Shen Yuqin has retirement savings, but outwardly claims to only have 200,000, which provokes dissatisfaction from her daughter-in-law Tang Wanning. After being rejected when trying to borrow money for her younger brother, Tang Wanning kicks Shen Yuqin out of the house on a rainy night, and conspires with her brother to secretly photograph the property deed and forge a signature in an attempt to mortgage the property. Son Lu Chengze collects evidence and hires a lawyer to stop it, ultimately leading to a divorce. The Tang family harbors greed once again taking advantage of old house redevelopment, and Shen Yuqin sees through the scam with the help of a lawyer and the community. Holding no old grudges but firmly maintaining her bottom line, she joins a senior mutual aid group to help others. Two years later, she happily moves into a new home, realizing that holding onto oneself is the true foundation of old age.
