After the death of their parents, the Gelhorn twins, the sensual and cunning Frieda and the timid, conservative Maria, go to live in the village of Karnstein with their puritanical uncle Gustav Weil. Gustav is head of the witch-hunting Brotherhood and opposes the current Count Karnstein. The Count, bored of petty Satanic rituals, offers his soul to the Devil in return for greater pleasures. The blood of a woman he has just killed drops down into the crypt of his ancestor Mircalla and she appears to him as a wraith, putting the bite of vampirism on him as they make love. Karnstein then seduces and makes a vampire of Frieda.
