Cabbie-turned-chauffeur Jimmy Tong (JACKIE CHAN) learns there is really only one rule when you work for playboy millionaire Clark Devlin (JASON ISAACS): never touch Devlin's prized tuxedo. But when Devlin is temporarily put out of commission in an explosive "accident", Jimmy puts on the tux and soon discovers that this extraordinary suit may be more black belt than black tie. Suddenly thrust into a dangerous world of espionage, paired with a rookie partner (JENNIFER LOVE HEWITT) as inexperienced as he is, Jimmy becomes an unwitting-if impeccably dressed-secret agent.
