In 1943, Captain Buzz Rickson (Steve McQueen) is an arrogant pilot in command of a Boeing B-17 Flying Fortress bomber nicknamed ''The Body''. While stationed in UK during the Second World War, one of the bombing missions is aborted because clouds obscure all potential targets, but Rickson ignores the order to turn around and dives under the clouds. He completes the mission, at the cost of one of the bombers in his squadron and its entire crew. Rickson revels in the fighting and destruction; when he is assigned to drop propaganda leaflets on a later mission, he makes his displeasure felt by buzzing the airfield. His commanding officer tolerates his repeated insubordination because he is the best pilot in the bomber group. Even so, when he asks the flight surgeon his opinion, the latter is uncertain whether Rickson is a hero or a psychopath. However Rickson's crew, especially his co-pilot, First Lieutenant Ed Bolland (Robert Wagner), trust his great flying skill.
