A young pilot, fresh out of training, is called to join a Flight while they wait for the call to scramble. Throughout a single day, he witnesses the skies of southern England filled with deadly dog fights, and after every exhausting battle the men return to their dispersal hut, only to find another of their number missing. Unwilling to surrender, the pilot and his comrades unite to take to the skies once more, determined to defend not only the airfield, but their entire country.
In autumn 1944, during the Liberation of Brittany, writer Louis Guilloux worked as an interpreter for the American army. He was a privileged witness to some little-known dramatic aspects of the Liberation: the rapes and murders committed by GIs on French civilians. He also discovered the racism of American military justice. This experience haunted the novelist for thirty years. In 1976, he recounted it in a short novel, "Ok, Joe", which went unnoticed. This film compares his account with the memories of the last witnesses to these forgotten crimes and their punishments.
