It begins with Monk Wisdom teaching kung fu to students at Shaolin. The students are not any good and he is criticized for being too hard on them, after all kung fu is really for good health. Problem is, Shaolin is soon to be attacked by political opponents and good fighters will be needed for defense. He goes out in the world to find better students.
The other plot is Sonny, the horse master, learning kung fu from two crippled masters. They got that way from the "horse challenge" at Shaolin.
Sam Chung-Chuen and Thomas Hong Chiu-Ming play the two crippled masters. They originally starred in the 1979 movie "The Crippled Masters." I have tried more than once to watch that movie. The graphic abuse of the two cripples was horrible so I turned it off. In this movie they display their skills without being tormented first.
This movie was made in 1984, the end of an era for these movies. The golden age of martial arts movies was from 1967 to 1984. It ended in a fizzle in 1984 because everything that could be done had been done to death. Yet the genre did not die, instead a new wave began due to the genius of men like Jackie Chan and the Yuen brothers who completely reinvented the genre. This movie is not an example of that but an example of the done to death part.
