	As described in a film magazine, the Russo-Japanese War of 1904-1905 threatens the peace of Japan, so Yuki Onda (Aoki) is directed home from her American school by her father (Seki). With her sails a party of American diplomatic friends that includes Pierre Le Beau (Wheatcroft), to whom Yuki has pledged her love. Her father's faith in her inherited honor obliges her to marry Prince Hagane (Carewe), and in the opportunity to be of service to her country comes an opposing loyalty to him and love for Le Beau. Le Beau is an attache of the embassy of Australia in Japan, and he is made an unwilling instrument in an attempt to secure valuable information from her. Yuki, believing that she has failed in her trust, takes her own life, leaving a sorrowing Prince and the penitent and loving Le Beau.
