During feudal unrest in the 12th century, samurai warrior Morit (Kazuo Hasegawa) manages to thwart a palace rebellion and save the life of the empress, using loyal subject Lady Kesa (Machiko Kyo) as a decoy. When Morit is offered anything he should desire as reward, he requests Kesa's hand in marriage. Informed that she is already married to a fellow samurai (Isao Yamagata), he refuses to withdraw his request, setting in motion a tragic chain of events.
