In Yunlai City on the border, undercover Lin Kai (played by Huang Xuan) was raided by the anti-narcotics police while doing business with his boss Cheng Yi (played by Wang Yanhui). At a critical moment, Lin Kai rescued the other drug dealer, and was then hijacked all the way to the Golden Triangle, where he came to the lair of the cunning and vicious drug lord Yingying (played by Duan Yihong). Eagle became angry and sent his son and Lin Kai back to Yunlai City to find out who had swallowed his money and goods. After several battles, Lin Kai took the initiative and asked Eagle to hand over the drug management rights in Greater China to him. In fact, this was to get closer to Eagle and catch all these criminals. From the day he walked out of the police academy, he gave his life to the country and the people, so he had to abandon his original identity and walk through this sinful world with the face of a drug dealer.
