In Washington D.C., Mr. Jones (
Rafael Storm) receives a telegram from Los Angeles asking him to secure rights to a newly designed aircraft from inventor F. S. Reynolds (
William Humphrey). Later that day, Cardigan (
Robert Frazer), a gangster, lies to Jones that Reynolds is not really interested in his offer. Cardigan tries unsuccessfully to buy the aircraft and its plans from Reynolds. Test pilot Hal Foster (
Richard Talmadge) and his girl friend, Reynolds' daughter Jean (
Gertrude Messinger), arrive and Hal throws Cardigan out. Afterwards, Hal test flies the new aircraft and as he and Reynolds discuss its problems, Cardigan's henchmen arrive and steal the aircraft and the plans. Hal follows their car on his motorcycle and Berty ( Eddie Davis), Hal's goofy friend, follows in a car. Hal catches up with the henchmen and they engage in a brawl. After Berty arrives, he and Hal go to Cardigan's Chinatown home, but Cardigan's Chinese butler refuses them admittance. As Cardigan phones Jones to let him know that the aircraft is secure at an abandoned desert airfield, Hal and Berty break into his headquarters and overhear the location of the aircraft. Hal is captured, but later Berty, disguised as a Chinese servant, releases Hal and they use one of Reynolds' aircraft to fly to the desert airstrip. A government agent, who is also a pilot, arrives at Reynolds' headquarters, searching for Cardigan, and Jean guides him to the secret airfield. Cardigan's henchmen see Hal's approaching aircraft and try to chase him down, but he jumps from his aircraft into theirs and upon subduing them, lands the aircraft. Jean and the agent arrive. The agent arrests Cardigan and his men, and Jean and Hal embrace. ==Cast==
