Synopsis by Hal Erickson
No sooner had Columbia called it quits with the "Blondie" series than the studio launched a new group of "B"-pictures, based on the popular radio series David Harding, Counterspy. Third-billed Howard St. John plays Harding, with actor/director Fred Sears co-starring as Harding's assistant Peters. Most of the film is carried by Willard Parker as Jerry Baldwin, a navy commander assigned to root out saboteurs in a torpedo factory. Falling in love with Betty Iverson (Audrey Long), the widow of his murdered predecessor, Baldwin is aghast to learn that Betty may be an enemy agent. There's action aplenty as the film rushes to its pyrotechnic conclusion.
