Ebihara is a budding novelist entangled in a complicated web of relationships with three women from three different generations: Kazue, a coquettish teenage war orphan who tries to offer herself for money but is instead taken in by Ebihara, Koyabu, a middle-aged woman who has spent much of her life as the kept woman of a wealthy man, and Teruko, the modest daughter of Ebihara's former teacher who comes to rely on him after the death of her father.
Unfortunately the movie The Rainbow-Colored Flower is not yet available on HBO Max.
