Setsuko Hara plays Fumiko, whose unsuccessful marriage has made her become more and more cynical. When her niece, Ayako visits and complains about her own marriage, she is unsurprised. Meanwhile, a new couple, whose marriage is similarly unblissful, moves in next door. The two couples create a very awkward bond that could ruin both marriages, but everyone seems to be aware and nobody cares either...
