x men days of future past
In a dystopian future, robots known as Sentinels are exterminating mutants and oppressing humans who harbor the genes that lead to mutant offspring. A small band of mutants manages to evade the Sentinels due to Kitty Pryde, who can project a person's consciousness back in time to deliver warnings.
Pryde's group rendezvous with Storm, Wolverine, Professor Xavier and Magneto in a monastery in China. They decide to send Wolverine's consciousness back to 1973 to prevent Mystique from murdering Bolivar Trask, the designer of the Sentinels. The assassination will make Trask a martyr, Mystique will be captured and her DNA will be reverse-engineered to create the formidable Sentinels of the future. Xavier advises Wolverine to seek out his and Magneto's younger selves for aid.
Wolverine wakes up in 1973 and travels to the X-Mansion, where he encounters Xavier and Hank McCoy. Xavier's Institute for Gifted Youngsters is closed due to most of the students having died in the Vietnam War. Xavier, now a broken man, has regained his ability to walk due to a serum created by McCoy that, as a side effect, suppresses his telepathic powers. Wolverine explains his mission and persuades Xavier to free Magneto — who has been accused of assassinating John F. Kennedy — from a prison cell beneath The Pentagon. They enlist Peter Maximoff, a mutant with superhuman speed, to assist them.
Trask unsuccessfully lobbies his Sentinel program to Congress. In Saigon, Mystique prevents a young William Stryker from appropriating a group of mutant G.I.s for Trask's research. Mystique investigates Trask and discovers he has been capturing and experimenting on mutants. Xavier, Magneto, Beast, and Wolverine go to intercept Mystique in Paris.
In Paris, the Americans and Vietnamese are negotiating the end of United States' involvement in the Vietnam War. Mystique impersonates a general to infiltrate a meeting with Trask, who attempts to sell his Sentinel technology to the Communists. Xavier, Magneto, Beast, and Wolverine arrive as she is about to kill him. Believing that the dark future can only be avoided through Mystique's death, Magneto tries to kill her; she flees out a window. The fight spills onto the streets in front of onlookers and cameras. Mystique slips away in the confusion.
Wolverine's encounter with Stryker causes his future body to react violently, injuring Kitty.
Although Trask is saved, the world is horrified by the existence of mutants. President Richard Nixon approves Trask's Sentinel program and arranges an unveiling in Washington, D.C. Trask's scientists recover Mystique's blood from the battle site in Paris. Afraid that Trask could yet create the formidable future Sentinels, Magneto intercepts the prototypes and laces their polymer-based frames with steel.
At the mansion, Xavier stops taking his serum and regains his powers. Through Wolverine, Xavier speaks to his future self and is inspired to struggle for human-mutant peace once again. He uses Cerebro to track Mystique, now heading to Washington, D.C.
