In the future, robots known as Sentinels are exterminating mutants and their human allies. A band of mutants, including Kitty Pryde, Colossus, Iceman, Bishop, Warpath, Blink and Sunspot, evade the Sentinels due to Pryde's ability to send a person's consciousness to 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 Dr. Bolivar Trask, creator of the Sentinels.
