An innocent man is drawn into a web of espionage when he unwittingly comes into possession of a crucial piece of microfilm in this shadowy, ominous film noir. Fritz Lang’s adaptation of Graham Greene’s novel is filled with unusual touches, beginning with the fact that protagonist Stephen Neale (Ray Milland) has just been released from a mental asylum. To celebrate his return to the real world, he visits a local carnival, only to accidentally receive a “prize” meant for a Nazi agent. When he discovers the error, he turns for help to a detective, whose investigations only make the matter more complicated. Neale soon winds up on the run from both the Nazis and the police, who mistakenly believe him guilty of murder.
