Plot

Lee Graham (Bruce Bennett) and Johnny Davis (Frank Albertson) are U.S. government agents, aided by Ann Carter (Leslie Brooks), assigned to prevent German spies involved in a telephone-tapping scheme from infiltrating a California war-defense plant. To help them in their cause Lee invents an ingenious word-scrambler which leads to the round-up of the German spies.—Les Adams <longhorn1939@suddenlink.net>
