Shen Qiulan has been married for nineteen years, during which her father, Shen Dashan, closed his small diner and contributed both money and effort to help her take care of her son. After her grandson is admitted to a prestigious university, her rural mother-in-law, Dong Guixiang, arrives in the city and uses a misunderstanding with the neighbors as an excuse to throw Shen Dashan's bedding into the stairwell. Her husband, Zhou Jianguo, takes his mother's side and forces Shen Qiulan to act as an unpaid maid. Shen Qiulan acts submissively on the surface while secretly selling her pre-marital property. At the housewarming banquet, the truth about her husband and mother-in-law pretending to be wealthy for years, extorting money under the guise of treating illnesses, concealing assets, and committing extramarital affairs is exposed one after another. Even when the two record videos playing the victim, they are pierced through by the preserved complete evidence. After the divorce, Shen Qiulan takes her father and son and begins a peaceful life.
