The death of the young Ukrainian woman, who had just become a mother, raises many questions: the identity of a rescued child, a possible blood relationship and the evident signs of a murder. Between DNA tests and professional tensions, they attempt to reconstruct the story.

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.

After gathering some confused information from a neighbor about the woman who might have abandoned the newborn, the police decide to enter the apartment. Inside, the body of a woman is found. Procedures are immediately triggered and officer Di Nardo reports the discovery, launching the investigation.

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.

Alex and Giuseppe wander around the neighborhood looking for the girl who might have left the newborn. When they discover her possible residence, they head towards the apartment building and meet what appears to be a neighbor.

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.

Don Salvatore confides to Pisanelli that he received a visit from a young foreign woman and describes some significant details, elements that help the team outline possible scenarios. Meanwhile, the newborn's condition remains critical, with prognosis still guarded.

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.

Romano stays in the hospital to monitor the condition of the newborn found in the dumpster. During the visit, the doctor asks him to choose a name for the little girl. Meanwhile, Pisanelli goes to see Don Salvatore, hoping to get some details about the case from him.

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.

Romano, very worried, accompanies the little girl found abandoned next to the dumpster in the ambulance. Meanwhile, while Lojacono and Alex patrol the neighborhood, at the hospital the doctors immediately get to work to provide first aid to the little one.

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.

Giuseppe announces to his colleagues that he will marry Laura, but he wakes up with a start: it's only a dream. Romano finds a newborn baby near the dumpsters in front of the police station and when the ambulance arrives he asks to be able to go to the hospital with her.

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.

It's almost midnight and everyone goes out on the terrace to toast and be enchanted by the fireworks while Pisanelli remains alone in the house. In front of the television, he makes an incredible discovery that will change everything.
