It's 1876, and Captain Nathan Algren (Tom Cruise) is an alcoholic wreck of a man. A veteran of the Civil War as well as General Custer's Indian campaigns, he drifts from one situation to another ostensibly looking for work but really seeking refuge from his inner demons of slaughtering innocent women and children.

Opportunity knocks in the form of an old Army acquaintance Colonel Ben Bagley (Tony Goldwyn), who has accepted work with a Japanese businessman named Omura (Masato Harada). Omura has been charged with recruiting American war vets as military advisors to the new Japanese Army. Emperor Meiji, under advise from Omura and other parties, is interested in modernizing his nation's military with rifles and other armaments.

In order to unify the nation, the powers that be must first take care of civil dissidence within Japan. The samurai, led by charismatic chieftain Katsumoto (Ken Watanabe), are violently opposing the invasion of Western culture into their islands. Bagley foolishly sends his ill-trained soldiers into combat against the samurai, and during the resulting massacre Algren is captured and taken to the samurai's village.

During the course of the winter, Algren slowly gains the trust of his captors and in turn is given free roam over the village. He fights with Uijo (Hiroyuki Sanada), who dislikes the American from the beginning, and is given food and shelter by Taka (Koyuki), the wife of one of samurai he killed during battle.

Katsumoto meanwhile seeks to learn about his enemy, and begins to respect Algren as a fellow warrior. Also interested in the American is Katsumoto's son Nobutada (Shin Koyamada), intrigued by Western culture. Algren finds the first peace he has known in a long time, and begins to adapt to the ways of the samurai. He acts as a surrogate father to Taka's children, learns to sword fight with a kitana blade and begins to respect the culture that he originally sought to destroy.

But during Algren's absence the Japanese Army has had better opportunity to prepare themselves, and time is soon approaching that will determine the fate of the samurai and the future of Japan.
