Cyclops and Wolverine struggle to deal the growing threats facing mutants, while still keeping X-Force's existence a secret from the X-Men. Warpath is out for vengeance, Wolfsbane is still missing, and X-23 keeps cutting off pieces of Vanisher. But worst of it all? One mutant's deadly actions will put mutantkind squarely back in the crosshairs of humanity. Things were bad before, but now they are about to get a hell of a lot worse.
