Camilla tries to convince Susy to get Tucci out of her head, who has disappeared but has definitely left his mark.

After leaving Tucci's office, Camilla confides to Susy that she suspects Sabrina is friends with Taviani. Having arrived in front of Livietta's school, Susy fears another interrogation by Gaetano and runs away... but she's not the only one doing so.

Camilla reports to Gaetano what she discovered by talking to Tucci's secretary and also explains her theory to him. Later she goes to the dentist's office for a treatment, while Renzo is busy with his personal blackbird hunt.

Gaetano returns to the police station with the children. Meanwhile, Torre has carried out some checks on Tucci's secretary, while he and Berardi go to question the craftsman reported by Camilla. In the meantime, while Livietta is in tears, Renzo arrives with good news.

Roberta, annoyed by Gaetano's behavior, decides to return to her home. Meanwhile, Camilla and Susy ask one of the students to trace the address from which Tucci sent the message, while Gaetano provides instructions on how to tail the secretary.

In Fregene, Berardi and Torre discover that Camilla and her friend Susy are also there, on Tucci's trail. Following Sabrina, they all end up in front of an isolated villa. But as soon as they see it, they understand that this is not Tucci's house.

Susi, convinced that Tucci was gone for good, is surprised to see him reappear at the villa, armed and attempting to escape. He has the upper hand with his gun, but he gets some surprises, too. Finally, the suspects start talking.

Sabrina tells the story of her encounter with Matilde and explains about the diary. Appropriate arrests are carried out. In front of the school, Berardi comes to apologize to Susy, while the principal is waiting to take her out to lunch.

Gaetano asks Camilla how she figured out that Sabrina was Taviani's lover and congratulates her on her skill. As they decide to go to lunch together, a phone call arrives from Roberta, who wants to make peace with Gaetano. Meanwhile, at home, Renzo gets lost in an unusual conversation and prepares a disastrous dinner.

Camilla finds herself dealing with Livietta's preadolescent demands, who has to go to a party and complains about having nothing to wear because she lacks low-waisted pants. Meanwhile, Renzo has a business lunch, hoping that a useful contact for his career might emerge.

A controversy has erupted in front of the school, as principal Mazzeo opposes the distribution of flyers by a former student. However, Susy will manage to make him reconsider his decisions. Meanwhile, the new physical education teacher arrives and introduces himself to his colleagues.

In the La Luna Nuova restaurant, dialogues about work, friendships and the past intertwine, until a phone call announces the discovery of a dead woman, breaking the normalcy and creating tension.

While Renzo celebrates a special occasion, at the police station investigators search for leads on the murder of a young woman found in a dump. Among abandoned cars and small clues, new details emerge, while at home Camilla tries to bring serenity back into the lives of the people she cares about.

Renzo, left without work, goes through a moment of deep frustration and is hurt when he discovers that Camilla tried to help him by turning to Gaetano. Between jealousy, pride and hurtful words, a domestic argument breaks out between the two that ends with Renzo's decision to go sleep on the studio couch.

Gaetano and Camilla discuss their relationship difficulties, including jealousy and advice on how to communicate better. The conversation intertwines with investigative work when Camilla asks for more information regarding the recent murder.
