Young lord investigates the mysterious death that takes place in the underworld.

The famed ninja Yagyu Jubei fights to suppress a coup d’etat plotted against Tokugawa Shogunate.

In the fourth film in this exciting series, and the first since losing his left eye, Yagyu Jubei is charged again with the task of protecting the Yagyu Secret Scrolls. The two scrolls are held in separate locations to assure their safety. Within them there is information other than the techniques of the Yagyu Shin-kage style. They contain a secret that could throw the country into turmoil. Clan founder Yagyu Sekishusai had split the scroll into two parts to prevent its contents from being known to the public. This is Jubei's toughest assignment yet as he puts his life on the line to save the nation!

This time, sword-saint Yagyu Jubei battles the evil corruption in Akizuki Village, with the help of his friend, a samurai named Matashichiro. This spaghetti western style action swordplay film is exciting and dynamic from start to finish! One-eyed master of martial arts, Yagyu Jubei visits Akizuki Village and meets with his former teacher Akizuki Hayato-no-Kami. Jubei is shocked to see Hayato's sickly appearance. An evil gang has plotted to murder Hayato, but a deadly Yagyu blade will unleash a rain of blood and disperse the evil plot! The breathtaking climax in a huge ravine called Okamidani is the ultimiate pay-off. Jubei confronts several hundred riflemen and warriors in a bloody battle to the death.
