The Gist: A Vampire Hunter is sent to solve the deaths of women in a town from rapid aging.
Clarification: This is best described as if Countess Dracula was a swashbuckling action movie. Only difference being that these are actual traditional vampires (the supernatural fanged kind) though the results are the same (blood drinking to preserve youth instead of nourishment). The more they drink the younger they get. It is even stated during the film that the family that the murders revolve around are distantly related to the Karnsteins of Hammers other series of films.
Selling Point: Kronus' assistant is played by the super sexy bond girl Caroline Munro
Female Vampire Factor: This film falls under more of a "who done it" than your traditional Hammer vampire film we're used to where you know from the beginning who the vampire is but no one else in the film does so in this case you don't actually see your vampires till the very end. There is some bait and switch to keep you guessing but in the end (SPOILER ALERT!) it turns out that the old bed ridden widow of Captain Kronus' friend Lord Durward "Lady Durward" (Wanda Ventham) is in fact the vampire.
