Mesmero, a mutant hypnotist, escapes from prison and flees to Canada while officials send some cloaked Sentinels to chase him. Alpha Flight intercepts the impending battle and fights off the Sentinels as well as Mesmero. They win the brawl, but not before Puck is gravely injured. Alpha Flight then rushes to bring Puck to Scramble, who may be able to save him.
