While attending college in Washington, D.C., Yuki Onda, the daughter of a Japanese samurai, meets and falls in love with Pierre Le Beau, a diplomatic attaché. At the outbreak of the Russo-Japanese War, Pierre is sent to Japan as attaché to the Australian ambassador. When Yuki's father discovers his daughter's romance with a foreigner, he becomes enraged and betroths her to Prince Hagane for political reasons; being an obedient daughter, Yuki agrees to the match. During a political meeting, Yuki's husband commands her to see that nobody enters the house. During her vigil, Pierre arrives, half-crazed with fever and the desire to see his beloved. Out of revenge, he steals an important document from Hagane; believing that his wife has acted in dishonor, Hagane agrees to trade Yuki for the paper. Worn out with grief and struggling against her love for Pierre, Yuki kills herself, and Hagane delivers the body to her true love.—AFI
