Sette orchidee macchiate di rosso

A serial-killer is attacking women in Italy, leaving a silver moon near their corpses. While traveling to Paris by train with her fiancé, the famous designer Mario Gerosa (Antonio Sabàto), Giulia Torresi (Uschi Glass) is assaulted by the serial-killer in her cabin. Police Inspector Vismara (Pier Paolo Capponi) decides to hide that Giulia has survived to protect her. Mario decides to investigate the victims and finds that six women had been in the hotel Giulia owned in the past. They travel expecting to save the women that have not been attacked before the killer finds them.

"Sette orchidee macchiate di rosso", a.k.a. "Seven Blood-Stained Orchids", is a thriller that could have been better. The plot is not engaging but there are violent murders. Indicated only for fans of giallo. My vote is six.
