes to the saloon for a binge and passes out after one shot of whiskey. In the morning, Buford arrives and calls out Marty, who observes the photograph and sees “Clint Eastwood” (his 1885 alias) appear on the tombstone, so he refuses to duel Buford. Doc revives and tries fleeing with Marty, but Buford’s gang forces Marty into the duel. Marty fools Buford into believing he fatally shot him, then knocks him into a wagon of manure. Buford is arrested for an earlier robbery.
On the train for San Francisco, Clara overhears a conversation about how heartbroken Doc is. Clara applies the emergency brake and walks back to Hill Valley. She discovers Doc’s scale model of the time machine at his shop and, realizing he was telling the truth, rides after him. Using the stolen locomotive, Doc and Marty push the DeLorean along the spur line. Clara boards the locomotive while Doc climbs toward the DeLorean. Seeing Clara, Doc encourages her to reach him, but she falls, hanging by her dress. Marty, in the DeLorean, passes his futuristic hoverboard to Doc and he uses it to save Clara, coasting away as the locomotive falls off an unfinished railroad bridge and into a ravine.
Marty is transported to 1985, arriving on the now-completed bridge, and escapes from the powerless DeLorean just before it is struck by an oncoming train and destroyed. The timeline has returned to normal, and Marty finds Jennifer sleeping on her porch. Marty has learned to no longer be goaded and avoids a street race with Douglas J. Needles, thus preventing the future automobile accident Doc warned him about. Jennifer opens the fax message she kept from 2015 and watches as its text regarding Marty’s firing disappears.
As Marty and Jennifer examine the DeLorean wreckage, a steam locomotive equipped with a flux capacitor appears, operated by Doc, Clara, and their two young sons Jules and Verne. Doc gives Marty a photo of them standing next to the town clock that was taken in 1885. Jennifer asks about the fax, and Doc says it means that the future has not yet been written. Doc and his family say goodbye and depart in the locomotive, which lifts off the tracks before disappearing into an unknown time.
