Officers Don Burdick and Gil Foley battle crime in a major city in Southern California from the air. They are "chopper" pilots who aid officers in "black-and-white"'s by contributing added surveillance or assisting in chases of suspects. Sometimes they have their own problems to worry about, such as snipers. Mitch was Gil & Don's crusty mechanic, while the two men received their orders from Capt. McKeegan.
