Decisive Battle at Kuroda Castle

The film portrays a significant moment in Japanese history, focusing on the aftermath of the massacre of Christians at Shimabara. Followers of Amakusa Shiro unite in a plot against the Tokugawa shogunate, seeking revenge while navigating a succession dispute within the Kuroda clan.
