"When two young women are viciously slain in a luxury high-rise, a beautiful young model (Edwige Fenech of STRIP NUDE FOR YOUR KILLER and HOSTEL: PART II) 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 of THE KILLER MUST KILL AGAIN) 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 becomes his next victim?
