Three government aviators, Hal Andrews (Robert Paige), Bart Davis (Richard Fiske) and John Cummings (James Craig) called the "Flying G-Men", one of whom is disguised as "The Black Falcon" (Robert Paige), fight to protect the US and its allies from an enemy spy ring and to avenge the death of the fourth Flying G-Man, Charles Bronson (Stanley Brown).
Bronson was killed when he attempted to stop enemy agents from stealing the new McKay military aircraft, designed by Billy McKay (Sammy McKim). The Junior Air Defenders are also enlisted to help the Flying G-Men. A plot to infiltrate all military factories and airports is discovered but the spy chief called "The Professor"(Forbes Murray) is unknown. Suspecting Marvin Brewster, the owner of a local airport, is The Professor. The G-Men find that he has kidnapped Babs McKay (Lorna Gray), but they follow him to the spy hideout to capture Brewster and rescue Babs.
