The first mutant birth since M Day has occurred, and the X-Men are already behind in the race to secure the child. They don't even understand the significance, but the mutant-hating Purifiers and Sinister's Marauders have already both attempted to take control of the child. In an attempt to learn what's going on, Cyclops has asked Rictor, who has been powerless since M-Day, to infiltrate the Purifiers, while the rest of the X-Men attempt to track down the Acolytes, since they have traditionally close ties to the Marauders. But surprisingly, the Mutant Birth has given hope to the Mutant race. Forge reports that in his scans of time and space, he's determined two realities in which Mutants will not become extinct. To explore these possibilities, Madrox sends to duplicates in to scout when someone decides to hitch a ride.
