Female vampires

This movie was an interesting variance to the vampire tale. These vampires are all female. The Countess, played fabulously by Delphine Seyrig, was the elder "leader of the pack" as it were. Her young protege, played by Andrea Rau, was the Countess' lover and helpmate. This lesbian vampire pair attached themselves to a young couple, played by Danielle Oiumet and John Karlen (who, in his later years, played the husband of Lacey in the tv show Cagney and Lacey). The acting from these two was particularly bad and the only redeeming feature was the performance by Seyrig. Back to the plot, the lesbians looking for new blood insinuated themselves into the life of the couple and the way for the Countess to get to the newly married woman was to show her how terrible men are. So the protege sleeps with the man, dies in the process, is discovered by the wife and now the Countess needs a new protege. A pretty, young, disillusioned, blonde fits the bill quite well. Lowlife husband dies, Countess and her new lover whisk away to another town only to crash in an accident and the Countess is speared through the heart as she is thrown from the vehicle. Now, the blonde lives on and is seen carrying on the bloodsucking life of the Countess.
The vampire as seducer takes on a new life when the vampire is a woman, but interestingly enough, the females are STILL the victims.
