This movie is a sequel to both God of Gamblers, which included Andy Lau's character, and to All for the Winner, which starred Stephen Chow and Ng Man Tat.
Down on his luck, Chow Sing-Cho (Stephen Chow), seeks out the God of Gamblers, in hopes of becoming his disciple. Unfortunately, the God of Gamblers is unreachable and out of the country, last heard to be in Brazil, and Michael Chan, the Knight of Gamblers (Andy Lau) replaces the God of Gamblers. When a phony attempts to impersonate the Knight of Gamblers in a huge scam, it's up to the real Knight and Saint of Gamblers to team up and defeat their formidable challenger.
