The play begins with Xiao Jian (Yu Yi), the director of the Economic Investigation Department, investigating a bizarre car accident. Through an in-depth investigation of the illegal stock market manipulation of the "Haixiang Group", the play triggers an exploration of the past entrepreneurial history of the mysterious business tycoon Xu Feng (Guo Jingfei). The loss of key witnesses, the pressure of public opinion, the mastermind of the death, and the revelation of Xu Feng's identity, all point directly to the financial case 20 years ago, which later involved a larger transnational money laundering group. Xiao Jian accidentally obtained Xu Feng's hidden diary and discovered another identity that Xu Feng had been hiding. Faced with a strong enemy and pressure from behind, Xiao Jian, who was relentless in his pursuit, broke through many difficulties with a sense of responsibility and mission, and finally wiped out the huge financial crime organization.
