This story tells the tragedy of an ordinary family on the Jialing River in Chongqing that was destroyed due to extramarital affairs. Duan Ting and her husband Wu Yan started a successful freight business from scratch. Duan Ting has always cared about her sister Duan Nan, but she did not expect that Duan Nan and Wu Yan gradually developed feelings and developed an extramarital affair. This triangular relationship eventually led to Duan Nan's four-year-old daughter Beibei accidentally falling to her death. Duan Ting was criminally detained for illegal detention. The originally close sister relationship completely broke down, and the lives of the three people moved towards irreparable tragedy.
Philosophy: An extramarital affair that shouldn't have happened made both the older sister and younger sister lose their minds.
