Francesco is at dinner at the home of Giorgia's parents. He's scontroso (surly) and seems to have a huge chip on his shoulder. Alex Di Nardo has spent the night with someone and needs to get back to Naples in time to start work.

Imma discusses the dynamics of the case with the coroner. She also talks to the man who discovered the body. The subject comes up at dinner with her in-laws, and the TV is on so she watches the news broadcast about the case, too. Valentina has a new friend named Penelope.

Francesco Romano is not happy to have reports to take care of and he takes it out on a colleague. Palma has to step in. De Nardo is going to meet up with someone at a hotel. Lojacono goes to his usual restaurant, where he shares his worries with Letizia.

As we begin a new episode, Valentina is in Latin class. Her mother, Deputy Prosecutor Imma Tataranni, has arrived at a new crime scene, and is exhibiting her usual, unique, and somewhat bizarre personality traits.

At police headquarters, Ottavia discovers some surprising information about Ramaglia, the driver, so Lojacono and Aragona go back to see the Filangeri sisters, who seem as confused as ever. Palma reports to his boss, who is familiar with the Filangeri family.

The two women tell conflicting stories about the murder and it is frustrating for the officers. De Nardo has some uncomfortable conversations at home with her parents.

The team at Pizzofalone are back in full force. And there is a crime to investigate in the middle of the night.

The pizza party ends up just being Palma and Ottavia who make the best of it. Palma would like them to be on a first-name basis, but he is Ottavia's boss and she has trouble with that. He talks about dare del tu, which means addressing someone informally instead of dare del Lei, which implies addressing someone formally. It can still mean using someone's first name, but the pronouns (and conjugations) change.

After working on the case together, the members of the team go home to deal with their personal lives. Not everyone is enthusiastic about going out for pizza with the chief.

After being left by the taxi driver, Giuseppe goes in search of the Esposito home. The taxi driver was right about the danger. Meanwhile, Giorgio shows up at the dinner and greets Elena and her father.

There's a press conference announcing the success of the investigation. Rather than singling out Lojacono and Aragona, Palma gives credit to his entire team, as well as to Dr. Piras.

Lojacono and Aragona, with De Lucia's recounting, are able to reconstruct the murder. We then learn what was written in the letter the notary's wife sent to him.

Sister Helga and Moscati give the patient a bath and talk about how medicine is nothing without love. Moscati has some unorthodox teaching methods, as well as some novel "therapy" for his patients.

Having discovered who bought the glass globe, Lojacono and Aragona could easily figure out who had killed the notary's wife. They go to see the suspect.

Lojacono and Aragona scour the city to find a glass globe like the one that killed the notary's wife.
