Francesca is a 17 yrs old girl who, one morning, wakes up after dreaming of making love with a family friend, Enrico, an architect 20 years older than her. After getting up, instead of going to school, she goes to see him, clearly showing him her feelings. After spending the rest of the morning with some friends, she decides to go to see Enrico in Marino, a small town in the hills around Rome, where Enrico is working on the restoration of an old villa.
Francesca, a seventeen-year-old Roman, is finally sure she has found love. Almost sure. She spends the day observing other lovers' behaviors and considering whether she is ready to jump. Her age notwithstanding, this movie is more about coming of age than about improper or illegal romantic relationships. If Catherine Spaak, beautiful and innocent, acts with brio, the quality of the supporting cast makes the movie.
