Journalist Karl Penhaul spends ten days embedded with a fighting unit of Colombia's FARC guerrillas, living alongside them in jungle camps to find out what keeps the insurgency going after decades of war. The film follows fighters through daily routines, marches, and weapons drills, with commanders and rank-and-file guerrillas explaining in their own words why they joined, what they believe they are fighting for, and how they see the Colombian government and military. Penhaul, reporting as an outsider granted rare access, presses them on tactics, recruitment, and the group's ties to the drug trade that funds it, without a scripted narrator smoothing over the contradictions in their answers. The footage stays close to the ground: cooking fires, hammocks strung between trees, young recruits handling rifles, and long stretches of waiting that make up most of guerrilla life. The result is a direct look at an armed movement usually described only from the outside, told through the people who carry its rifles.
