Karnstein Castle stands just like a bird of victimize the highest point of the hills that surround the village below. A huge monolithic reminder to all or any those who view it of the energy of the family who have lived there for centuries.

By time the town of Karnstein is normally a peaceful place, but by evening, an unimaginable wicked roams free. Villagers are located useless, their throats ripped open up and bodies drained of blood. Young girls vanish and are by no means seen again. Rumour provides it that they are taken to the castle for the enjoyment of Count Karnstein, the final surviving member of the family.

Into this strange place, come beautiful identical twins Maria and Frieda. While Maria lives a blameless existence, Frieda is attracted to the castle and Count Karnstein. A man rarely observed in daylight, a man steeped in Satanic ritual as well as the bloodstream of beautiful girls.

In a short time Frieda and Karnstein unleash a reign of bloody terror in the villagers, and no one, it seems, is strong more than enough to stop them.
