Synopsis by Hal Erickson
This sequel to Grand National's 1938 actioner Cipher Bureau once again stars Leon Ames as bureau head Major Philip Waring. In case you're wondering, the Cipher Bureau is a government agency in charge of decoding enemy messages. Teamed with agent Helen Lane (Charlotte Wynters), Major Waring is dispatched to the Panama Canal. Here the two operatives discover that an Oriental spy ring (no nationalities, please: this is still 1939) is stealing vital secrets concerning the Canal. Almost as dangerous as the spies is Abner Biberman in the role of a turncoat bureau agent. The very brief "Cipher Bureau" series was created by Arthur Hoerl and Monroe Sheff.
