Plot Summary
When a top American scientist working on a shortwave transmitter prototype is murdered by Nazi agents, the FBI suspects a spy ring is leaking shipping routes to enemy submarines. To catch the culprits, they orchestrate a covert operation: firing top radio engineers and tracking who gets recruited by the enemy.
Lewis J. “Lee” Deerhold (Richard Arlen), one such engineer, is approached by suspicious figures and drawn into a web of intrigue. With help from Ann Patterson (Wendy Barrie), a government agent posing as a secretary, Deerhold uncovers a plot to transmit secret convoy data to a Japanese submarine lurking offshore. The climax involves a race against time to stop the transmission and prevent a deadly ambush.
