The X-Men, mutant heroes sworn to defend a world that hates and fears them, are back! This time, with the help of new recruits The Beast and Angel, they must face evolution itself in the form of their former teammate, Jean Grey. Possessed with the cosmic power of the Dark Phoenix, the resurrected Jean Grey has become a danger to herself, her mutant comrades, and the entire planet. To stave off this imminent threat to humanity, a potential cure is discovered and processed to treat -- and ultimately eliminate -- genetic mutations, once and for all. Now, as the battle lines are drawn, the X-Men, led by Professor Charles Xavier, must contend with both Jean Grey's world-consuming powers, as well as the malevolent Brotherhood, a band of powerful mutants organized under Xavier's former ally, Magneto.

Magneto: No one ever talks about extermination. They just do it. And you go on with your lives, ignoring the signs around you. And then one day, when the air is still and the night is fallen, they come for you. Only then do you realize that while you're talking about organizing and committees, the extermination has already begun. Make no mistake, my brothers, they will draw first blood. They will force their cure upon us. There is only one question you must answer: Who will you stand with?

Logan: You know, sometimes when you cage the beast, the beast gets angry.
