Three rival martial arts masters each teach traditional Korean, Japanese and Chinese martial arts in a sleepy town small enough for just one gym. The incompetent and ego-driven trio, who also share the same last name, KIM, battle against each other as they try everything possible to lure students and win the heart of the town beauty. But ultimately, they must combine forces and skills to save the town from villainous gangsters.
