This impassioned documentary chronicles the battle of Chile’s Pehuenche-Mapuche people against the wealthy Spanish-Latin American hydroelectric corporation ENDESA. After hundreds of years of successfully seeing off all invaders – from Incas to conquistadores – these mountain dwellers who live above the Bíobío river are losing their homes, villages and past to a giant hyrdro-electric dam that floods their lands. Despite Chilean laws protecting indigenous rights, their attempts to fight the development have led to arrests, under Pinochet’s anti-terrorist laws, based on testimony from unidentified witnesses.
