Twenty years after he was fired from his job as a spy for a failing a secret mission, Mr. Chan (Dayo Wong), a secret agent, has a new mission thanks to Heung (Charmaine Sheh See-man), the Secretary of Security, whom he had offended during the last major mission. He must use his skills as a secret agent to investigate why many people, including public figures, are behaving bizarrely. His investigation leads him to teen pop stars, Yuki (Larine Tang Yue-ping) and Angela (Cecilia So Lai-han).

      Agent Mr. Chan blends elements of spoof, satire, mystery and action with underwhelming results. If you're familiar with Bond films, you'll be able to count all of the Bond references which already pretty tiresome around the hour mark. The comedic attempts fall flat more often than not and the ones that don't are more amusing than laugh-out-loud funny or witty. For instance, one character says his name is Roger and that women say "more!" whenever they're around him---an obvious joke about the name Roger Moore. The plot becomes increasingly silly as it progresses with very little wit, and the jokes also get repeated. Also, there are some corny and clunky scenes toward the end that try to tug at your heartstrings. The actors seem to be having fun, but if only the same could be said about the audience. Even at a running time of 1 hour and 41 minutes, the film overstays its welcome and makes the superior Austin Powers look like a masterpiece. It's just as dull as the French spoof of James Bond, Le Magnifique and Casino Royale from 1967.
