Following on from the events of Lone Wolf and Cub: Sword of Vengeance comes Kenji Misumi’s sequel Lonewolf and Cub: Baby Cart at the River Styx. This time we find disgraced former executioner Ittō Ogami (once again played by Tomisaburo Wakayama) now living the life of a farmer (and occasional assassin) with his three-year-old son Daigoro (played once more by Akihiro Tomikawa).
Ogami’s activities are being watched by the Shadow Yagyū, a Kurokawa spy clan of shinobi-class ninjas. They report on his activities to Sayaka Yagyu (Kayo Matsuo), head of the Akari Yagyū clan of female assassins. Soon female assassins are on his trail and Lonewolf and Cub must survive whilst at the same time bonding stronger.
