Ten years into a marriage, the wife is disappointed by the husband's lack of financial success, meaning she has to work and can't treat herself and the husband finds the wife slovenly and mean-spirited: she neither cooks not cleans particularly well and is generally disagreeable. In turn, he alternately ignores her and treats her as a servant. Neither is particularly happy, not helped by their unsatisfactory lodgers. The husband is easily seduced by an ex-colleague, a widow with a small child who needs some security, and considers leaving his wife.

A married Japanese forester during WWII is sent to Indochina to manage forests. He meets a young Japanese typist and promises to leave his wife. He doesn't and after the war, she turns up and the affair resumes.
