In the small town of Tannersville, a bloody menace hunts townsfolk. Megalonyx, Master of the Winter World, is a carnivorous snow creature, hungry for human flesh. He arrives during the winter solstice, and this two-ton predator will not be stopped without an epic battle that could leave behind a pile of corpses--and the people of Tannersville aren't exactly soldiers. In the midst of chaos, young Bill Meyers has his first sexual experience with "Slutty Suzy," but things don't go quite as planned. His younger brother, Kyle, has read one too many comic books as he sets out to fight the evil beast. When people doubt the existence of Megalonyx, they accuse Bogy Wilson, whose uses homemade moonshine to keep him sane. Religious Sheriff Gibbs wants to keep peace in town and does so by covering up all the spilled blood. Then, there's Frank Porter, a sensible newsman who's trying to find some normalcy amidst the chaos while falling in love with the beautiful Melanie Cuttles. Despite panicked rumors, Megalonyx does exist, and he's coming for everyone in Tannersville unless someone solves the puzzle that will make him stop.
