Taglines: Getting back was only the beginning.
On October 26, 1985, Dr. Emmett Brown arrives in his flying time machine and persuades Marty McFly and his girlfriend, Jennifer Parker, to come back to the future with him to help their future children. Biff Tannen witnesses their departure. They arrive on October 21, 2015, where Doc electronically knocks out Jennifer and leaves her asleep in an alley, explaining that she should not have too much knowledge of future events. He has Marty pose as his own son and lookalike Marty Jr to refuse an offer to participate in a robbery with Biff’s grandson Griff, thus saving both of Marty’s children from prison.
Marty switches places with Marty, Jr., and refuses Griff’s offer, but Griff goads Marty into a fight. Griff and his gang are arrested, saving Marty’s future children. Before rejoining Doc, Marty purchases an almanac containing the results of major sporting events from 1950 to 2000. Doc discovers it and warns Marty about attempting to profit from time travel, but before Doc can adequately dispose of it, they are interrupted by the police, who have found Jennifer incapacitated and are taking her to her 2015 home. They pursue, as does Biff, who has overheard their conversation and picked up the almanac which Doc discarded.
Jennifer wakes up in her 2015 home and hides from the McFly family. She overhears that her future self’s life with Marty is not what she expected, due to his involvement in an automobile accident. She witnesses Marty being goaded by his co-worker Douglas J. Needles into a shady business deal, which leads to Marty’s firing. Attempting to escape the house, Jennifer encounters her 2015 self and they both faint. While Marty and Doc attend to her, Biff steals the time machine and uses it to travel back to 1955 and give the almanac to his younger self to get rich betting, then returns to 2015. Marty, Doc, and an unconscious Jennifer return to 1985, unaware of Biff’s actions.
The 1985 to which they return has changed drastically: Biff has become wealthy and corrupt, and has changed Hill Valley into a chaotic dystopia. Marty’s father, George, was killed in 1973, and Biff has forced Marty’s mother, Lorraine, to marry him. Doc has been committed to an insane asylum. Marty and Doc determine that 2015 Biff took the time machine to change 1985, and Marty learns from 1985 Biff that he got the almanac on November 12, 1955. Biff attempts to kill Marty, but Marty flees and returns to 1955 with Doc.
