It starts with the loan sharks beating up old Chen. The twist is they take him to work at the timber company to pay the debt. They continue the scam through the town. Our hero, played by Tony Liu Chun-Ku, has been learning martial arts from Jason Pai Piao. He returns to town to find his family destroyed by the gangsters running the timber company.
The title of this movie is actually accurate. It refers to a strong two finger technique that is first demonstrated by the hero poking two holes in a coconut. The movie was filmed in Thailand as obvious by the background architecture.
The movie dragged a bit from too many scenes showing the miserable conditions at the timber company. The total run time was only about 82 minutes so the drag was not extreme. The fights were few but good because of power and focus. The final fight is the best and lasts a satisfying eight minutes.
Overall, for fans of martial arts movies of the golden age from 1967 to 1984 here's another basic, average, typical, run of the mill, ordinary, same old stuff we like to watch once and forget.
