In this sequel to Kurosawa's Yojimbo (1961), the aging, lazy and disloyal samurai Sanjuro happens to witness nine young samurai preparing a revolt against the allegedly corrupt chamberlain of their provincial prince. He makes it clear to the naïve youngsters that they have been mistaken and that their supposed ally, the administrator, wants to capture them, as he has already captured the chamberlain. Sanjuro liberates his wife and daughter and then creeps into the enemy camp to find out the plans of the samurai Hanbei, who is in the service of the steward, and to save the chamberlain himself.
