Ah Xing (Stephen Chow), a bartender who often indulges in the world of comics, admires underworld figures. By chance, he is taken in by gangster boss Wei Jie (Yang Qun) and becomes close friends with his adopted son Ajun (Lin Junxian). The two work together with another subordinate of Wei Jie, Zhu Biao (Sheng Kui'an), and have achieved many extraordinary feats. When Wei Jie plans to find a successor from among his subordinates before retiring, the three of them become the first choice. The three were sent to the Golden Triangle in Thailand to conduct drug transactions, but they didn't want to encounter many twists and turns. After finally completing the mission and returning to Hong Kong, Zhu Biao was killed. Ah Xing was suspected of being the murderer and had to hide. Although Ajun believed that he was innocent, he had no choice. One day, Ah Xing called to meet Ajun, but he didn't want a killer to follow him.
