In 1954, the Indochina War begins to come to a close following France’s defeat by the Viet Minh at the deadly Battle of Dîen Bîen Phû. French forces are in full retreat and risk being overrun at every turn — including the 317th Platoon, a unit of French soldiers and Laotian allies who are led by the idealistic but inexperienced sous-lieutenant Torrens and adjutant Willsdorf, a former soldier in the German Wehrmacht during WWII. Their survival depends on completing a trek through the dense, jungle-laden, expanse of enemy territory that stands between them and the safety of the nearest French outpost.
