Ni Xiangdong (played by Yin Fang) received a message from his friend Cao Xiaojun (played by Bai Yufan).At the request of a young man (played by the actor), he transported a wooden box to an abandoned cabin on a barren mountain, only to accidentally discover that the box contained the body of Cao Xiaojun.Cao Xiaojun’s wife Wu Ximei (Li Gengxi) called the police to find her missing husband, and alluded to everything being related to Ni Xiangdong.As a witness, Wu Ximei's confession was inconsistent, and the couple's child was not Cao Xiaojun's biological child.Under continuous questioning by the police, Wu Ximei was forced to tell the past events of the three people.

The three were once friends. Wu Ximei and Ni Xiangdong were lovers. Ni Xiangdong was unwilling to take responsibility for the child, so Cao Xiaojun stepped forward and took her away to raise the child together.During the investigation, the police further discovered that Wu Ximei's child was not related by blood to Ni Xiangdong. There were two completely different opinions on Ni Xiangdong: people from his hometown said that Ni Xiangdong did all kinds of evil; workers said that he was kind to others and supported an old man named Xu.

Veteran police officer Meng Chao (played by Zhang Zhehua) and newcomer Tong Hao (played by Xu Aojun) went from the northern coast to the dense forests of the south, uncovering the serial killings that Wu Ximei, Cao Xiaojun, and Ni Xiangdong had been entangled for more than ten years, so that the perpetrators could be punished by law.
