Jiang Hu tells two stories simultaneously . One story 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). Mr. Hung's wife has just had a child and Lefty feels that Mr. Hung should leave the gang business as he has now become too burdened with family. Mr. Hung is unhappy with Lefty's leadership style. To further complicate matters, it is rumoured that someone is trying to assassinate Mr. Hung. Three underbosses are plotting against Mr. Hung, but the extent of their plotting isn't revealed. The second story is about two teenage low ranking gang members named Yik and Turbo, who are hoping to gain respect and rank in the gangs by performing a hit on a gang leader. The gang leader is not displayed in the movie, and the audience is to expect that Yik and Turbo are planning to murder Mr. Hung. What the audience doesn't know at this stage of the film is that Yik and Turbo are in fact Mr. Hung and Lefty in their youth. This story-line details their journey together up until the assassination, and displays the friendship between the two.
