World War I British aviator Jack Bardell (John Garrick) is discharged from the service after a suspicious aircraft crash that his fellow pilots believe show that he was a coward in the face of the enemy.

He is left temporarily paralyzed from the waist down, and enlists the aid of his mechanic Tom Berry (Billy Bevan) to rebuild a wrecked fighter aircraft.

Bardell recuperates to the extent that he is able to fly again, redeeming himself during a German Zeppelin attack over London, bringing down one of the airships.

One of the most impressive aspects of the film was Special Effects Coordinator Ralph Hammeras creating a large-scale miniature of the city of London in the Fox Studios airfield hangar built for Hell's Angels (1930).

Mordaunt Hall of The New York Times praised the film, noting: "A melodrama of the skies which has not been equaled in its adroit handling, its competent acting, its authentic atmospheric effects, or the tonal quality of the voices of the participants was launched last night by William Fox at the Gaiety Theatre.
