During the trial, Jiang Chen was ridiculed by the opposing lawyer Zhang Wei in public as "useless" and fell into a desperate situation. But he calmly opened the file and found an overlooked date suspicion, and then collaborated with his assistant Lin Wei to conduct a secret investigation. With the betrayal of witness Chen Guodong, the secret assistance of clerk Li Fang, and the discovery and handover of the recording by newcomer Zhao Mingliang, Jiang Chen completely exposed the truth about Zhang Wei's forged evidence, forcing Zhang Wei to kneel down and beg for mercy on the spot. This battle not only won the case, but also made Jiang Chen famous, and also started a new journey to pursue more secret cases side by side with Lin Wei.
