While investigating his friend Chin Ku's (Hwang Jang Lee) death, martial artist Billy Lo (Bruce Lee) is killed. His younger brother, Bobby Lo (Kim Tai Chung), investigates both deaths. His search takes him to Japan, where he befriends Lewis (Roy Horan), master of the Castle Of Death. But when Lewis is brutally murdered, Bobby must investigate the mysterious Fan Yu temple, where he must enter an underground pagoda and face off with the most terrifying of enemies.

Bruce Lee had filmed over 30 minutes of fight scenes for Game of Death (1978) when work was suspended to allow Lee to work on Enter the Dragon (1973). However, Lee died before he could return. Six years later, director Robert Clouse fleshed out a feature around the original footage with a new cast, including two stand-ins for Lee. After the success of Game of Death in Japan, there was high demand for a new Bruce Lee movie there. As a result, much of the movie is filmed in and takes place in Japan.

Tower Of Death guard:
Hey! Who are you?


Bobby Lo:
Me? Jack the Ripper.

Continuity: Many, as Bruce Lee's role in this film was composed entirely of archival footage. Most noticeable is when his character visits the Abbot, who alternates between a man with a grey beard and red costume to a man with a white beard and a yellow costume.
