56-year-old retired female worker Li Xiuzhen is jointly forced to move out by her son Zhang Wei and daughter-in-law Wang Yaqin, who demand she sell her only home to buy the young couple a new house. Pushed past her limit, Li Xiuzhen turns the tables, signs the house-selling contract, and leaves with the house proceeds, opening a tailor shop in the old street to stand on her own feet. Her son repents and chases after his mother, while the daughter-in-law's family schemes to the end only to end up empty-handed. The awakening and counter-attack of an ordinary mother.
