Jess Franco returns with another campy gore-fest featuring the strange goings-on in a tiny hamlet called Holfen. When women wind up knifed and gouged in the village, everyone thinks the deaths are due to a curse wielded by a cruel 17th century baron. Von Klaus heir Ludwig is distantly related to the royal, which makes him the target of suspicion. Can he clear his name, or will he wind up giving in to his dark side?
