This is the sequel to 'Yojimbo'. Toshirô Mifune returns as the wandering ronin Sanjûrô Tsubaki. He encounters nine naive samurai who wants to confront corruption. One of the samurai had confronted his uncle the lord with the accusations. The response was dissatisfying so he tells the superintendent. The superintendent tells the nephew to gather his men. The ronin immediately smells a trap, and the corrupt superintendent launches a raid on the group. Only the ronin's smarts saves the group. Now the uncle and his family are taken prisoner and the ronin endeavors to rescue them with the help of the nine naive samurai. Only the clueless nine are sometimes more problematic with their distrust of the often napping ronin.
This is a funnier movie than Yojimbo. Sanjuro does battle more with his brains than with his sword. The best swords are kept in their sheaths. However there is that great scene of drawing of the swords at the end. The guy imprisoned in the closet has a good funny scene. It's a very good sequel to Yojimbo with a funnier tone.
