Plot synopsis: Shenzhen, China, the present day. Nineteen-year-old Wang Baihe is a migrant worker from a village in Shaanxi province. She has a baby son from a one-night stand with a man from Hong Kong and a small income from making Chinese decorative knots at home. Her dream is to open a noodle restaurant and “make lots of money and become a city person” but she finds it difficult to find regular employment because of her baby boy. Her story emerges through interviews with journalist Liu Nan, who is writing a book about her. When Baihe discovers her son has congenital heart disease, she tries desperate ways to raise the RMB80,000 (US$12,000) for the operation, helped by her friend and fellow migrant worker Hu Jinling.
