Figlia unica.

It's the height of summer in Terracina and Lavinia is at home with her little brother Elia when Giulio, her summer crush, arrives wanting to spend the day with her. Once inside, he distracts the child with a treasure hunt so he can spend some time alone with his sister. Finally alone, Giulio and Lavinia move to her bedroom. Giulio has a new tattoo and Lavinia is so attracted to it that she wants to touch it. It intrigues and frightens her at the same time, almost as much as the idea of changing in front of Giulio to go to the beach, leaving Elia alone at home.
