Le Capitaine, le Bosco and two other sailors are dangerous ship wreckers. This time, they have done even worse mischief than usual, for not content to have lured a ship into coastal rocks and plundered it, they have also brutally raped and left for dead the two girls who have survived the wreck. But helped by a mysterious clown, by an exorcist on the beach and by... Satan himself, the two virgins turned she-devils will ruthlessly exact their terrible vengeance.
