In this atmospheric but forgettable Hammer horror movie, a white cloaked cult of vampires kidnap a woman on her honeymoon. Her confused hubby teams up with a vampire hunter to save her. In the end, the vampires are attacked and killed by BATS! HUH?!? Director Don Sharp also did the underrated The Curse of the Fly. Screenwriter John Elder (AKA: producer Anthony Hinds) also wrote many Hammer films such as The Evil of Frankenstein.
