Count Yorga (Robert Quarry) has moved into a big mansion that's next to an orphanage. In the first scene a young boy is attacked by vampire women who emerge from their graves. It looks as if he's killed but he soon shows up afterwards, unharmed. But he's hypnotized and does Yorga's bidding, as we find out later. Yorga has his sights on Cynthia Nelson (Mariette Hartley), who he has fallen in love with, and wants to make her his wife. In a weird scene where she's staying with her family, they are attacked by vampires and the memory is erased from her mind. She awakens in Yorga's mansion, in different clothes,and told that she's recovering from a car accident. She doesn't question this. A deaf woman who works at the orphanage had seen the slaughtered bodies afterwards and calls the police, though they don't believe her at first. One of the detectives, who has in interest in Cynthia, starts an investigation of his own and comes to the conclusion that the Count may indeed be a vampire.
This is one of those cases where the sequel is better than the original. Yorga's coven of vampire women are horrendous looking and creepy, the opposite of what you'd expect. And when he is about to bite someone his complexion goes all pasty and he has a mouthful of sharp teeth, not the typical vampire fangs. I also liked that the movie has a good sense of humor about it, especially the vampire expert scene in which he exclaims he "wants nothing to do with yoga, he got stuck in in the lotus position". Most of all, I like the unhappy twist ending. I wasn't expecting that. Recommended.
