In 1997, Zhang Chengxi (played by Zheng Jiaying), who had just passed the examination to become a correctional officer, received a call for help from his sister. His stepfather had just attempted to rape her but failed. After years of repressing his anger, Xi rushed to his stepfather and had a conflict with him. When he tried to resist his stepfather's fightback, he accidentally knocked him out with a wrench. Xi left in panic and was arrested by the police the next day on charges of murdering his stepfather. It was his cousin Tong Lip-yin (played by Guo Jinan) who gave the key evidence in court. Xi was convicted and imprisoned for 13 years. In 2007, Xi was released from prison. For ten years, he had been waiting to find out a fact: why did Tong Lip-yin make a false confession? Today, Tong Lip-yin is the boss of the Zhiyanxing Company. In the eyes of the world, he is a righteous image who strictly pursues the truth and is not afraid of power. However, Xi's criminal record and bad temper scare all those who are close to him. The road to revealing Tong Lip-yin's true face is long and difficult, and the contest between the two men officially begins.
