Plot
A katana, one of a pair known as "The Equals", was an heirloom of the Yoshida family, passed down through the generations before being lost during World War II. It was finally tracked down and recovered in California by siblings Toshio and Akiko. Hoping to return the katana to its rightful owner, their father Toru, Toshio hires down-on-his luck prize fighter Rick Murphy to smuggle the sword back to Japan.
Upon their arrival, Murphy and Toshio are captured by thugs working for Turo's estranged brother Hideo, a well-connected kuromaku (or "black curtain" in English, a fixer who works behind the scenes for Yakuza). Toshio is murdered and Murphy is faced with the prospect of being killed by Hideo. Murphy learns that the sword is a fake and himself a decoy, intended to ward off potential thieves. Murphy escapes Hideo's thugs and awakens in Akiko's family home and after a brief stay departs with his money. Hideo's thugs find Murphy and give him two choices: infiltrate Yoshida's martial arts school and obtain the sword, or be beheaded. He takes the infiltration option, yet finds himself being drawn into the ways of Japanese etiquette and tradition to the point where he returns the sword to Toru after having the perfect opportunity to escape with it. Murphy then humbly asks Toru if he can be forgiven and taken back in because he wants to learn the ways of Bushido. Toru agrees, but only if Murphy follows Toru's conditions.
Murphy continues to bumble his way through life at Toru's school until, after a treacherous and almost fatal attempt by one of the higher members of the school to steal the sword, he leaves and is found in a hotel in Kyoto by Toru's surviving child, his daughter Akiko. Finding romance, they go out to see the sights and sounds of the city, including watching a Shinto ceremony. During the hub-bub of the crowded parade, Murphy and Akiko get separated and Hideo's henchmen kidnap her and deliver her to her uncle. Toru, laden with ancient weaponry, ventures out to Hideo's industrial complex where he is shot and wounded by Hideo's bodyguard Ando.
