Cyclops and Madelyne Pryor are transporting a group of American and Canadian scientists to the Arctic Circle, when their plane is struck down by an unknown source. While training in the Danger Room, Rachel Summers sees this happen in a psi-flash, and the X-Men deal with an out-of-control Danger Room scenario. She believes her father's attack to have something to do with Shaman of Alpha Flight, who at this very moment is dealing with the problems of some of his own teammates. Without warning, the goddess Snowbird appears before him, seriously wounded. Before Shaman can tend to Snowbird, Rachel Summers attacks him and his fellow teammates.

The X-Men arrive and aid Alpha Flight while Xavier succeeds in calming Rachel down. Snowbird regains consciousness and reveals that Cyclops' plane was struck down at the same moment she was. The two teams of super-heroes decide to work together to find Cyclops and the missing scientists.
