The region of Danjiangkou Reservoir in Henan is undergoing the migration of 400,000 people to cope with the South-to-North water diversion project. Seventy eight affected fishing households on one of the small islands in the area are told to move onshore, 200 kilometres away from their homes. They protest in vain and fail to get their way, under government pressure. Meanwhile, a thunderstorm hits the island and destroys all their mariculture rafts. The efforts of generations of self-sufficient fishing families are now gone.
