Chaos erupts in Indianapolis! And while the Grendels usually ride chaos like a bronco, this time they find themselves unable to saddle up! Their chief, Hack, has fallen for one of the locals, a nurse named Dana. Problem is, Dana's son is the one creating the chaos; he's picking off Grendels like a madman vigilante. Hack's gotta decide -- is he willing to lose his status as Grendel Chief, or lose the woman he loves?
