Zhang Guilan, a 52-year-old widowed cook, makes a living selling boxed meals. While supplying food to a construction site, she is left with unpaid meal bills by the person in charge, Zhao Dayong, who also falsifies meal expenses and leaves her bearing the blame. She stops paying out of pocket to provide meals and restarts her business with her daughter, Lin Xiaohe, selling through a small window. The two gather evidence to recover the unpaid money, but face a series of troubles, including vicious price-cutting competition, relatives secretly misappropriating goods, and others operating under their name without permission. Through the devastation of torrential rains and the temptation of a major order, the mother and daughter hold firm to their business principles, refusing to expand blindly. Together with their partners, they run their small shop steadily and learn to say no when necessary and stay true to themselves, earning a stable livelihood and the dignity of honest work, one pot of hot meals at a time.
