Decades ago, classmate Lian Xiuying paid 30 yuan in tuition fees for Li Zhiqiang, helping him escape rural poverty. Thirty-five years later, Li has become a corporate tycoon. He learns his benefactor is suffering: her property seized by relatives, her husband abandoned the family, leaving her in debt to raise her daughter alone. Li spares no effort to repay her. He hires lawyers, tracks down witnesses, and helps Lian Xiuying reclaim her flour mill and secure 800 million yuan in compensation, bringing the villains to justice. A small kindness repaid with immense gratitude.
