La morte vivante (1982)

When they were children, Catherine [Francoise Blanchard] and Hélène [Marina Pierro] swore blood oaths that they would always love each other and, whomever died first, the other would follow. It was Catherine who was first to go. She was laid to rest in the Valmont crypt underneath the family castle. Two years later, however, some men reawaken Catherine while illegally dumping toxic waste in the Valmont vault. Unfortunately, Catherine now requires the blood of the living to survive.
