Late one night, a loud explosion was heard at Yangpu Port in Dongjiang City. Yu Zhongjun, secretary of the municipal party committee, rushed to the explosion site overnight, and Zhao Dasheng, secretary of the discipline inspection committee, led a joint investigation team to investigate the explosion of hazardous chemicals at Yangpu Port. Represented by Zhao Dasheng, Zhou Qiang, Song Tianyi and other discipline inspection cadres have successively investigated and dealt with major cases such as the barley chemical pollution case, the Jinghu complex bidding collusion case, and the city leaders colluding with interest groups to monopolize major projects. In the process of investigating and handling various corruption cases, they also encountered various choices and tests. Zhao Dasheng experienced life setbacks such as husband and wife turning against each other, father and son becoming enemies, comrades breaking off friendship, and job adjustments. He overcame many difficulties such as collusion between officials and businessmen, pressure from superiors, and frame-ups and murders by lawbreakers. With the perseverance of party spirit and the will to eliminate evil and punish traitors, he finally brought Mai Siyuan, Yu Zhongjun, Lin Miaoxue and other lawbreakers to justice. Disciplinary inspection cadres represented by Zhao Dasheng would rather lose their jobs than let down the people. They are loyal to their duties and strictly abide by discipline. They safeguard the fundamental interests of the country and the people with practical actions, compete with corrupt elements with great wisdom and courage, and fight selflessly on the front line of the anti-corruption struggle. In the competition with corrupt elements, they constantly undergo the choices and tests of the country and the family, the law and emotion, the soul and desire. Year after year, the wind and rain send spring away. Under the wind and rain of the anti-corruption storm, the vibrant spring that people expect will surely come.
