Journey into the dystopian future -- where Sentinels stalk the Earth, and the X-Men are humanity's only hope... until they die!
Thirty-three years in the future, North America is controlled by Sentinels. The few surviving X-Men - Kitty Pryde, Storm, Colossus, Wolverine and Franklin Richards, son of Mr. Fantastic and Invisible Woman, along with Magneto, plan to change history by having Rachel Summers exchange the psyche of the adult Kate Pryde with that of her younger self.
In the present, Kitty Pryde succeeds at her first Danger Room test, only to faint a moment later. When she awakes again, she tells the X-Men she is the adult Kate. She explains that she’s from the future and that the X-Men must prevent the murder of Senator Robert Kelly at the mutant hearing in Washington today. The X-Men are unsure whether to believe Kate but Xavier is at the hearing as well and only he can tell the truth of Kate’s words.
In the meantime, the new Brotherhood of Evil Mutants, under the leadership of Mystique and with Blob, Pyro, Avalanche and Destiny as their members, prepares to assassinate Sen. Kelly. The X-Men join Xavier in Washington and, a moment later, the Brotherhood appears, intending to kill Kelly. The X-Men move to oppose them.
In the future, the X-Men have escaped the camp, and suffered two fatalities and plan to strike back at the Sentinels.
