During a family camping trip in a large national park, Grandpa (Al Lewis) hears some faraway wolf calls and begins waxing nostalgic about his youth in Transylvania. Before long, Grandpa has transformed himself into a wolf so that he can briefly recapture his salad days. Unfortunately, he is unable to reverse the spell--and as a result ends up being hunted down by the park's tireless staff! ~ Hal Erickson, Rovi
