The "King of Fists" is Master Chuang, a retired martial artist who now makes a living as an herbalist. The "King of Dollars" is the ruthless Master Chien, a crime boss who rules the local county through bribery and force. Whatever he cannot buy, he relies on hired thugs to enforce his will.

Therefore, there's inevitably going to be a confrontation when Master Chuang aids the local townspeople who beg for someone to stand up to Chien's ruthless refusal to provide medical care to his severely injured mine workers.

Once he fights with Chien's henchmen to secure just compensation, Chuang finds himself unable to escape Chien's wrath. One of Chuang's students gets framed for rape, and sadly, it seems hardly a surprise that those very same townspeople show their ingratitude by hounding Chuang to hand over his disciple with hardly any effort to seek out the facts.

This student is shamed into committing suicide, and other men try to further thin out Chuang's loyal support by ambushing his student "Omelette" (played by veteran Shaw Brothers actor David Chiang) and Chuang's daughter, though the latter two fight off their attackers.

The upshot of this devious plot finds Master Chuang wounded and forced to hide out with his surviving disciples and daughter, and there he tries to refine an "ultimate" fist technique that requires a man and woman to join together in clsoe combat.

There's naturally a big showdown where the villains are ultimately defeated, so in terms of storyline, this movie doesn't significantly stand out among hundreds of other martial arts flicks. None the less, it's got pretty good fight scenes and training sequences. While there are some fast cuts and wirework, they're kept to a minimum and you can see the fight choreography quite clearly.

Moreover, there is a touching dramatic scene where Master Chuang reveals to the girl that he's not her biological father, but he raised her per the will of her mother.

They don't make "old school" martial arts pieces like this anymore, so if you have a few bucks to spare, add this to your kung-fu collection. It's a satisfying, above-average "good triumphs over evil" story.
