At Li Jianqiang's 52nd birthday banquet, Wang Mei, his ex-wife who had vanished for twenty years, suddenly returned with their daughter Xiao Ya, claiming that her departure back then was to force him to succeed, and wanting to reclaim this home as the original wife. However, she had stolen the twenty thousand yuan for their daughter's medical treatment back then, causing their five-year-old biological daughter to pass away from illness, and also swept away the grandmother's life-saving money to elope with the scammer Chen Dafa. Li Jianqiang had long since registered his marriage with Liu Ying, who had always cared for his parents and accompanied him in starting his business, building a happy family. Faced with Wang Mei's entanglements, disruption, and scheming, Li Jianqiang produced evidence and called the police. After being exposed, Wang Mei was reduced to a sanitation worker, and Chen Dafa was also arrested for fraud. In the end, Wang Mei was abandoned by everyone.
