Plot

While in Florence on business, Roman landscape architect Giulio Marengo meets an alluring college student, Francesca, and spends the night with her. She is the foster daughter of an agriculturist named Bartolo who has looked after her since the death of her mother, Flora. Later, a friend of Giulio's sees Francesca in a restaurant and implies that she might be Giulio's daughter. It is a possibility since Giulio had been going out with Flora the year before Francesca was born. Shocked by the idea, Giulio tries to cool his relationship with Francesca. Meanwhile, he is distracted by the revelation that his unmarried daughter Alexandra, who is about the same age as Francesca, is pregnant.
