"Nandu City" is a border city in Southwest China, adjacent to the Golden Triangle region of Southeast Asia. Nandu City is divided between two major drug lord forces: the "Kunsha Group" in North City and the "Xinhehui" in Nancheng.
Lin Xiao, an anti-narcotics policeman from the Criminal Investigation Detachment of Nandu City, codenamed "Lone Wolf". As "Sang Biao", a desperado who just came out of a prison in Southeast Asia is ruthless, perverted, lustful but loyal. Dive deeply into the New Peace Conference.
Sister-in-law Shen Qingman: The 32-year-old widow of Huo Zhenkun, the leader of the New Peace Society, is sexy and beautiful, has a very high IQ, is suspicious and ruthless. Huo Zhenkun was silenced by mysterious forces on the eve of the police closing the net, and Shen Qingman was forced to take over the gang. She suspected that her husband's death was the work of an insider, and was full of temptations for everyone, including Lin Xiao.
Lin Xiao's only upshot was the accidental death of Zhou (codenamed "Father"), the deputy chief of the criminal investigation detachment. Lin Xiao completely lost contact and became a helpless lone army. Before his death, Lao Zhou made an agreement with Lin Xiao that if one day his identity had to be identified through a third party, the secret code would be "three rings of smoke". That is, at the most critical moment, Lin Xiao smoked three cigarettes at the same time. The first one was normal, the second one was lit upside down, and the third one was crushed into pieces and scattered into the air. This code will become the only evidence for the police to identify him.
Lin Xiao started from the lowest peripheral member, fought his way through four levels, and finally met the big boss behind the scenes. However, the identity of the big boss shocked and surprised him.
