In the wake of the assault on Cooperstown, Alaska the X-Men are left with nothing but questions surrounding the first mutant birth since M-Day, and how their enemies knew so much about it. After dispatching a team to track down some of the Acolytes, hoping that the trail will lead to Exodus who has thrown in his lot with Sinister's Marauders, Scott contacts Jamie Madrox and his X-Factor team. He senses that what's about to happen will be bigger than the differences that have kept them apart since M-Day. Meanwhile, Predator X, tracks the new mutant to sate it's hunger.
