Mystique calls Wolverine to warn him that Maverick's daughter, Kristie, is in danger. The two of them infiltrate Weapon X and have to fight Maverick and Sabretooth - and some old ghosts from the past as well.

In the twenty-year future, Professor Xavier and his new X-Men fight the Sentinels and come across Polaris, who lives alone and traumatized in a destroyed Genosha. Charles learns how Genosha was destroyed and how Polaris was the only survivor. In the present, Wolverine, Forge and Shadowcat infiltrate an MRD base to investigate the Master Mold, only for the former two to get caught which led to the Wolverine-type Sentinels that the future X-Men just evaded.
