Enter The Dragon 龍爭虎斗

Enter the Dragon takes Lee to a martial arts competition held on an isolated island ruled by the evil Mr Han. The plot is the most sophisticated of any of Bruce Lee's films. Lee plays a secret agent who has been hired to uncover Han's illegal opium ring. Interlaced with the central storyline, however, is a sub plot that involves Lee avenging his sister who lost her life after being attacked by a gang of Han's henchmen.
