Perché quelle strane gocce di sangue sul corpo di Jennifer?

When 2 young women are viciously slain in a luxury high-rise, a beautiful young model (Edwige Fenech) moves into one of their vacated apartments - and soon finds that she is now being stalked by the mysterious killer! The suspects include her ex-husband (a member of a group sex cult), a predatory lesbian neighbor, the deformed son of a sinister widow, and even the building's handsome architect (George Hilton) who suffers from a paralyzing fear of blood. Can she expose the masked maniac with a taste for luscious women and depraved murder before she become his next victim? The film is directed by Giuliano Carnimeo under pseudonym Anthony Ascott, and written by Ernesto Gastaldi. (jakelijan virallinen teksti)
