Undercover Ninja: Secret Assassins (1983)

Following the death of the second Tokugawa shogun, it is revealed that he was poisoned by retainers of his son Iemitsu in hopes of gaining him the shogunate despite the stammer and birthmark which undermine his respect. Iemitsu and his brother Tadanaga become bitter rivals for the shogunate, and the land is split into factions, eventually erupting into warfare. Iemitsu's mentor, his fencing instructor Yagyu, is fixated upon securing Iemitsu the shogunate and ends up betraying everyone, even his own family, in pursuit of the goal.

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.

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.
