The humans have been trying to find a "cure" for the mutants for decades, and now they finally have it. A top-secret laboratory came up with a formula that takes away their powers and turns them into regular men and women. However, while the vast majority of the mutants agrees to willingly give out their unique abilities, the rest of them aren't so quick to do that. Magneto, one of the most powerful mutants on the planet, leads a small yet extremely strong crew into a devastating fight against humanity. They want to put a stop to this as Magneto believes the humans will enslave them after their powers are gone. Xavier is the only one who can oppose his old friend and win this battle.
