Three Hong Kong young martial arts masters - brothers Donnie Yen's Dragon and Nicholas Tse's Tiger plus buddy Black Dragon (Shawn Yue) - put aside their differences while learning skills at the Dragon Tiger Gate and face up against a Japanese secret society headed by the villainous Shibumi. Trivia: a 400 pound punch bag measuring eight feet high was specially constructed for the film...and certified the world's largest by Guinness World Records.
