The Pehuenche-Mapuche people live above the Bíobío river in Chile and have fought off all invaders who tried to cross it, from the Incas to the Spanish conquistadors. But they have never battled an enemy like Endesa, the giant Spanish hydro-electric company which has dammed the Bíobío, flooding the Ralco valley and forcing the ‘exchange’ of whole villages to much higher ground. Despite protections for indigenous people enshrined in the Chilean constitution, the government has shown little motivation to take their side against the wealthy multinational. Protestors against the company have found themselves arrested under Pinochet’s anti-terrorist laws, facing anonymous witnesses whose identities are concealed from even the court. Reminiscent of Michael Moore’s "Roger & Me," Mayol’s futile efforts to interview anyone from Endesa are tragicomic as they find new excuses each time he calls.
