Qi Heng, the vice president of the Qizhou Intermediate People's Court, took over the complicated "Fishing Boat Murder Case" as soon as he took office. He unraveled the loopholes in the survivors' testimonies and successfully found out the facts of Zheng Duo's murder. Qi Heng's son Qi Lun saw Zheng Duo on TV and recognized him as the murderer who kidnapped his mother Guo Nian, which led to the discovery of Luo Huaigong, the mastermind behind the scenes. At the same time, Jiangyun Chemical Group, owned by Luo Huaigong, had been discharging pollutants for a long time, causing villagers to suffer from terminal illnesses. The people were angry and sued in court. In order to maintain GDP growth, the city-level leaders asked for mercy. Qi Heng resolutely eliminated interference, enforced the law impartially, and made fair judgments. He was retaliated by Luo Huaigong and almost died. Guo Nian's body was found, and Zheng Duo, who had refused to plead guilty, was killed by Luo Huaigong. With the strong assistance of Qi Heng and others, the public security organs destroyed Luo Huaigong's criminal gang, and the lawbreakers were sentenced fairly by the court. As the last line of defense for maintaining fairness and justice in the world, Qi Heng and his colleagues in the court, under the guidance of the spirit of judicial system reform, use all their energy to maintain social fairness and justice, and to effectively implement the system of rule of law in China.
