Li Heng, the undercover agent of the Deer Hunting Operation, was found guilty of manslaughter and could only hide in the market and continue the investigation in secret.
Gu Feng, the editor-in-chief of the magazine, came to Haigang City to look for his sister Gu Ziqiu, who was abducted by a one-eyed man. However, he was taken away by the police for investigation due to a bizarre corpse dumping case.
Three days later, Li Heng was shocked to discover that the man named Gu Feng, who slept with his wife Lin Qi, went to the Night Demon Girl Bar to continue his undercover mission.
