When Sunflower, a young city girl, moves to the countryside, she grows to love the reed marsh lands - the endlessly flowing river, the friendly buffalo with their strong backs and shiny, round heads, the sky that stretches on and on in its vastness. However, the days are long, and the little girl is lonely. Then she meets Bronze, who, unable to speak, is ostracized by the other village boys. Soon the pair are inseparable, and when Bronze's family agree to take Sunflower in, it seems that fate has brought him the sister he has always longed for. But life in Damaidi is hard, and Bronze's family can barely afford to feed themselves. Can the little city girl stay here, in this place where she has finally found happiness?

A classic, heartwarming tale set to the backdrop of the Chinese cultural revolution.
