Tenchu aka. Hitokiri- directed by Hideo Gosha - starring Shintaro Katsu and Tetsuya NAkadei belongs (together with Goyokin, HAra Kiri & Rebellion) to the best chambara movies existing.
Its the story about Shintaro Katsu (who plays Okada Izo) working for Nakadei, who wants to become the daymio. Okada, being the "cleaner" for Nakadei is being treated like a dog - and after quite a while he realises - what he realy is to Nakadei.
But there is so much more in this movie - every fan of japanese cinema should have seen it !!!!!!!
(Tenchu means Heavens Punishment)
