Weeks after Chan Ho Nam is elected branch leader of Causeway Bay of the "Hung Hing" Society, "Chicken" Chiu, after joining the Taiwanese "San Luen" triad, is reinstated into Hung Hing by Chairman Chiang Tin Sung. At the same time, rival triad "Tung Sing", led by "Camel" Lok begins to make a name for itself, establishing bars and clubs alongside Hung Hing's areas of operations. Things become heated when Tung Sing member "Crow" fuels a deep-seated rivalry between him and Ho Nam, with the threat of open war between the two societies. Meanwhile, Ho Nam's stuttering girlfriend Smartie, who was critically injured in a vehicular accident and slipped into a coma, reawakens but with no prior memories to her meeting with Ho Nam for the first time. Regardless, Ho Nam assures her he and his friends will protect her. To add in a stick of comedy, Father "Lethal Weapon" Lam introduces his daughter Shuk Fan to Chicken, having been good friends and a source of advice for him. During a business trip to Amsterdam with his mistress and Ho Nam, Chairman Chiang is assassinated by thugs. While the rest of Hung Hing believes the hit was orchestrated by Ho Nam, it is the deranged Crow who ordered the chairman's death, using Chiang's mistress to falsify evidence, framing Ho Nam. While Ho Nam goes into hiding back in Hong Kong, Crow is reprimanded by Camel; to add to his insanity, Crow kills his own boss and makes it look like a Hung Hing assassination. Drunk with power, Crow wants nothing more than to destroy Hung Hing and orders his men to search frantically for Ho Nam, who is quick to realize the ambush and escapes with Smartie, until Crow's men manages to separate the two. In their attempt, Smartie is captured but suffers a blow to the head, restoring her memories. Crow tells Ho Nam if he wants his name cleared and his woman back, he must meet him alone. Yet, the crazed Crow does not keep his word and kills Smartie in cold blood in front of Ho Nam. Just as Crow is about to finish him, Chicken bursts in and reaches a stalemate with Crow to ensure Ho Nam's safety. The saddened Ho Nam carries Smartie's body out with him and gives her a proper funeral. Now fueled solely on vengeance, Ho Nam decides to march into Tung Sing territory and kill Crow at Camel's funeral haphazardly. Ho Nam's friends and the rest of Hung Hing manage to capture and threaten Tung Sing member "Tiger", who tells all of Crow's madness in killing both their societies' leaders. Crow is left nowhere to run from his enemies, and in the midst of a Hung Hing/Tung Sing brawl, he is killed in the funeral pyre. With Crow dead, Tung Sing is left in disarray, and Hung Hing re-establishes control in its territories.
