The disappearance of her old friend, Lila Cerrullo, causes 60-year-old author Elena Greco to reflect on the early days of their friendship in 1950s Naples, when Elena and Lila are two very different girls at the top of their class. When the girls discover the lair of Don Achille, a criminal figure who controls the neighborhood, they decide to confront him.

As fourth grade draws to an end, Elena and Lila fight with their families for the chance to continue their education. Later, a trip out of town becomes a day Elena will never forget, and a death changes things in the neighborhood forever.

After Nino's unexpected appearance at her book presentation in Milan, Elena realizes her childhood crush never really abandoned her, and doubts begin to form about her fiance Pietro. Later, a scathing review leaves Elena questioning herself as a writer.

A nervous Elena introduces Pietro to her family, and, though he instantly charms his future in-laws, Immacolata rejects their plans for a civil wedding ceremony. Months later, Lila falls ill due to the deplorable conditions at the Soccavo factory and makes Elena promise to take care of her son Gennaro if anything happens to her.
