Jean has been incredibly distracted and unfocused as of late and after the Professor takes a look inside her mind to figure out what's going on, he finds the imprint of some extraterrestrial force, drawing them all near. Trying to solve the situation, he selects a team for a mission in space, leading them to the homeworld of the Shi'ar empire. There, recent events have caused an overhaul, with a man by the name of Vulcan being in power now. This man turns out to be Gabriel Summers, Scott and Alex's younger brother. While the Summers try to figure out the story of their family and what happened to their parents (and is Vulcan really who he seems?), Jean gets drawn closer and closer to the mysterious force.
