Andrew Lau Wai-keung spins this mobland thriller adapted from Niu Lo's cult comic book Cow Man. The film opens with members from the Hung Hing Society whacking another gangster from a rival group who is deep in debt. A comrade with the slain man, sociopathic crime boss Ugly Kwan (Francis Ng Chun-yu) vows revenge and sets his sites on Hung Hing members Chan Ho-nam (Dior Cheng Yee-kin) and Chicken Chiu (Jordan Chan Siu-chan). The two are spirited away to Macau only to be jumped by Kwan's henchmen. Chan's friend is killed while Chan is captured, drugged, and shot on tape having sex with Chicken's girlfriend. Crushed by his friend's perceived betrayal, Chicken leaves for Taiwan while Chan is punished by his gang. Meanwhile, Kwan plots to take over the Hung Hing Society.
