A plodding, unimaginative spy film made even worse by Reed "Racket Squad" Hadley's pompous, pseudo-documentary narration. Only Leo G. Carroll and Gene Lockhart deliver interesting performances.

The attempt at documentary-style realism leads to some pretty nice location photography, but there's very little to recommend here. The story is largely uninteresting, the acting is unremarkable and the pacing is deathly slow. Factor in the overblown voice-over and the constant reminders of how great the FBI is and the whole thing starts to resemble something between a propaganda piece and a job recruitment advert.

A very dry affair, with a full 8 minutes of introductory background and very little drama throughout. Some of the stuff that reveals the techniques of the FBI are mildly interesting, but mostly the film just plods along until the climax, which is exciting but not enough to salvage the rest of it. Most of the leads are rather flat, but Lloyd Nolan is fun to watch as the agent, and Lydia St. Clair is an amusing Rosa Klebb type. Otherwise, a pretty dull FBI puff piece.

A documentary-style noir-of-sorts that is expectedly patriotic and heavy-handed. It moves at such a slow pace, and inadvertently portrays the dullness of a typical FBI agent's job. However, due to the use of real surveillance footage as part of the telling of this 'real' story, and as an insight into the mindset of post-war America, it's possibly worth a look.
