Synopsis by Hans J. Wollstein
The then-popular government agents, the so-called G-Men, took to the air in this standard 15-chapter serial thriller courtesy of Columbia Pictures. Hal Andrews, known under the colorful alias "The Black Falcon," and his two fellow operatives, Bart Davis (Robert Fiske) and John Cummings (James Craig), track down the villain who killed one of their colleagues. The murderer proves to be the head of a gang of saboteurs who are planning a strike on the country's air defense. Lorna Gray, later known as Adrian Booth, lent a bit of feminine appeal to the otherwise decidedly masculine goings-on.
