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.

Q: Generate a question that has the following answer: Tiangong for the following movie plot: Dr. Ryan Stone (Sandra Bullock), a biomedical engineer from Lake Zurich, Illinois, is aboard the NASA space shuttle Explorer for her first space mission, STS-157. Veteran astronaut Matt Kowalski (George Clooney) is commanding his final mission. During a spacewalk to service the Hubble Space Telescope, Mission Control in Houston warns the team about a Russian missile strike on a defunct satellite, which has inadvertently caused a chain reaction forming a cloud of debris in space. Mission Control orders that the mission be aborted and the crew begin re-entry immediately because the debris is speeding towards the shuttle. Communication with Mission Control is lost shortly thereafter. High-speed debris from the Russian satellite strikes the Explorer and Hubble, detaching Stone from the shuttle and leaving her tumbling through space. Kowalski, using a Manned Maneuvering Unit (MMU), recovers Stone and they return to the Explorer. They discover that it has suffered catastrophic damage and the rest of the crew is dead. They decide to use the MMU to reach the International Space Station (ISS), which is in orbit about 1,450km (900mi) away. Kowalski estimates they have 90 minutes before the debris field completes an orbit and threatens them again. En route to the ISS, the two discuss Stone's home life and her daughter, who died young in an accident. As they approach the substantially damaged but still operational ISS, they see that its crew has evacuated in one of its two Soyuz modules. The parachute of the remaining Soyuz has deployed, rendering the capsule useless for returning to Earth. Kowalski suggests using it to travel to the nearby Chinese space station Tiangong, 100km (60mi) away, in order to board a Chinese module to return safely to Earth. Out of air and maneuvering power, the two try to grab onto the ISS as they fly by. Stone's leg gets entangled in the Soyuz's parachute cords and she grabs a strap on Kowalski's suit, but it soon becomes clear that the cords will not support them both. Despite...

Q: Generate a question that has the following answer: Revolvers. for the following movie plot: Sheriff Pat Garrett (Thomas Mitchell) welcomes his old friend Doc Holliday (Walter Huston) to Lincoln, New Mexico. Doc is looking for his stolen horse and finds it in the possession of Billy the Kid (Jack Buetel). Despite this, the two gunfighters take a liking to each other, much to Pat's disgust. This does not prevent Doc from trying to steal the horse back late that night, but Billy is waiting for him outside the barn. After that, Billy decides to sleep in the barn, and is shot at. He overpowers his ambusher, who turns out to be curvaceous young Rio McDonald (Jane Russell), out to avenge her dead brother. The next day, a stranger offers to shoot Pat in the back while Billy distracts the lawman. However, he is only setting the Kid up. Billy, suspicious as always, guns him down just before being shot himself. There are no witnesses, and Pat tries to arrest Billy. Pat does not understand when Doc sides with the Kid. As the pair start to leave, Pat shoots Billy, forcing Doc to shoot the gun out of his hand and kill two of Pat's men. Doc flees with Billy to the home of Rio and her aunt, Guadalupe (Mimi Aguglia). With a posse after them, Doc rides away. Instead of killing the unconscious Kid, Rio instead nurses him back to health, a process that takes a month. By the time Doc returns, Rio has fallen in love with her patient. Doc is furious that Billy has stolen his girlfriend. After Doc's anger subsides a bit, the Kid gives him a choice: the horse or Rio.

On the trail, they find themselves being pursued by Pat and a posse. The pair surmise that Rio tipped the sheriff off. Doc kills a few men from long range, but leaves Pat unharmed.
