The play is based on real cases. It tells the story of Fang Daqing, deputy director of the Anti-Corruption Bureau of the Second Branch of the People's Procuratorate of Yanzhou City, and Xia Jingru, director of the Public Prosecution Department, who faced complex and difficult cases. They calmly solved the case, unraveled the mystery, and fought wits and courage with criminals. In the process of handling the case, young prosecutors Chen Chen, Yu Yuelong, Zhou Wenwen and others led by Fang and Xia experienced real problems such as love, income, and housing, and endured the hardships of life. In handling Zhou Xiang's murder case, Xia Jingru and Chen Chen found many suspicious points. In the end, the public prosecution released the "murderer" Li Hao, who had served 17 years in prison, and the real murderer Zhou Xiang was sentenced to death in the first instance. In the "Fox Hunt 2014" special operation, Fang, Xia and others set up a special task force. They found that Jin Mingshan, chairman of Yanzhou Group, was suspected of committing crimes with Liu Kaiming, and Jin Mingshan also set obstacles for the task force everywhere. When Xia Jingru learned that her uncle Jin Mingshan, who treated her like a biological daughter, was the leader of the case, she resolutely chose to bring him to justice.
