Before World War II, three disciples, Taikan, Choei, and Giryu, were taught by karate master Eiken Shibara in a remote mountain dojo. When the Japanese military police attempt to seize the training hall, the three disciples resist and soundly defeat them, though Choei receives a crippling injury.
Afterwards, on his deathbed, their master bids his pupils to focus their skills inward and decide who is worthy of being his successor and inheriting his black belt. Taikan and Giryu, as the only two viable candidates, follow different paths on their journey to discovering the meaning behind their master's last words.
