When 39-year-old Shen Qiuning returns home, she discovers that her 68-year-old mother has fallen and been left paralyzed in the apartment corridor for two hours. Yet her father, older brother, and sister-in-law all lie, each claiming to have just arrived home and known nothing about it. Following layers of evidence, including surveillance footage, access records, withdrawn messages, and house-sale budgets, she uncovers the cruel truth: although no one in the family seems openly malicious, everyone shirks responsibility while secretly calculating how to profit from her mother's property and retirement. In the end, the daughter breaks the cycle of always stepping in to clean up everyone's mess, while her elderly mother escapes the fate others have arranged for her and personally reclaims her property and the right to live her remaining years on her own terms.
