The plot is instantly familiar in the great martial arts tradition, being set in a small town which is home to two rival masters, one who practices Taekkyun (Shin Hyun Jun, also in the likes of “Shadowless Sword” and the “Marrying the Mafia” films) and the other Kendo (Choi Sung Kook, also in “Crazy Assassins”), both of who just happen to be called Kim. As well as competing for students, the two are locked in deadly combat for the hand of the local beauty, who seems to be pretty much the only woman in town. Into their conflict comes yet another master Kim, this time a kung fu expert (Kwon Oh Joong, “Damo”) who puts them both to shame with his dizzying skills and suave charm.
