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.

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.

Between interrogations, conflicting leads and multiplying suspicions, secrets emerge linked to the victim and their private life. Meanwhile Romano faces the weight of his own guilt and the violence he committed but is called back to a sense of responsibility by the group.

Rosaria appears very impressed by Alex's new house and, between one compliment and another, updates her partner on the latest developments in the investigation. Meanwhile Lojacono goes to the restaurant to see Letizia, who welcomes him by offering a rich and inviting selection of typical Neapolitan dishes.

A mysterious phone call casts Lojacono into shadow: a stranger from Agrigento hints at an unpaid mortgage and lets slip a veiled threat.
Meanwhile, Romano focuses all his anguish on little Giorgia. Between fear and hope, the doctors try to reassure him about the child's condition.

While Romano talks with the doctor, he meets Giorgia at the hospital, who is there to assist her hospitalized mother. Meanwhile, at the police station, new clues emerge about a suspect linked to a criminal clan, while Laura and Giuseppe share moments of complicity that lighten the tension of the investigation.

Lojacono pursues and arrests Donato Cuocolo. After attempting to flee and threatening the officers with a brick, he is stopped by Alex Di Nardo. At the police station, the investigators put him under pressure: he risks many years in prison, but he can face a lighter charge if he cooperates.

The police interrogate Cuocolo after the arrest and he tells of having met Lara on the Mergellina waterfront and of having had a casual relationship with her. However, he denies being the father of the child and claims to have an alibi for the night of the murder, suggesting that the culprit could be someone in love with her who was not reciprocated.
