grisly and potent shocker from jean rollin regard how a dead young lady of two year and the body surprisingly fresh without rot during that time ( . ) and be revive from a spill can of toxic waste and put there by some corpse looter and after a minor earthquake . she have vampire mentality ( . not to mention terrify fingernail which can tear into flesh with ease ) meaning this uncontrollable thirst for flesh and blood from human being . the girl and catherine ( françoise blanchard ) and call the evil inside . a blood sister and helene ( marina pierro ) do not know her best friend from childhood have be dead and after a phone call lead to catherine discovery ( hear the sound box play music both listen to a child ) she race to the villa to see about her . what helene see be a bloody mess and several unfortunate who become blood donor to catherine unhinged feeding time . helene will slowly grow obsess with keep her beloved sister alive do whatever it take and mean lure those unaware of what await them and to become victim for catherine . a photographer and barbara ( carina barone ) see catherine walking in a daze upon leave her crypt and take a snapshot . that snapshot fascinate her . the image that compel her to seek out the identity of catherine might seal her fate . perhaps and barbara husband ( mike marshall ) will be able to keep her from harm before it too late . or and will barbara obsession with learn more about catherine and and take more picture of her and lead to a gruesome demise . what the people around this villa need to worry about be helene mad desire to find fresh body for her catherine . the most important story element and and what i feel be the most haunting aspect and be that a day go by catherine be realize the monster she become when the evil hunger return . she wish to be put away and beg for helene to see this through . the idea of lose her friend a second time and and not be able to come to term with the fact that catherine be dead and i think helene be the tragic character of the film . friendship and love seem to be very powerful emotional drive within this plot while rollin often cut into this with a furious rage when he show catherine eat habit . she just doesn not suck blood with any form of sophistication and but tear into her meal like a crazed and starve animal . and and believe me and the feasting be extremely unsettling a we watch the flesh of throat and arm and and stomach rip with vengeance by catherine who seem out of control with her sens with the primal urge to munch operating in overdrive . the direction be rather straight forward and i felt and and follow a project path . it end about the way i imagine it would . the end leave only despair for the victim who just wish for the blood lust and torment to leave her .
