Erika and her friends like to research about paranormal activities through old manuscripts, incidents and visiting monasteries, castles and other haunted places. But the other two girls don't really know the motivation of evil Erika to resurrect Countess Elisabeth Bathory, a satanic witch who alongside her followers ruled over life and death in Medieval Europe. Bathory used to have a werewolf as a slave named Waldemar. When she comes back to life as Erika sacrifices one of her friends, she wants to slave hin back again. But Karen, the other young woman falls in love with Waldemar and helps him into his epic battle against the evil company. Ok, it was about time to return to one of my favorite genre of fantasy movies. Great cinematography and a nice atmospheric musical score with some sound ripped from Ennio Morricone's ''One upon the time in the West''. Cool gem for Paul Naschy fans and terror genre enthusiasts!
