A day in the life of an unfaithful married couple and their steadily deteriorating relationship in Milan.
In a small Italian town, the local youngsters realize that their youth is coming to an end and marriage will soon follow.

A prostitute goes on vacation to a beach resort with her young daughter (who's being schooled by nuns).

But when one of her former clients arrives, her carefree days on the beach are numbered.
