The story takes place in the bustling metropolis of Beijing. Mother Zheng (Pan Hong)'s husband died early, and she raised her three daughters, Zheng Nannan (Zuo Xiaoqing), Zheng Tingting (Gao Lu) and Zheng Duoduo (Liu Yun), alone. Seeing that all three children have found their ideal husbands and are living a happy life, Mother Zheng feels that her lifelong wish has been fulfilled and that she lives a fulfilling and satisfying life. By chance, Mother Zheng discovered that her deceased husband might have a large sum of private money. This discovery overturned Mother Zheng's world. She warned her three daughters to keep an eye on their husbands financially, otherwise there would be endless troubles. In this way, with the involvement of Mother Zheng, the three families launched a vigorous search for private money, but the result was counterproductive, causing cracks in the three families.
