Disgraced Secretary Ku has been banished from the Party - it has been officially proved he does not have a fish-shaped birthmark on his bottom and is therefore not the son of a revolutionary martyr, but the issue of a river pirate and a prostitute. Mocked by the citizens of Milltown, Secretary Ku leaves the shore for a new life among the boat people on a fleet of industrial barges. Refusing to renounce his high status, he maintains a distance - with Dongliang, his teenage son - from the gossipy lowlifes who surround him.
One day a feral little girl, Huixian, arrives looking for her mother, who has jumped to her death in the river. The boat people, and especially Dongliang, take her to their hearts. But Huixian sows conflict wherever she goes, and soon Dongliang is in the grip of an obsession for her. He takes on Life, Fate and the Party in the only way he knows . . .
