Cast & Crew
Ace pilot Bob Rogers works for the O. & P. Aerial Express and is engaged to Grace Devine, the sister of his young co-pilot, Jimmy. Bob has a weakness for liquor, however, which is the cause of a bitter quarrel between himself and Grace. Depressed by Grace's recriminations, Bob gets drunk before a flight and relinquishes control of the plane to Jimmy while they are aloft. The inexperienced youth crashes the plane and is severely injured. Bob accepts full responsibility for the accident, even though he will lose his pilot's license as a result. Bob escapes to Tijuana, Mexico, where he meets Kelley, a flyer he knew in the war. Kelley, who has fallen in with a band of crooks, convinces Bob to accept a job piloting a plane. Not until they are in the air does Bob learn that Kelley's gang intends to rob an O. & P. express plane. Refusing to continue, Bob fights the criminals and parachutes from the plane in time to warn the O. & P. pilot of the danger. Soon after, Bob learns that Jimmy is recovering from the accident and then gratefully accepts a mechanic position at O. & P. Bob recognizes Kelley, who is loitering around the field, and grows suspicious of the seeming link between Kelley and Willard, the new manager of O. & P., who has been romancing Grace. Before Bob can alert the others about Kelley's presence, however, he is captured by the gang and locked in the Murphy bed in his apartment. There he overhears them plotting to rob the express plane that Jimmy is to fly. He also hears a telephone call to Willard that confirms the manager's role as the gang's leader. Bob escapes but is too late to intercept Jimmy, who is already being pursued in the air by Kelley and his men. Meanwhile, Willard has taken the unsuspecting Grace to the desert hideout where he is to meet the gang. Bob first notifies the army, then sets out to find Jimmy. He finds Jimmy in the desert, and although the robbery has already taken place, Jimmy is uninjured and Bob leaves him to be picked up by the army. Bob then sneaks up to the gang's hideout and realizes that he will have to be very careful in order to protect Grace. When Kelley steps outside, Bob knocks him unconscious and takes his place as the pilot of the gangsters' plane. Jimmy radios the airport with a description of Willard's plane, and Bob and Grace parachute to safety as the army plane attacks the criminals. Soon after, Bob regains his pilot's license, and also gets a marriage license with Grace.
