In the summer of 2008, a group of young French paratroopers on their first mission in Afghanistan find themselves trapped in the Uzbin Valley. What begins as a routine patrol quickly descends into a harrowing, life-altering ordeal as they are ambushed by Taliban fighters. Through the personal accounts of the survivors, the film explores the profound psychological impact of the battle, the loss of innocence, and the enduring bond of a brotherhood forged in the crucible of war.
