Two mega-dams anchor this film's case against hydropower's clean-energy reputation: Belo Monte on Brazil's Xingu River in the Amazon, and Ilisu on the Tigris in southeastern Turkey. The film travels to both sites, showing the forests and archaeological remains of ancient Mesopotamia that would be flooded, and talking to the people slated for displacement, communities numbering in the thousands who have organized resistance rather than relocation. Engineers and campaigners lay out the argument that reservoirs behind large dams, especially in tropical zones, can generate more greenhouse gas from rotting submerged vegetation than a coal plant producing the same power, undercutting the industry's climate pitch. The film also tracks how these projects get approved, describing legal maneuvers and permitting shortcuts used to push construction through over local objection. Rather than treating Belo Monte and Ilisu as isolated controversies, it presents them as a pattern repeating wherever governments pursue large-scale hydropower, with the same tradeoffs of lost land, lost heritage, and disputed climate math.
