A radio engineer ends up unknowingly working for Axis spies who are using a stolen new shortwave transmitter to supply information to a Japanese sub targeting U.S. ships. Richard Arlen is fine as the lead, a man who has lost his job and takes what he can, and Wendy Barrie has a good role as the government agent assigned to cover his actions and track down his employers. The enemy agents are suitably despicable.

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

Movie 137 for 2021.
