Defeated samurai Hikosaburo and Manzo are exiled from Japan during the Boshin War in 1868 as the new Meiji government took hold of power in the country. They travel to North America and settle in the mountains of Crow territory. One day Hikosaburo encounters a young native woman who has just given birth hidden in the scrub. Called Running Deer, she tells of how she escaped from two white traders who had "bought" her, and they soon come looking for their possession! Taniguchi's well-researched detail and meticulous artwork reveal an accurate portrayal of the "Indian Wars" of the period, including the infamous Little Big Horn encounter, and present a fascinating view of the daily lives and relationships of the Oglalas, and how the code of honor compares to that of the Samurai.
