Durante il culmine della Battaglia d'Inghilterra, uno stormo di esausti piloti Spitfire combatte fino all'ultimo uomo in difesa del proprio paese.

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.
