French Guiana is 90 percent forest, one of the rainiest places on earth, and home to the 3rd Infantry Regiment of the French Foreign Legion since 1973. This film follows recruits through CEFE, the Legion's jungle combat school, where roughly 40 soldiers start a course and most fail to finish. There are no sanitary facilities, food is rationed, and daily injuries, dehydration, and exhaustion thin the ranks before instructors even factor in obedience drills that punish the smallest mistakes. Cameras track a legionnaire and a female officer candidate as the course pushes them toward physical collapse, alongside footage of the regiment's actual missions: Harpie, in which soldiers move through the rainforest before dawn hunting armed, mafia-organized illegal gold prospectors, and Titan, guarding the Kourou spaceport since 2008. The documentary gets access most outsiders never do, showing the mud, the rain, and the instructors' unbending discipline up close rather than describing it secondhand. It plays as much as a portrait of institutional cruelty as of endurance.
