A trio of nerdish students accidentally invoke a supernatural spell -- and presto! Familiar Justice League nemesis Solomon Grundy is revived from his "sleep of death." Going on a rampage, Grundy cannot be stopped by the Leaguers. Their only hopes lie in the only person who'd ever befriended the villainous Grundy -- former JL member Hawkgirl, now living in seclusion as her "civilian" persona Shayera. The question: Will Hawkgirl be willing to vanquish Grundy, to whom she owes her very life? Clips from several previous episodes are sprinkled throughout this pivotal Justice League Unlimited adventure.
