The movie begins with a couple who are staying at a cabin. The guy pisses off some of the locals. He finds his girlfriend dead. The local sheriff, Hadley(Forster) is on the case, along with Marshall(Cummings) and Robson(Lindhome). Robson talks to some of the locals, but they deny having seen or done anything. The police wonder what happened to the girl. It looks like it might be an animal, maybe a wolf. Marshall isn't so sure. He thinks that it's a man. The cops visit the boyfriend before he leaves. Some of the locals report seeing some sort of wolfman. A local woman gets killed by the werewolf creature. John is finding it all hard to believe. He worries about his daughter. He starts drinking, which is bad as he is an alcoholic.
He tries to escape but the guy stabs him. The man dresses up in a werewolf suit and prepares to go out and kill someone else. John chases him. He is in a bad way. Julie comes along and she shoots the werewolf guy. John manages to finish him off. The movie ends with Julie being the new sheriff.
