Having recently escaped the clutches of her ex-husband's sex cult, a beautiful model is stalked by a masked killer whose previous victims include the former occupants of her new apartment.

Beautiful young model Jennifer Lansbury and her goofy friend Marilyn Ricci move into a swanky high-rise apartment after the previous tenant gets brutally murdered. Pretty soon Jennifer is being stalked by the mysterious killer. Probable suspects include a predatory lesbian neighbor, a weird old woman and her deformed son, and even the building's handsome architect who suffers from a severe blood phobia.—Woodyanders

After the murder of a call girl in a building, the dweller Mizar Harrington, who is a fighter and stripper in a nightclub, is drowned in her bathtub by the killer. The administrator and architect Andrea Antinori offers the apartment to the models Jennifer Lansbury and Marilyn Ricci for a reasonable price and they move to the flat. Jennifer is the ex-wife of the hippie Adam, who forced her to practice group sex and now harasses her all the time. Soon Andrea hits on Jennifer and she becomes his girlfriend. When Adam is found dead in Jennifer's apartment, Andrea becomes the prime suspect of Commissioner Enci, who assigns his Assistant Commissioner Renzi to follow him everywhere. However, Jennifer believes Andrea is innocent and suspects that one of her neighbors might be the killer.—Claudio Carvalho, Rio de Janeiro, Brazil
