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.
Unfortunately the movie Baron Blood is not yet available on HBO Max.
