This film is the memoirs of Takasugi Shinsaku about the life of his great teacher Yoshida Shoin. Yoshida Shōin (吉田 松陰, 1830-1859) was one of the most distinguished intellectuals in the closing days of the Tokugawa shogunate. He devoted to developing many Ishin Shishi who made an outstanding contribution to the Meiji Restoration. At least two of his students, Takasugi Shinsaku and Itō Hirobumi later became famous, and virtually all of the survivors of the Sonjuku group became officers in the Meiji Restoration. Takasugi led rifle companies against the shogun’s army when it failed to conquer Chōshū in 1864, rapidly leading to the fall of the Tokugawa Shogunate. Ito Hirobumi became Japan’s first prime minister. His admirer, Maebara Issei, was later killed rebelling against the Meiji regime. He is now enshrined in Setagayaku-（世田谷区）Tokyo, Japan.
