In 2006, a series of murder cases happened in Baichuan, a small town in Hunan. Leng Xiaobing, a rookie policeman working at the Interpol, initially thought this was a normal investigation, but he didn't expect to meet the murderer face-to-face. However, he could not bring himself to kill the murderer, and this let him go scot-free.
In 2016, Xia Mu just graduated from police academy and reports at the Interpol. However no one noticed that he is the last witness left to the Baichuan murder case.
Leng Xiaobing and Bai Chuan eventually find their investigation leading to the same source - the last victim of the Baichuan murder case. The truth of the incident ten years ago begins to unfold.
