 A new war between humans and mutants begins after an attempted assassination of the President of the United States. Now, all the mutants must fight together against a common enemy: General William Stryker. Stryker, to further his plan to eradicate all mutants, uses radical methods to get some information from Magneto, and plans an attack to Professor Xavier s school. On the night of the attack, Wolverine is left alone to  babysit  the young students (Jean Grey and Storm are looking for the mutant assassin, and Xavier is in Magneto s plastic prison, having left Cyclops in its lobby). The plot goes on with a lot of action and many revelations, largely following the comic books.
