Two men break into an old crypt, seeking to dump toxic waste and rob the graves. When an earthquake causes the toxic waste to spill, Catherine Valmont (FranÃ§oise Blanchard), a young woman who died several years ago, is resurrected. She viciously kills the thieves and drinks their blood. As Catherine walks aimlessly through a field, Barbara (Carina Barone) spots her and takes a few photos, though Barbara's boyfriend, Greg (Mike Marshall), takes no notice. Catherine returns to her old house, the Valmont Mansion, and memories of her childhood come back to her, especially her childhood friend, HÃ©lÃ¨ne (Marina Pierro). As Catherine wanders the house, a real estate agent shows an old couple around the property, though they show little interest. After they leave, HÃ©lÃ¨ne calls the house, presumably inquiring about it. However, she hears nothing but a cherished music box, leading her to believe that Catherine may still be alive.The agent later returns to the Valmont Mansion, along with her boyfriend. Catherine interrupts their sex, killing both and drinking their blood. HÃ©lÃ¨ne arrives and is shocked to discover the dead bodies. When she finds Catherine, naked and playing the piano, she assumes that Catherine didn't really die but was actually hidden for the past two years. HÃ©lÃ¨ne washes the blood off Catherine, puts her to bed, and drags the bodies down to the crypt, where she discovers the bodies of the grave robbers. Catherine creeps down and begins to drink the blood from one of the bodies, but HÃ©lÃ¨ne stops her. HÃ©lÃ¨ne cuts her arm and lets Catherine drink her blood, until she can think of a way to supply her friend with blood.Barbara goes around the village asking about the woman in her photograph, but the answer is always the same: It is Catherine Valmont, and she died two years ago. Greg thinks Barbara is making too much of it, and discourages her from investigating further. Meanwhile, HÃ©lÃ¨ne tries to understand what is happening to Catherine, trying to teach her to speak again. Deciding to bring her victims, HÃ©lÃ¨ne pretends to be out of fuel and flags down a helpful motorist, drawing her back to the mansion. HÃ©lÃ¨ne offers the woman a drink and locks her in. The woman soon begins to panic, but HÃ©lÃ¨ne throws her in the crypt, where Catherine grabs her and rips her stomach out. Soon after, Barbara shows up at the Valmont mansion, seeking Catherine. Unsettled by Catherine's behavior, she attempts to phone Greg, but HÃ©lÃ¨ne confronts her. They argue, and HÃ©lÃ¨ne tries to take Barbara's camera. Barbara flees.Catherine, now more in touch with her humanity, realizes that she must be destroyed. She begs HÃ©lÃ¨ne to kill her, but HÃ©lÃ¨ne instead goes back to the village, to bring Catherine another victim. Barbara sees HÃ©lÃ¨ne and eventually convinces Greg to accompany her to the mansion, in order to help Catherine. HÃ©lÃ¨ne tortures the kidnapped girl, but Catherine rejects the unwilling sacrifice and frees her, telling her to return to the village and seek help. Drawn by the screams, Barbara and Greg go to investigate, but they are brutally murdered by HÃ©lÃ¨ne. Overwhelmed by all the death and murder, Catherine attempts suicide, but she is rescued by HÃ©lÃ¨ne, who offers herself to sate Catherine's hunger. Unable to resist, Catherine devours her friend alive.
