Lojacono immediately goes to Laura's house, where she confides in him that she finally feels ready to take the risk and start a relationship with him, if he wants it too. Although Christmas has already passed, Marinella insists on wanting to put up the tree anyway, but just at that moment Giuseppe receives a phone call.

Everyone is ready to celebrate New Year's when, amid pleasantries and exchanges of good wishes, the police commissioner makes his entrance, surprising everyone with an unexpected announcement.

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.

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.

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.

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.

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.

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.

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.

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.

The investigations are only at the beginning and the autopsy results are not yet available. For now it emerges that there are no signs of struggle and that the girl was caught by surprise. Meanwhile, at home, Giuseppe and Laura rediscover their complicity.

While the little girl hovers between life and death in the hospital, the forensic police and investigators begin to dig into the past of the young woman found dead. A regular residence permit, jobs as a domestic worker in upscale neighborhoods, rent paid in cash and too many unanswered questions.

The circle is tightening and the police are investigating two possible profiles: a lawyer and an engineer. Between jokes and internal dynamics at the police station, two officers are assigned to interrogate engineer Senatore and two others go to Nubila.

Ottavia and Romano speak with Senatore who tells about his ambiguous relationship with Lara, described as an honest, reserved woman full of grace. After rejecting his advances, Lara decides to leave suddenly and when he is told that she was pregnant, the man appears genuinely surprised.

Mrs. Nubila retraces what she knows about Lara, the young woman welcomed with almost filial affection into her family. However, the fragile balance of her life is shattered by her husband's sudden return. Di Nardo and Lojacono reveal to her an aspect of Lara's story that the woman was unaware of.
