Filmed in English, this Italian mystery thriller/melodrama explores the murder of a doctor's wife. The doctor himself (Jean Morel) has long since taken up with a mistress. His wife begged out of engagements as an asthmatic, all the while actually entertaining herself with her part-time job as a stripper. Did the doctor kill her? After all, he took out a large life-insurance policy on his wife. One highlight of this film is the effective use of its San Francisco setting. Another is its gas-chamber sequence, filmed in San Quentin's actual gas chamber.
