The film was released as Deadlier Than the Male in the United States and as Twelve Hours to Live in the UK.

[2] It is a dark tale of a young and pretty femme fatale who ruins the life of a man and kills his best friend.

In Les Halles, in the heart of Paris, the long-divorced André Chatelin, an honest and respected man who runs a successful restaurant, is visited by an unknown young woman.

And she starts stealing money to support her mother, who is not dead but an ex-prostitute who is now a hopeless drug addict in a sordid hotel.

A grieving André identifies the body, leaving his telephone number with the police, who ring him to ask if he knows the woman seen in Gérard's car.
