The drama focuses on the growth of young policemen, and describes the daily life, feelings, setbacks and growth experiences of urban young policemen.
Ten years ago, Zhao Pengcheng (Yu Yi) was attacked by a gunman when he was on duty. When he was shooting, he got stuck. At the critical moment, the master Xu Lei stood in front of him and shot and killed the criminal. He was also injured. This is Zhao Pengcheng's heavy psychological pressure at home and at work.
Ten years later, Zhao Pengcheng and Gao Liu Road were attacked by the police while trying the case. When a warning shot was fired at Gao Liu Road, a shell injured passers-by, causing an accidental "fire" and the defendant went to court.
The case caused the police to think about the laws and regulations on the use of guns. Criminal defense lawyers Chi Yu and Zhao Pengcheng are looking for important direct evidence to wash away the crime of Gao Liu Road. Zhao Pengcheng admitted to Gao Liu Road that he reported a "fire accident", but this was misunderstood by everyone.
When dealing with the robbery again, Zhao Pengcheng stopped in front of Gao Liu Road and killed the criminals, letting everyone know the practical significance of his report on the "fire accident".
