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.... My question: What does Marty turn down?

Plot title: Schindler's List Movie plot: In Krakow during World War II, the Germans had forced local Polish Jews into the overcrowded Krakow Ghetto. Oskar Schindler, an ethnic German, arrives in the city hoping to make his fortune. A member of the Nazi Party, Schindler lavishes bribes on Wehrmacht (German armed forces) and SS officials and acquires a factory to produce enamelware. To help him run the business, Schindler enlists the aid of Itzhak Stern, a local Jewish official who has contacts with black marketeers and the Jewish business community. Stern helps Schindler arrange financing for the factory. Schindler maintains friendly relations with the Nazis and enjoys wealth and status as "Herr Direktor", and Stern handles administration. Schindler hires Jewish workers because they cost less, while Stern ensures that as many people as possible are deemed essential to the German war effort, which saves them from being transported to concentration camps or killed. SS-Untersturmfuhrer (second lieutenant) Amon Goth arrives in Krakow to oversee construction of Paszow concentration camp. When the camp is completed, he orders the ghetto liquidated. Many people are shot and killed in the process of emptying the ghetto. Schindler witnesses the massacre and is profoundly affected. He particularly notices a tiny girl in a red coat one of the few splashes of color in the black-and-white film as she hides from the Nazis, and later sees her body (identifiable by the red coat) among those on a wagon load of corpses. Schindler is careful to maintain his friendship with Goth and, through bribery and lavish gifts, continues to enjoy SS support. Goth brutally mistreats his Jewish maid Helen Hirsch and randomly shoots people from the balcony of his villa, and the prisoners are in constant fear for their lives. As time passes, Schindler's focus shifts from making money to trying to save as many lives as possible. To better protect his workers, Schindler bribes Goth into allowing him to build a sub-camp. As the Germans begin to lose the war, Goth is... My question: Schindler must flee from what?

Plot title: Infernal Affairs Movie plot: Infernal Affairs focuses on a police officer named Chen Wing-yan, who goes undercover into a triad, and a triad member Lau Kin-ming, who infiltrates the Hong Kong Police Force. Each mole has been planted by the rival organisation to gain an advantage in intelligence over the other side. The more the moles become involved in their undercover lives, the more issues they have to cope with. The prologue opens with the introduction of triad boss Hon Sam, who sends a number of young gangsters to the police academy as moles, among whom include a young Lau. Concurrently, a young Chen joins the police force but is seemingly expelled from the academy even though he manages to impress Superintendent Wong Chi-shing. In reality, Chen has become an undercover agent reporting only to Wong. Over the course of ten years, Chen experiences great stress from his undercover work while Lau quickly rises through the ranks in the police department. The film begins with a meeting between Chen and Lau in a hi-fi store without either of them knowing the other's identity. Wong and his team interrupt a deal between Hon Sam and a Thai cocaine dealer after receiving a tip-off from Chen using Morse code. However, Lau alerts Hon, giving him enough time to order his minions to dispose of the cocaine, eliminating solid evidence of the drug deal. After the incident, Wong and Hon are both aware that they each have a mole within their respective organisations, placing them in a race against time to root out the other mole. Later, Chen sees Hon conversing with Lau at a cinema but does not see Lau's face clearly; he ultimately fails to capture Lau.
