It is 1940, prior to the American entry into World War II. After a simulated air raid against Los Angeles involving eighteen U.S. Army Air Corps Boeing B-17 Flying Fortress bombers, one of them goes down in the desert on its way back to base. Mysteriously, the dead body of a woman is found in the wreck. The pilot, Second Lieutenant Jefferson Young III, is accused of having an unauthorized civilian passenger on board and charged accordingly for disobeying orders. Before the court martial renders a verdict, they review Jeff's military background and history.
