The elderly mother of the Li family suffered from Alzheimer's disease, initially cared for primarily by the eldest daughter-in-law, Chen Feng. One day, Chen Feng went out to do her hair, leaving the confused mother alone at home. A fire accidentally broke out in the house, and the mother was trapped inside. Fortunately, the younger sister, Li Changle, discovered it in time and called for rescue, saving the mother and exposing the deep-seated conflicts behind eldercare. The siblings decided to take turns bringing their mother home to fulfill their filial duties, but caring for a demented elderly person proved far more difficult than imagined. Various households encountered successive crises; the old lady frequently caused trouble and wandered off, leaving the children physically and mentally exhausted, and finally understanding the difficulty of Chen Feng's three years of care. After much deliberation, the family sent the old lady to a professional elderly care institution.
