Karnstein Castle stands like a bird of prey on the highest point of the hills that surround the village below. A huge monolithic reminder to all those who see it of the power of the family who have lived there for centuries. By day the village of Karnstein is a peaceful place but by night an unimaginable evil roams free. Villagers are found dead their throats ripped open & bodies drained of blood. Young girls disappear & are never seen again. Rumour has it that they are taken to the castle for the pleasure of Count Karnstein the last surviving member of the family. Into this strange place come beautiful identical twins Maria & Frieda. While Maria lives a blameless life Frieda is drawn to the castle & Count Karnstein. A man rarely seen in daylight a man steeped in Satanic ritual & the blood of beautiful young girls. Before long Frieda & Karnstein unleash a reign of bloody terror on the villagers & no one it seems is strong enough to stop them.
