An environmental movement takes root when a new environmental law is passed, and for the first time in China’s history, ordinary citizens have the democratic right to speak out and take part in government decisions. Activists test this new freedom and save a river. The movement they trigger has the potential to transform China. The film, seen through the eyes of activists, farmers and journalists, follows an extraordinary campaign to stop a huge dam project on the Upper Yangtze River in southwestern China. It features astonishing archival footage never seen outside China, and includes interviews with government insiders and witnesses, who recall the history of Chairman Mao’s campaigns to conquer nature in the name of progress. Directed and produced by Gary Marcuse.
