During a rebellion in 1159 the samurai Morito desires the lady-in-waiting Kesa but she's already married to Wataru. Morito decides to get rid of his rival. He makes Kesa explain to him how he can kill her husband while he sleeps. Kesa provides very precise instructions, yet when Morito follows through on her plan it is Kesa herself who gets killed. Morito understands that Kesa has sacrificed herself because she was determined to save her Waturu's life and her honour.
