In this new adaptation of the myth of "The Beast of Gévaudan", the murders are committed partly by wolves from the East and partly by a man, a cannibalistic, sexual predator. A young doctor, Pierre Rampal, gets to the heart of the mystery. Firstly, to put an end to vile accusations of witchcraft and also because he is in love with Françounette Chastel, the supposed werewolf's daughter.—Happy_Evil_Dude
