A model at a high end fashion house is murdered and after her diary is discovered and then goes missing more of the models get murdered by the masked killer. This is one of Mario Bava best films as he combines the thriller genre with the more violent and bloody murder/horror genre. There is a complex plot that is indispersed with the butal killings of several fashion models. The English dubbing in this film is not great, but it is not as bad as many dubbed films. Eva Bartok gives the best performance.
