The story features Jenny, played by Clouzot's long-time companion Suzy Delair (still alive, I gather, at the splendid age of 100), who is a talented and sexy singer and a performer ambitious to get on in the world. She's married to Martineau (Bernard Blier), a quiet pianist who is driven to jealousy by her flirtatious ways. She cares for him, but is determined not to allow him to dominate her or wreck her prospects of fame.
A wealthy old lecher called Brignon takes a fancy to Jenny, in a scenario which, unfortunately, remains topical to this day. Martineau begs Jenny not to agree to see Brignon again, but she reckons she can take care of herself. He constructs an alibi at a theatre while following her to the place where he reckons she is due to meet Brignon, only to find that Brignon is dead. It seems clear that Jenny has killed him, and Martineau can't resist the temptation to interfere with the crime scene. Meanwhile, Jenny's friend Dora, a photographer who used to take nude pictures of Brignon's conquests, tries to help her out.
Louis Jouvet plays the detective who is soon on the trail. His performance is highly enjoyable, and overall this is a film which has earned the critics' admiration over the years. It has a depth, as well as a number of very pleasing touches, and it's probably one of those films that merits at least a second viewing to appreciate everything. I didn't find it quite as impressive as Le Corbeau,a film Clouzot made a few years earlier, or Les Diaboliques, which most people regard as his masterpiece, but it's definitely worth seeking out.
