Director Mario Bava's second thriller revolves around a fashion salon owned by wealthy Cristina (
Eva Bartok) and her greedy lover Max (
Cameron Mitchell). The salon is a front for cocaine-trafficking and blackmail, so when model Isabella (Lea Kruger) is viciously strangled, leaving a detailed diary behind, many of the people connected with the salon become very nervous. Isabella's roommate Nicole (Arianna Gorini) finds the diary and soon has her throat clawed out with a piece of medieval armor. Peggy (Mary Arden), who borrowed abortion money from Isabella, is tortured and has her face pressed into a red-hot iron. The bodies continue to pile up until a conspiracy is exposed and the perpetrators start getting their just desserts. Luciano Pigozzi, Massimo Righi, and Claude Dantes are among the cast. ~ Robert Firsching, All Movie Guide
