It starts with a Jason Pai Piao picture album over the opening credits. The students of all ages are practicing Tai Kwan Do. Cut to a Japanese gang tramples a Korean guy then bothers a woman. They scratch a mark on her door. Jason arrives and talks to a woman about the mark.
The Japanese arrive at the martial arts school and insult them. A man resists and loses an arm. Another man challenges a Japanese to hand to hand. Soon they all fight. Jason arrives and start beating the Japanese. They stop fighting and talk to him.
Cut to an old Korean guy talks to the group. Cut again to two children argue and Jason consoles the little girl. He next fights the Japanese heavy played by Steve Chan Ho and humiliates him in defeat.
This movie is listed as a Hong Kong production but was obviously filmed in South Korea. It was also released in Germany, UK, and Italy. My copy is a computer file that plays as wide screen on a HDTV. There are no subtitles and the dialog is Chinese which I do not speak. I am on a mission to watch every movie made in the golden age of martial arts movies from 1967 to 1984. I have watched many of these movies before and can usually figure out what is going on without the dialog.
This movie was apparently made to feature Jason Pai Piao as the next martial arts movie superstar, maybe as the next Bruce Lee. This was not his break through role. He probably never had a break through role but did have a steady and long lasting movie career. I have read he was a martial artist before acting but cannot confirm this.
Some of the fights in this movie are unique because of the slow motion. I have been watching these movies in chronological order from the 1960s and I believe this is the first time I have seen slow motion used in fight sequences. Otherwise the fights are typical of 1970s fight choreography. There are a lot of fights and a good and long final fight also. Despite a tedious story line, the quantity of fights raises this movie to average for the year and genre.
