Note that "Boxer's Adventure" is an alternate title for this movie. It is the title that is on the Ocean Shores VHS box. Dr. Craig Reid's book "The Ultimate Guide to Martial Arts Movies of the 1970s" also lists a movie titled "Boxer's Adventure". The movie reviewed by Dr. Reid has no alternate titles and stars Mang Fei and Blacky Ko.
This movie opens to soldiers fighting in a war. Barry Chan goes from war hero to street performer with some children. There are problems with the tax collector. Barry leaves and for some reason Nancy Yen follows him and they fight. He exchanges a few blows then runs off with the kids. A street vendor (Sit Hon) who challenged the tax collectors discusses the situation with an elder. Then he finds people murdered. Cut back to Suen Lam the tax collector and now Nancy Yen challenges his authority. Then she finds her parents murdered. Her uncle is Sit Hon and they talk. Then they are attacked by a gang. One admits being the murderer. Nancy submits her grievance to Barry's former general. The official is about to confess the whole story but he is silenced by a dart. One of the best bad guys ever, Pai Ying, steps on stage as the top bad guy in this story too.
The picture is full screen and good quality but VHS cropped sides. There are high production values, a coherent story line, great stunt men, and actors who can also fight. About the last thirty minutes of the movie is non-stop action. I recommend this movie for all fans of the genre and rate it above average.
