Movie plot title: Back to the Future Part II Movie plot: 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 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 dramatically: Biff has become wealthy and corrupt, and has changed Hill Valley into a chaotic dystopia....

Movie plot title: Sleepers Movie plot: Lorenzo "Shakes" Carcaterra, Tommy Marcano, Michael Sullivan, and John Reilly are childhood friends in Hell's Kitchen, New York City in the mid-1960s. The local priest, Father Robert "Bobby" Carillo, serves as a father figure to the boys and keeps an eye on them. However, they start running small errands for a local gangster, King Benny. In the summer of 1967, their lives take a turn when they nearly kill a man after pulling a prank on a hot dog vendor. As punishment, the boys are sentenced to the Wilkinson Home for Boys in Upstate New York. There, the boys are systematically abused and raped by guards Sean Nokes, Henry Addison, Ralph Ferguson, and Adam Styler. The horrifying abuse changes the boys and their friendship forever. During the boys' stay at the facility, they participate in Wilkinson's annual football game between the guards and inmates, one that the latter lose on purpose to avoid reprisals from the former. Michael convinces Rizzo, a black inmate, that they should play as hard as they can to show the guards they can fight back. Rizzo agrees, and helps to win the game. As a result of this, Shakes, Tommy, Michael, and John are all beaten and thrown into solitary confinement for several weeks, and the guards beat Rizzo to death. Shakes insists that they should publicly report the abuse, but the other boys refuse. They all therefore vow never to speak of the horrors and abuse the guards put them through once they're all out. Fourteen years later, John and Tommy, now career criminals, encounter Nokes by chance in a Hell's Kitchen pub and kill him in front of witnesses. Michael, who has become an assistant district attorney, arranges to be assigned to the case, secretly intending to botch the prosecution. He and Shakes, who is writing for a newspaper, forge a plan to free John and Tommy and get revenge on the guards who abused them.
