On the Pacific island of Bougainville, landowners rise up against Rio Tinto's Panguna copper mine, one of the largest in the world, after decades of environmental destruction and profits flowing overseas. When Papua New Guinea sends in troops and imposes a blockade, cutting off fuel, medicine, and outside contact, the rebels retreat into the mountains and improvise. Filmmaker Dom Rotheroe embeds with the Bougainville Revolutionary Army as they run trucks and generators on refined coconut oil, forge bullets from scrap metal, and build a functioning resistance movement almost entirely from what the jungle provides. Interviews with fighters and commanders, including Francis Ona, lay out the grievances behind the uprising and the improvised engineering that sustains it under a naval and air blockade lasting years. The film follows the guerrillas through the bush, into hidden workshops, and to the negotiating table, tracking a conflict that killed thousands largely outside international attention. It ends as a rare case of an indigenous population outlasting a multinational mining operation and the government backing it.
