1943. Best friends, US Army Air Force bomber pilots Majors Gale "Buck" Cleven and John "Bucky" Egan have been posted to the 100th Bomb Group in England, flying B-17 bombers. Cleven will be a squadron commander, Egan the group's air exec. The 100th Bomb Group will be part of the allied air offensive against Germany and nothing can prepare Cleven and Egan for what lies ahead.—grantss
