A journalist and a police commissioner join forces to smash a white slavery network operating in the Middle East. The cabaret run by Clovis where Dalida sings is quickly spotted, as is a marriage agency run by Madame Irma, offering semblance of guarantees. Clues without proof. The journalist's fiancée agrees to play the game set up by the superintendent. The network is dismantled.

The mysterious death of a well-known criminal sparks an investigation into national security.

Set during World War II in France, the story begins when a resistance fighter is given shelter in an asylum by a friend who manages the institution. Soon after, the manager is arrested by the Gestapo, which gets the resistance fighter involved. He finds the informer who set his friend up and kills him. But then no one will believe his story about the informer and he becomes desperate enough to start losing his own mental balance. A young doctor and the daughter of one of the inmates help him keep it together, but he knows he cannot continue like this for long.
