During WWII, in France, Jean Picard is a criminal who is about to be executed via the guillotine, but an air raid interrupts it and allows him to escape. Inspector Bonet tracks him down and brings him back. But along the way, they hear that a railway bridge vital to the Germans has been destroyed, supposedly by allied agents. The Germans take 100 Frenchmen and are threatening to execute them unless the saboteurs come forward. Picard who would rather die at the hands of the firing squad as oppose to the guillotine, offers to go to the Germans and say that he is the saboteur. Bonet accepts and so they go the village near where the bridge was to learn all that they can so that Picard can convince the Germans that he is the saboteur. While there Picard, a womanizer, meets a young woman and falls in love with her.
