Jiang Hu tells two stories simultaneously. The first is about a gang leader, Mr. Hung (played by Andy Lau), and the tensions that arise between him and his old friend and second-in-command, Lefty (played by Jacky Cheung), due to Mr. Hung's wife's recent childbirth. Now that Hung is with a child, Lefty feels that Hung should leave the gang business as he is now burdened with family and that will appear weak in character to their own under-bosses. Lefty also believes that it is his own turn to run the business in his own direction. However, Hung is unhappy with Lefty's leadership style of fear and brutality to keep his underlings in line, and is hesitant to cede power to Lefty. To further complicate matters, news of Hung becoming a father has spread unrest amongst his under-bosses, and there are rumours that someone has placed a hit on Mr. Hung. Suspicion as to who is plotting against Mr. Hung has been placed on three leading underbosses, resulting in Lefty sending loyal henchmen going on a hunt to locate and kill the bosses; one is killed and Mr Hung's henchmen save the other two on Mr Hung's orders. In the end, it is alluded that the guilty party attempts to call off the hit under the guise of checking on his family, however he was unable to follow through with the action after he was assured by Hung's henchman that his family is safe and untouched.
