A train journeying through America, transporting the newly named Japanese Imperial Ambassador, becomes the target of a robbery orchestrated by “Gauche” (Alain Delon) and his crew. Their prize: a samurai sword intended as a present from the Meiji Emperor to President Grant. The task of recovering the stolen item now rests with "Jubei" (Toshirô Mifune), who finds an unexpected ally in one member of the gang, “Link” (Charles Bronson), inadvertently left behind. As they work together, a connection develops between these men and their respective backgrounds, revealing a shared animosity toward “Gauche.” This conflict leads them to the establishment run by his lover "Cristina" (Ursula Andress) and into several action sequences where Mifune showcases his refined—though occasionally inappropriate—swordplay. The interaction between the two main characters is genuinely enjoyable, but the movie itself feels stretched out and moves at a leisurely pace, possessing elements reminiscent of a somber spaghetti western soundtracked by Maurice Jarre rather than Ennio Morricone. It’s easy enough to watch, and Bronson seems to be having a good time, but ultimately it's unremarkable entertainment with dialogue that appears lifted from a basic screenplay guide for young children.
