It opens to the lumber mill and the Chinese workers are exploited. A fight breaks out and Cliff Lok attempts to stop the fight. He seems to have difficulty pulling his punches though as he kills the foreman. Quite a bit of melodrama follows as he must now run away and leave his ailing mother. He and his cohorts end up in the very same exploited worker situation but now in Thailand.
This movie has all the look and feel of Bruce Lee's "The Big Boss" and that includes the role played by Lee Kwan. The big boss here is the biggest of all – Sek Kin.
There is always the question "What was the best fight sequence ever in the history of martial arts movies?" That can never be answered because simply defining the best is impossible and all is really opinion anyway. I will say this – the final fight in this movie with Cliff Lok against Sek Kin (in my opinion) was the best fight sequence ever as of 1972 when the movie was released. The final fight was brutal and realistic, everything that Bruce Lee attempted in his movies. The moves were genius level choreography and executed with speed, power and focus. There is true mixed martial arts choreography with submission moves, take downs, and ground fighting. Sek Kin even gets Cliff Lok in an arm bar on the ground! That is realism and I loved it.
I've watched over a few thousand martial arts movies and never heard of this one. It is obscure and hard to come by. I know of no legitimate copy ever sold in the USA. This is truly one for the fans and I give it my highest recommendation and rate it above average.
