As the team shows up at headquarters for a new day of work, a frantic phone call comes in about a boy found dead. Lojacono and Di Nardo head off to the address provided, to assess the situation.

Lojacono says goodbye to Marinella, who is going back to be with her mother. They make some promises to each other. Pisanelli is watching a building where he suspects something will happen. Aragona is in his hotel room and gets a pleasant surprise.

Mario tells, in detail, what he did. The DA has a few more questions, but then this chapter of the case comes to a close.

The photo of the dead girl reminds Lojacono and Aragona of the statuette they had seen in Marino's shop and Lojacono goes there to have a little chat with the man.

Lojacono and Laura are discussing the case at the crime scene when they discover someone listening to them. This adds a new element to the investigation. As they are leaving the building, they run into the former door person, Rosetta, who is curious about the case. Back at headquarters, Ottavia does some research and Pisanelli's memory is jogged about an old case.

Pietro is asking Ottavia to look at an apartment with him when Ottavia's husband shows up needing a favor. Lojacono has a conversation with Teresa's husband and they clear up some things. Later, Mrs. Vassallo has another meeting with the investigators and the DA.

Fabio Vassallo tells the police he had been involved with Teresa but insists he didn't kill her. Then his wife comes home with the groceries.

The team is putting two and two together regarding the phone records. They discover whose cellphone number had been calling Teresa, repeatedly, before she died. Three detectives go and see someone who had clearly lied to them.

Lojacono and Giacomo have what seems like a fruitful conversation and Lojacono relates what he has learned to the team back at police headquarters. That evening, Di Nardo is stuck at home playing cards with her parents.

Marco has lunch with his father who thinks he needs a better job and wants to help. Lojacono makes a phone call as a result of his talk with Marinella. At police headquarters, the team is talking about asking Giacomo Scognamiglio to come in again.

Lojacono and Marinella have a frank conversation about the past. Palma talks to his superior about the case, to let him know that the Scognamiglio son is a suspect.

Pisanelli meets up with Mr. Musella and goes home with him. They talk about being widowers. Lojacono is waiting for his daughter to come home. Here is where she was.

A woman (from the Veneto region) in the building remembered something she thought might be important. The police questioned Teresa's husband again. Palma asks Ottavia for help finding an apartment.

Lojacono, Palma, and the DA discuss the interview they had had with Giacomo. When they go back to the apartment building where the crime had been committed, they encounter some of the residents whom they now are acquainted with.

Lojacono and Di Nardo go to forensics to find out about evidence on the victim's body and clothing. Palma and Piras question Giacomo Scognamiglio, or at least, they try.
