 Spotted after he microfilms secret U. S. Navy documents, foreign agent Rattick (Richard Travis) is killed when he tries to make a getaway. Naval Intelligence officer Captain Wright (Selmer Jackson) and Operative Dale (James Griffith as Jim Griffith) are assigned to investigate and determine who is behind the spy syndicate for which Rattick worked. They bring in the services of Agent Tom Norman (Richard Travis in a dual role), who bears a strong resemblence to Rattick.
