Carlina returns to Milan from the United States and reunites with an old friend with whom she will begin a romantic relationship.

Paola and Andrea find out they both loved (and lost) the same man. They get over their mutual distrust and their friendship gradually develops to the point that they feel they should marry one another, but without giving up their personal freedom and sexual predilections. Theirs is a true love match: a marriage based on friendship and mutual respect, where sex does not come into the equation. The question is, will they stay together, or will society and its mores intervene?

A man and a woman, each them alone after an abortive love affair, and trying to re-establish a sort of equilibrium in their emotional life.
