Before giving birth, Zhao Juan and her husband, Lin Qiang, agreed that she would stay at a high-end postpartum care center. However, her mother-in-law, Zhang Guilan, rejected the plan and took the 100,000 yuan set aside for the expenses. Clinging to outdated beliefs, Zhang Guilan forbids Zhao Juan from washing her hair, serves her nothing but watery meals, forces her to mop the floor just one week after giving birth, and even secretly feeds the newborn traditional home remedies. Zhao Juan advocates scientific childcare but is met with criticism, while Lin Qiang tries to keep the peace between his wife and mother, pushing his marriage to the breaking point. When their daughter finally suffers from improper care, the long-suffering Zhao Juan explodes. She confronts Lin Qiang and firmly defends her daughter's health and her own boundaries, setting off a family battle over postpartum care.
