As the Shogun lays dying, seventeen Iga clan ninja are sent to infiltrate the impenetrable fortress where his youngest son is preparing to storm Edo Castle and name himself Shogun by force of arms. They are to either steal the documents that will eventually give him lawful claim to rulership, or they are to assassinate him. But even before they reach the castle walls, they find their every move countered by a ruthless ninja hunter in the employ of the would-be usurper (Konoe), who not only knows their every tactic but knows the exact make-up of their team thanks to his own spies within Edo Castle. As the Iga Ninja fall one by one, the mission’s success or complete failure–where failure will result in a bloody war of succession–comes to hinge on a single young and inexperienced ninja (Kotaro).

Kataoka Chiezo stars as Murasaki Zukin, a mysterious hero of the people who helps those in need. Now under the rule of the evil Tanuma, the people look to Murasaki Zukin more than ever, to confront and punish those who bring misfortune upon the commoners. Will he be able to bring peace to the land? One of the greatest actors from Toei Studios, known mainly for his swashbuckling roles as powerful swordsmen such as Ryunosuke in SOULS IN THE MOONLIGHT, he appeared in 325 films both before and after the war, beginning with CHUSHINGURA in 1928, and including KUNISADA CHUJI in 1933, and DOKUGANRYO MASAMUNE. While best known for his swordplay, Chiezo really did not enjoy the action, but was able to use his menacing presence to stare down his adversaries. Although Kataoka Chiezo passed away in 1983 at the age of 79, he still has many fans today. This film shows him at his best.
