Pretty standard fare as far as 70s martial arts flicks go. However, notable for the role of 'Teacher' played by Hapkido founder Grandmaster Ji Han Jae. Some great fight scenes (watch Grandmaster pulverise his students ;]). Also good to watch Angela Mao and Samo Hung in some decent fight scenes. A very interesting 'must-see' for all Hapkido (and other martial arts) students.
