A network of spies affects the lives of people in and out of the organization in this espionage drama. Dominique is the neglected wife of a spy who tracks him down at a Paris antique shop. Finding him with a female spy, the enraged wife shoots both of them. Dominique hides out on a boat while the police investigate the murders, and international spies scramble to recover some missing microfilm. Helen is the spy boss who orders a hit man to go after Dominique.
