The Secret of the Urn

After losing both an eye and an arm to treachery, Samanosuke (Kinnosuke Nakamura aka Kinnosuke Yorozuya) becomes a ronin who calls himself Tange Sazen. When a stolen urn that contains the secret to a treasure worth a million gold coins falls into his one remaining hand, all sorts of villains, including a high-ranking Shogunate minister, plot to relieve him of his burden - and his life. Unfortunately for them, Tange has developed a unique and deadly one-handed fighting style, which means his enemies will have their hands full - at least while they still have their heads!
