The murder of a bandit gives a policeman the opportunity to unmask the activities of a spy.

Eddie Constantine stars as a reporter mixed up in the spy world in this routine espionage actioner by first-time director Pierre Grasset. After taking some illicit photos for a new story he is working on, Eddie (Constantine) is coerced into doing a job for the French Secret Service. There is a mole in the French missile sites who is passing on classified information, and Eddie is enlisted as bait to draw the culprit -- or culprits -- out. Along the way, he finds himself running for his life, fighting, and romancing until the final denouement.
