A young man, Peter, returns to Austria in search of his heritage. There he visits the castle of an ancestor, a sadistic Baron who was cursed to a violent death by a witch whom the Baron had burned at the stake. Peter reads aloud the incantation that causes Baron Blood to return and continue his murderous tortures.
