Steve Harmas, American newspaper correspondent, comes after World War II to London, a place where he has had good memories, on official business, and finds that his girlfriend staying there has committed suicide under mysterious circumstances in her apartment.

The police conclude that it is suicide, but Harmas, knowing Netta not to be that type, thinks it is murder, and goes about trying to solve the case.

Tracing Netta's activities, Harmas soon comes across a friend of the deceased working in Bradley's bar, a tough guy and a goon.

Bradley sends goons to beat Harmas black and blue and threaten him to leave Great Britain.
