A man plans to rob the banker of a village that believes it is being subject to werewolf attacks. When the banker interrupts him opening the safe, he stabs the banker, but not before he sees the werewolf tattoo on his arm and cries out. When the villagers gather around him he tells them about the werewolf tattoo and dies. The man gets the idea of capturing the village idiot and tattooing a werewolf on his arm so as to pin the blame for the killing on him. He succeeds in doing this, but then the idiot transforms into a real werewolf and kills him.
