At the United States Edwards Air Force Base Flight Test School, instructor wartime veteran, Capt. Steve Morley (Rex Reason) resents "playing nursemaid to a bunch of glory jockeys." The new class includes Kurt Weber (Giuseppe Addobbati), who flew for Germany during World War II; Maj. Mike Geron (Buck Class); show-off Capt. Murphy (Lee Farr); Lt. Jimmy Erskine (Robert Dix) and Lt. Bob Kiley (Robert Conrad).[Note 1]

Steve meets his sweetheart, Susan Blair (Audrey Dalton), a secretary for Lt. Col. Spalding (Dick Fora). Dissatisfied with his role, his pupils continue to have problems as he tries to stress that discipline is important. Both Susan and Steve's fellow flight instructors caution him that he is too harsh. Asking again for a transfer, Steve is denied.

On a training mission the next day, Murphy flies dangerously and is expelled for his irresponsible behaviour. Fellow students, are certain that Steve is to blame. Later Steve takes Mike up, but the engine flames out and Mike passes out. Steve seizes the controls and lands the aircraft safely, saving them both and the aircraft. Finally, his students accept Steve, realizing he is just trying to help them achieve their goal of becoming test pilots.
