Lojacono and Aragona go to Ramaglia's house to talk to his wife and daughter. After some questioning, the daughter Rosa remembers someone that might turn out to be important. Later on at headquarters, Aragona has a hard time using appropriate nomenclature for Blacks and people of color as they discuss the case.

Lojacono and Di Nardo go to talk to Doctor Martone in Forensics. Di Nardo appears to know quite a bit about weapons. Back at headquarters, Romano and Aragona report to the Chief about what they found out from the prison director.

Romano goes home expecting to see Giorgia, but she's not there. Di Nardo has her parents to deal with, but also gets an interesting text while sitting in front of the TV. The next morning, Ramaglia's daughter is trying to identify the person who had argued with her father before his death.

Lojacono and Aragona are able to find Bukhar and question him. Ottavia goes home with some fried rice balls, thinking they will be appreciated, but her husband criticizes her.

Lojacono meets his friend Paolo for dinner and they talk about the case in which Lojacono had been falsely accused. The next day, Bukhar is questioned at headquarters.

The team hears about a new homicide that likely is connected to the first one, so they have to go back to square one, more or less. The forensics expert wonders why Di Nardo doesn't answer her text messages.

The team goes to search Capuano's home and then they go to the club to get more information about him. That leads them to a boxing club.

Romano and Aragona go to talk to Castrovetere, who is in prison, to find out what he might have had to do with the murders. Pisaniello is on the huge escalator down to the metropolitana when he sees people running. He rushes to find out what's going on.

Ottavia is having a hard time with her complicated family situation. Lojacono and D.A. Piras go to see the Filangeri sisters to show them the photo of Capuano.

Lojacono and DA Piras once again go to see the Filangeri sisters who say they had never met Cosimo Capuano. The sisters and some friends have plans to play the game of Burraco, a card game. Later, Ottavia does a bit of research about Capuano and the team connects some dots. Lojacono goes to the Alba Rossa Yacht Club to do some checking up.

Some members of the team go back to the prison to have another chat with Castrotevere, who gives them some very important information. And then they go back to the Filangieri house, where the old ladies are still playing cards.

The agents arrive at the Filangieri house with a warrant and Lojacono asks Clelia some questions about the girl in the photo. Clelia decides to send her friends home, canceling the Burraco game.

As far as Clelia is concerned, she has told the police everything about how the murder took place. The DA and Lojacono still have grave doubts.

Lojacono and the DA go back to the nightclub to see the homeless guy. He knows what kind of car he saw the night of the murder.

Pisanelli goes to see a pharmacist friend who gives him a hand in his private investigation. Romano brought home pizza, but once again, Giorgia arrives late. At police headquarters, the team is celebrating having solved the case.
