It tells the story that prosecutors Feng Sen and Luo gradually became close comrades-in-arms during the investigation of the case. In a series of emergencies, Luo and Feng Sen have a new interpretation of the professionalism of prosecutors and officials in the new era in their daily work.
He Shuguo, the director of the second procuratorial department of the provincial procuratorate, was suddenly attacked by the family members of the local "930 murder case" at the commendation meeting of "Top Ten People under the Rule of Law" in Dongchuan Province. In order to find out the truth, Zhang Youcheng, secretary of the Provincial Political and Legal Committee, appointed prosecutor Feng Sen as the head of the provincial patrol inspection team to investigate the case in depth. After Feng Sen took office, it caused controversy because of his different handling styles.
In the process of restarting the investigation in the "930 case", the fog was gradually uncovered. Feng Sen and Luo, the director of the procuratorial office in prison, faced the truth, did not fear threats, adhered to professional ethics, and made a new legal interpretation of prosecutors' insistence on people's justice in the new era, safeguarding the sanctity and authority of the law.
