Aviator Lt. Al Willis returns home from combat duty to find his father, cotton farmer Jim Willis, in jail for the murder of neighbor Jud Blair, a crime actually committed by dance hall owner Melvin Parker. Al purchases an airplane with a fellow veteran and they embark on a barnstorming tour, all the while looking for clues to find the real murderer. At a bullfight in Mexico, Melvin's sweetheart, Sybil, becomes infatuated with Al and betrays her lover. Melvin flees in an automobile, but Al flies after him, leaps from his airplane into the speeding car, and overcomes his adversary. Jim is set free and Al weds their late neighbor's daughter, Anne Blair, in an airplane far above the clouds.
