The centrepiece of this March of Time film is the dramatised sequence showing the FBI infiltration of a group of American Nazis, whose espionage and sabotage operations are run from the backroom of a local restaurant. The film’s message - that the FBI is more than a match for German spies - is reinforced by the focus on new techniques such as covert filming and forensic evidence analysis, helped by an army of administrative staff working alongside the Bureau’s 4,500 special agents.
