Last seen movie: Onibaba (1964)
As a feudal war rages in 14th-century Japan, those left behind are struggling to survive. The wife and the mother of a soldier make their meager living by preying upon hapless samurai who come their way, killing them and selling their armor for food. When a friend of the soldier returns to the women's hut, they learn the fate of their soldier, and are forced to deal with this survivor. Tensions build as the young widow gives in to her loneliness, and the older woman fears abandonment, feels jealousy, and plots revenge.
