After a jeweler hires a private detective to help him find $50,000 missing from his company, he is murdered while attending a society party; and the private eye, aided by his comely secretary, vies with a bumbling police detective to find the murderer among several suspects, including the dead man's daughter, her current husband, her former husband, and an ex-convict.

An action-filled film with outlaws-of-the-clouds at war with the men of the U. S. Flying Service. A young pilot, Nick Ferris, fights to track down a dangerous gang of smugglers and clear his name of an undeserved stigma.
