Leon Ames returns as Major Waring, together with much of his crew from the movie Cipher Bureau, including Charlotte Wynters as Helen Lane; there’s even a mention of Waring’s brother, who had a prominent role in the prior film. Indeed, this sequel opens with Waring and Lane about to get married, when they are interrupted by an urgent request for the decoding of a message. Waring and the gang soon uncover evidence of a band of foreign spies after secrets related to the Panama Canal, but their efforts to put the bad guys out of business are undermined by their opponents’ knowledge of their every move. Could there be a traitor in their midst? An efficient little programmer.

  Mildly recommended. Otto judiciously thinks this movie is OK, but not great.

Movie 141 for 2021.
