It starts at the martial arts school and Jason Pai Piao spars the blind master. They discuss the coming tournament but the master forbids his students to participate. Cut to a televised match that is such a bad fight I was ready to give up on this movie before ten minutes in. The fights look like the phoniest professional wrestling fights not martial arts. That is my personal worst possible insult. To be fair, the fights other than in the tournament were not bad at all.
The gangster's fighter is "Gorilla" and he fights a student of the blind master to a draw. This gets him killed in a street fight. Jason steps in to fight Gorilla next but the gangsters do everything possible to cheat. Jason will have to fight blind so good thing he has a blind teacher. What a coincidence!
In 1972 Jason Pai Piao starred in some South Korean location movies including "The Crush", "Action Tae Kwan Do", and this movie. This seems to have been an attempt to make him the next big martial arts movie star. That never happened but he did have an enduring career.
South Korean martial arts movies made in the early 1970s were made to a single standard - to look like early 1970s Hong Kong martial arts movies. This movie did that and nothing more.
I am on a mission to watch and review every martial arts movie of the golden age from 1967 to 1984. Sometimes I watch the movie just to write the review and will never watch it again. This is one of those movies. I watched it so you do not have to.
