Imma is taking a vacation day, but is she really capable of that? She goes hiking with Pietro but he slowly realizes she has ulterior motives. By chance, they meet up with Ettore Rossetti, the person who originally found the dead body of Domenico Bruno.

Imma can't help herself and goes to the office. Diana gives her some important information to mull over. The young people are having a little party for Calogiuri who is leaving for his exam in Rome the next day.

Penelope gets some news she shares with Valentina. Imma is upset about Calogiuri's leaving, but throws herself into her work, confronting Bruno's son about his project in Vallone della Femmina.

Imma interviews Giulio Bruno, the son of the murdered architect, Domenico. Giulio seems forthcoming about what happened with his uncle in Argentina.

Lojacono hasn't seen his daughter in a year, and would like to catch up. She has something to tell him, but doesn't say a whole lot more. Meanwhile, another crime has been committed in the city.

Valentina goes to see her grandmother, who may have dementia but can still offer good advice. Imma discovers that her husband plays soccer with the prefect, Moliterni's husband.

There is a new case for the team at Pizzofalcone and Lojacono and Aragona go to the scene of the crime. A young cleaning woman was found dead in the basement of an apartment building.

Diana has some information for Imma, some of it urgent. Imma calls on Calogiuri even though he is about to take his exam.

Lojacono goes to talk with the Scognamiglios, where Teresa had worked as a maid.

Imma and Pietro go to dinner at the prefect's and play with some Latin proverbs. One of these gives Imma an idea about the case.

Lojacono and Aragona talk to different residents of the building where Teresa was killed. Everyone has something to say about her.

Pietro seems to have a great time at the dinner party, while Imma is focused on work and on finding the right moment to talk to her hostess.

Lojacono and Aragona go to see the husband of the ex-door person. He confirms the fight between Giacomo Scognamiglio and Teresa's husband. Back at headquarters, Romano objects to always having to stay there instead of going out as Lojacono and Aragona do.

Imma's excellent memory helps her figure out some details of the murder, as she talks to the brother from Argentina.

Lojacano can't wait to have some time with his daughter, but she has other plans. Pisanelli goes to see his friar friend, Leonardo, at the monastery.
