The Nan Shui Bei Diao is the world’s largest water transfer project, stretching between southern and northern China. Many regions at death’s door depend on this project. But the risks are high, between the damage done to the environment and the impact on displaced populations. This film maps the ever-changing state of a territory redesigned by engineers, where cement reaches beyond the grasslands, rivers leave their beds, deserts become forests, and where voices gradually grow stronger, asking for justice.
