Shanghai in the early 1990s. One day, Guan Hongying is found dead. Chief inspector Chen Cao, along with his subordinate, Yu, start to investigate this murder case and find that this young woman lived a double life. On one side, Guan Hongying was a member of
Communist Party and a popular public figure. On the other, she lived a “degenerate” lifestyle, away from the eyes of the public. This secret lifestyle brings the case into the public's attention, once this young woman dies. During the investigation, Chen and Yu discover that the number one suspect, Wu Xiaoming, is the son of Wu Bing, a high-ranking Party cadre. Wu and his father put the detectives under a huge pressure to avoid investigating, but with the help of Ling's father, Chen succeeds to save himself from the pressure and sends Wu to the court. Chen and Yu struggle to discover his motive to kill Guan. Eventually, Chen discovers his motive: Guan had been blackmailing Wu to make him leave his wife. Wu did not want Guan to jeopardize his political career. As a result, he murdered her. Chen brings these facts to the attention of his superiors. == Characters ==
