Smashing the Spy Ring (1938)

Top U.S. government spy-smasher John Baxter (Ralph Bellamy) does just that as he is aided by Eleanor Dunlap (Fay Wray) and companion federal agent Ted Hall (Regis Toomey) while being highly abetted by top enemy agent Dr. L. B. Carter (Walter Kingsford) and his minions of gang members and henchmen.
