Mastermind has been dispatched by Magneto to find the X-men but has failed to turn up any leads. He and Quicksilver return to Magneto's new base, Asteroid M. Magneto is focused on destorying the X-men and quickly silences any other ideas that Quicksilver, Toad or Scarlet Witch may have. Magneto has come up with a new plan to find the X-men. His plan is to use the Toad to trap the X-men.
Meanwhile the X-men try to relax and watch a little T.V. to take their mind off the trouble with Professor X's health or Magneto's mutants. On TV they spy a young track athletic with incredible leaping powers. The other athletes notice as well and turn into an angry mob. The X-men are convinvce he is a new mutant in need of help and rush to his aid.

Back on Asteroid M, Angel is tortured to reveal the lair of the X-men but resists due to Professor X's training. Toad feels compelled to returned to Magneto and summons a drop ship that returns him and the X-men to Asteroid M. Magneto plans to blow the X-men out of an airlock into the vacuum of space but Scarlet Witch prevents her. The X-men are able to rescue Angel and escape in a landing pod. When the X-men return they found Professor X in good health. He had faked losing his power to see if they could manage on their own as a sort of final exam.
