Cop or Hood

A police inspector turns up dead in a prostitute's house, and Divisional Commissioner Stanislas Borovitz (Jean-Paul Belmondo) is sent to find out why. He goes in as Antonio Cerutti, the dead woman's long-lost brother, and finds a town where the cops and the crime bosses work for each other. Georges Lautner puts Belmondo in a fast car outside Musard's place, and then Musard (Georges Géret) is standing naked in a phone booth.
