Onna de aru koto (1958)

Married for a decade, a couple have no child. He is a lawyer, however, and as a result of one of his cases has the daughter of an imprisoned man living with them. The girl, who is understated, has a boyfriend, but otherwise only ventures out to meet her jailed father. The family is visited by the daughter of a friend from Osaka who has made the journey without informing her parents. That her personality is the opposite of the girl who lives in the house is obvious. At the same time, the wife runs into her own ex and the husband faints at work due to exhaustion. The live-in girl tends to the husband in a way that leaves the latter's wife concerned.
