Buio Omega (1979)

Frank Wheeler (Kieran Canter), a young son of a wealthy family, has lost his parents since childhood, and only the housekeeper Alice (Franca Stoppi) lives alone in a mansion in the country with him. At this time, Frank and the beautiful Anna (Cinzia Monreale) fall in love, but their love is envied by Alice. Carried away by jealousy, Alice resorted to voodoo witchcraft, which eventually led to Anna's painful death. Frank, who lost his lover, was heartbroken, and his strong yearning prompted him to dig up Anna's body and make it into a lifelike specimen. From then on, Frank embarked on a dark and bloody road, until one day, Elena (Cinzia Monreale), who looks similar to his sister Anna, appeared in front of Frank and Alice.
