Zhang Xiaohua is a sensible left-behind child abandoned in the mountains by her parents, who favor boys over girls. She depends on her kind and simple-hearted grandmother for survival. With her grandmother's tireless hard work and the support of the villagers, she finally manages to save enough money for school. When she grows up, she is admitted to a top university and even becomes the province's top-scoring student. Her exploitative parents are summoned back to their hometown by her grandmother. Xiaohua and her grandmother initially believe they have returned to celebrate Zhang Xiaohua's university admission, but they never imagine that her greedy parents have sold her to a local tyrant as his concubine.
