In Madrid at the time of the Inquisition, the monk Ambrosio is renowned for his faith and his strength of will, a saint in the eyes of the populace. But when he discovers the beautiful Matilda hidden in his own monastery, all his repressed passions begin to show themselves, and he is soon using the girl, and her powers, in his lust for more innocent prey.
