February 17 to March 3, 1860, inside Edo castle. A group of assassins wait by Sakurada Gate to kill the lord of the House of Ii, a powerful man in the Tokugawa government, which has ruled Japan for 300 years. They suspect a traitor in their midst, and their suspicions fall on Niiro, an impoverished ronin who dreams of samurai status, and Kurihara, an aristocratic samurai who befriends Niiro. [source: IMDB]
