This low budget first film from director Jean Rollin is in reality two very loosely-connected, surreally erotic shorts about vampirism. In the first, three Parisians including a psychoanalyst try to convince four neurotic sisters living in a decaying country chateau that their belief that they are 200 year old vampires is false. The alluring young women are influenced and controlled by a enigmatic disembodied voice which turns out to be the an aging, aristocratic lord of the manor, whose motives are unclear but clearly perverse. Local rustics unite to hunt down and kill the sanguine siblings.
