Undercover agent Li Heng of Operation Deer Hunt was forced to disappear into the crowds and continue his investigation in secret after accidentally killing someone.
Gu Feng, editor-in-chief of a magazine, came to Harbor City to find his younger sister, Gu Ziqiu, who had been abducted by a one-eyed man. But after a bizarre and inexplicable corpse-dumping case, the police took him in for questioning.
Three days later, Li Heng was shocked to discover that Gu Feng, the man who had shared a bed with his wife, Lin Qi, had gone to the Nightshade Bar to continue his own undercover mission.
