Movies like Sanjuro

A wandering samurai, Sanjuro, is drawn into local politics. The Superintendent of a clan is plotting to take over the clan by implicating the Chamberlain in corrupt activities (activities the Superintendent is actually responsible for). Part of the plan involves killing off the Chamberlain's staff and, in protecting them, Sanjuro sides with them. The supporters are massively outnumbered so it will require all of Sanjuro's cunning and swordcraft to ensure the Superintendent does not succeed in his evil plan.
