The title refers to a judge who sticks to the letter of the law, won't take bribes, and will order the execution of a prince if he is guilty. He is about to order such an execution but after the opening credits the scene switches and Chan We-Lau is a bumbling judge.
Initially I reviewed this movie in 2015. The first copy I found of this movie was tiresome to watch. There were many missing frames that jerked the action. The subtitles were white on white and sometimes invisible. Years later I came across the "Flash Legs" version. The video is just better enough so as not to be distracting or annoying. You can identify this copy by the "FLK" logo that appears on and off. Check at about the 51 minute mark for one example. The better copy does not make the movie any better.
This is an average movie for the year and genre. Other than Chia Ling's appearance there is nothing special or memorable about it. Only hard core fans of martial arts movies of the golden age from 1967 to 1984 would be interested in this movie today. I am such a fan and for me it was a watch it once, write this review, and never watch it again.
