When the blind swordsman Zatoichi (Shintaro Katsu) is thrown into jail in a gambling raid, he encounters a man who has been sentenced to death for a crime of which he isnt guilty. The blind warrior tries to help him upon his release. Following the trail to the guilty party, he crosses paths with the son of the man he is assisting, who is impersonating Zatoichi. The search for the truth eventually leads the blind swordsman to an encounter with a gun-wielding assassin. ~ Bruce Eder, All Movie Guide
