Deep in debt to the tune of 80,000, Ding Wenjing has nowhere to go and takes her daughter to live in a dilapidated house with a leaking roof. To buy her child two meat buns, she relies on her exceptional eye for value and business acumen, starting with collecting discarded items and gradually building a market for her goods. Jealous rivals scheme to force down her prices, steal her customers, and cut off her supplies, but she repeatedly turns the tables against all odds. With relatives plotting against her and debt weighing heavily on her shoulders, she pays off what she owes while overcoming one obstacle after another, finally clearing the entire 80,000 debt. Those who once looked down on her poverty and feared she would become a burden eventually realize that the woman they drove out of the family home has become someone far beyond their reach. But when a corporate platform arrives with an acquisition offer and aggressive undercutting, she faces a choice: sell everything or hold on to the path she has carved out for herself.
