During the
Heiji Rebellion, samurai Endō Morito is assigned to escort
lady-in-waiting Kesa away from the palace after she had volunteered to disguise herself as the
daimyō’s sister, giving the daimyō’s father and real sister time to escape unseen. Kesa is knocked unconscious when the rebels attack their caravan, and Morito takes her to his brother’s home. When Morito’s brother arrives, he reveals that he too is part of the rebellion and suggests Morito join him. Morito refuses to betray the daimyō, Lord
Kiyomori. Once he and Kesa are safe, Morito proves his loyalty to Kiyomori by personally riding to him to deliver news about the insurrection, including his brother's disloyalty. After the coup has failed, Morito encounters Kesa again. Infatuated with her, he asks Lord Kiyomori, who is granting one wish to each of the loyal warriors who helped put down the rebellion, to grant him Kesa’s hand in marriage. He is informed that Kesa is already married to Wataru, a samurai of the Imperial Guard, but Morito demands that his wish be granted. Kesa is concerned by Morito's determination, but Wataru promises to protect her. After hearing Kesa perform
koto music, Lord Kiyomori begins to sympathize with Morito. He decides to give Morito a chance to compete for Kesa’s hand. Morito enters a horse race in which Wataru is competing, and outrides him. However, after the race is over, he nearly attacks Wataru at a “Forget the Race” dinner, visibly disturbing everyone around him. Morito goes to speak to Kesa. At Kesa's request, her handmaid Tone tells Morito that Kesa has gone to visit her aunt. Morito goes to the aunt's home and discovers the lie. He forces the aunt to write a note to Kesa claiming she is ill and needs Kesa to come and see her. Kesa is terrified to find Morito waiting for her. When Morito threatens to kill Wataru and Kesa and her aunt if he cannot have his way, Kesa tells him she will fulfill his heart’s desires. She agrees to a plan for Morito to kill Wataru and claim her once she is widowed. Kesa returns home and behaves generously to Tone and lovingly to Wataru. After everyone has gone to bed, Morito sneaks into the bedroom and kills the figure beneath the blankets with his sword. He is horrified to discover that he has killed Kesa. Realizing that Kesa has sacrificed herself rather than subject herself or anyone else to his insanity, Morito fruitlessly begs Wataru to kill him in penance. As Wataru mourns his dead wife, Morito kneels in the courtyard, cuts off his samurai topknot and vows to live thereafter as a monk. ==Cast==
