Guangzhou is in bad shape politically in the 1930s. Gangsterism was rampant and opium was traded openly. The government witnessed the soaring profits from opium trade and as such set up the Anti Smoking Bureau to supress it. However, the bureau was merely a front as it is under the influence of Cheng Long Kwan, the most powerful druglord in Guangzhou. His eldest daughter, Cheng Kau Mui is an unscrupulous person with a very manipulative mind. She soon returned to Guangzhou to manage her father's drug business.
Lau Sing heads the Criminal Investigation Team in the police force. He has led a tough life and worked very hard to provide for his family, especially his bed-ridden sister, Lau Ching. Lau Sing has a hot temper but beneath it lies a man who values friendship and brotherhood. He almost gave his life just to save his timid teammate, Tong Kat.
