In the future, robots known as Sentinels are exterminating mutants and their human allies. A band of mutants evades the Sentinels with the help of Kitty Pryde, who has the ability to send a person’s consciousness into the past. Pryde’s group convenes with Logan,Storm, Professor Charles Xavier, and Erik Lehnsherr at a monastery in China. Pryde sends Logan’s consciousness 50 years back in time to 1973 to prevent Mystique from assassinating Bolivar Trask, creator of the Sentinels. Following the assassination, Mystique was captured, and her DNA was used by Trask’s company to improve the Sentinels, whose ability to adapt to any mutant power makes them almost invincible. Xavier and Lehnsherr advise Logan to find both of their younger selves for help.
