Mr. Soh, a righteous man with a cold stare and fists of steel, returns to a lawless post-war Japan in 1946. He protects the weak, defends the poor and knocks some good sense into friends and enemies alike. Rapists and gangsters get the worst of it, as Mr. Soh builds up his school on the island of Shikoku.
