While the original from 1964 starred the great old-time actor Konoe Jushiro, this version is perfectly cast with his son Matsukata Hiroki in the lead as Wadakuro, one of four ronin hired to fight against the Shogunate's plot to abolish the Gamo Clan, who are struggling to reinstate their young heir Tanemaru as their Lord. Facing the threat of the Koga Ninja, Wadakuro shows his own cruelty while on a personal vendetta.
