A fire-breathing preacher and a pair of police officers all have something grisly in common; they're the latest victims in a series of bizarre ritualistic murders. The police think that the killings are the work of the local street gang, The Lobos, who pattern their organization as if they are a real wolf pack. But a down on his luck teacher suspects that the killings may be the work of the Reuzenwolf, a species of werewolves that his grandfather used to talk about in his homeland of Holland. With panic growing in the streets from the continued attacks, Hank's claims of real life werewolves fall on deaf ears with the authorities, and he soon finds himself alone in a fight against an advancing horde of lycanthropes.
