Ma Yuru (Song Dandan) is the director of a police station. Finally, she ushered in the day of retirement and returned to her family to start her old age life, but she found that the trivialities in life were far more complicated and difficult to solve than the accidents and disputes in the station. Ma Yuru has a son and a daughter, Ding Manyi (Xiao Yang) and Ding Ruyi. Ding Manyi had a failed marriage and now raises his son Ding Dang alone. One day, Ding Manyi met the gentle and virtuous Bai Yan (Jiang Yan), and the two gradually fell in love. But at this time, the former father-in-law Cheng Daji (Ni Dahong) suddenly appeared, making the future of Ding Manyi and Bai Yan full of twists and turns. Not only that, Ding Ruyi also met a man named Cheng Gong and fell in love, and this Cheng Gong turned out to be Cheng Daji's nephew. Just when Ma Yuru's family was in a mess, Ding Manyi's long-lost ex-wife Cheng Lu (He Miaomiao) was suddenly revealed to have died.
