Diana, after discovering that Giacomo has another wife and two children, Davide and Chicco, abandons him, and leaves for a cruise with her friend Gloria. On the ship he meets Gianluca in the company of Viviana, who is actually staying with him for money. The meeting between Gianluca and Diana is one of those that are not forgotten and, what seemed only physical attraction, turns into true love. Diana is introduced by Gianluca to her daughter and immediately wins her sympathy.
