Two brothers, one deaf and one mute, seek revenge on seven Kung Fu Masters after their father is brutally murdered.

Nam Pae-chun comes to China from Koryo. By chance, he rescues a man named Gu Gu-hwa who came across and stole the Suri sword belonging to Ma Cheon-san. On the run from Chun-san, Gu-hwa becomes Pae-chun's underling. When Pae-chun sees the sword, he realizes that Cheon-san killed his wife. When Pae-chun collapses after getting hit by Gok-gan's poison sphere, Ok-mae helps him. Paechun and Cheon-san pass the five barriers and begin to fight. Pae-chun wins the fight and returns home with Ok-mae. - KMDB
