A luxury cruise boat motors up the Yangtze, navigating the mythic waterway known in China simply as "The River." In the biggest engineering endeavour since the Great Wall, China has set out to harness the Yangtze with the world's largest mega-dam.

Meanwhile at the river's edge Yu Shui says goodbye to her family and turns to face the future. From their small patch of land, her parents watch the young woman walk away, her belongings clutched in a plastic shopping bag. The waters are rising.

The Three Gorges Dam, gargantuan and hotly contested symbol of the Chinese economic miracle, provides the epic and unsettling backdrop for Up the Yangtze, a dramatic and disquieting feature documentary on life inside the 21st century Chinese dream.
