La 317ème section

Laos, 1954. Just before the end of the Indochina War, the 317th section -- made up of four French soldiers and around forty Laotian fighters -- is ordered to fall back to the plains of Dien Bien Phu, where the French army is stuck. Under the leadership of a rookie second lieutenant and a World War II veteran, the group has to make their way through 150 kilometers of jungle and deal with a harsh environment.
