Tatsuya Nakadai and Toshiro Mifune star in the story of a wandering samurai who exists in a maelstrom of violence. A gifted swordsman—plying his trade during the turbulent final days of Shogunate rule—Ryunosuke (Nakadai) kills without remorse, without mercy. It is a way of life that ultimately leads to madness.

Richard Chamberlain stars as Australian lawyer David Burton, who takes on the defense of a group of aborigines accused of killing one of their own. He suspects the victim has been killed for violating a tribal taboo, but the defendants deny any tribal association. Burton, plagued by apocalyptic visions of water, slowly realizes his own involvement with the aborigines…and their prophecies.
