In June 1944, Johannes Börner is 19 years and Léon Gautier 21. These two elite soldiers will take part in the battle of Normandy in the frontline, each convinced to fight for the good cause. One will experience the thrill of victory, the other the humiliation of defeat and prison camps. Seventy years later, they live in the same place, Ouistreham, a seaside resort of the Calvados where Léon Gautier landed among the 177 French of the mythical Commando Kieffer. Johannes Börner, him, married a Norman and became French in 1956. They are friends and reflect together their experience so that humanity never again know the horror of World War II.
