The Lonely Swordsman (Part 2) (1957)

A group of travelers is stranded in a small country inn when the river floods during heavy rains. As the bad weather continues, tensions rise amongst the trapped travelers.

Ogami Itto is hired to kill a tattooed female assassin and battles Retsudo, head of the Yagyu clan, and his son Gunbei.

Official Shogunate executioner Ogami Itto has been framed for disloyalty to the Shogunate by the Yagyu clan, against whom he now is waging a one-man war, along with his infant son, Daigoro.

Japan, 1860. The men of the Mito clan, victims of the Ansei purge, anxiously prowl around the Sakurada Gate of Edo Castle with the intention of assassinating Naosuke Ii of Hikone, tairō of the Tokugawa shogunate and responsible for their misfortune.

A sadistic Daimyo (feudal lord) rapes a woman and murders both her and her husband, but even when one of his own vassals commits suicide to bring attention to the crime, the matter is quickly hushed up. Not only will there be no punishment, but because the Daimyo is the Shogun's younger brother, he will soon be appointed to a high political position from which he could wreak even more havoc. Convinced that the fate of the Shogunate hangs in the balance, a plot is hatched to assassinate the Daimyo. The two most brilliant strategic minds of their generation find themselves pitted against each other; one is tasked to defend a man he despises, and has a small army at his disposal. The other is given a suicide mission, and has 12 brave men. They are the 13 Assassins.

With most of his family already dead at Ogami Itto's hands, Retsudo launches one final plot to destroy him, and when that fails, unleashes the fury of every remaining member of the Yagyu clan.

In 1863, when American warships approach Japan, an enigmatic ronin becomes an important figure in a complex game of power between the Shogunate and the empire.

Ogami Itto is challenged by a quintet of warriors, each armed with one fifth of Ogami's assassin fee and one fifth of the information he needs to complete his assignment.

In 1879, Kenshin and his allies face their strongest enemy yet: his former brother-in-law Enishi Yukishiro and his minions, who've vowed their revenge.

In mid-19th century Edo period, a masterless rōnin named Mokunoshin Tsuzuki resides in a peaceful village among those he helps. However, as the prevalent peace and tranquility are sure to be replaced by war and conflict across the land, the swordsman feels restlessness creeping upon him.
