The squad interrogates Pupi, the murder victim's coworker at the winery. Luca gets to listen in on the interrogation and the ensuing discussions via Toscani's cellphone.

Adriano asks Karen Bates to travel to Italy's southern regions to scout out a location for an Olivetti factory. Mauro, after being passed over for a job, decides to go and work for Dalmasso.

Marta has conversations with both Manara and Raimondi, neither of which is she too happy about. The term innominato or unnamed makes reference to the evil character in Alessandro Manzoni's novel, I Promessi Sposi (The Betrothed).

We learn why Dalmasso asked Mauro to stay on at the Olivetti firm. Adriano pays a visit to Mauro's house to find out if his suspicions are correct.

Manara sneaks up on the winery owner's daughter and the stockroom guy. Toscani and Sardi ask Manara to run an errand, claiming they have 41° C fevers [105.8° F] as a ruse to get him to come over.

After his encounter with Mauro, Adriano faints on the sidewalk. Grazia reads about his fainting in the newspaper and visits Adriano in the hospital.

Luca goes to see Sardi and Toscani. He opens the door and sees a familiar face he hasn't seen in a while. They go out for some seafood together.

Adriano's illness and hospital stay bring about a pivotal moment for relations between Grazia and her father, and not only them.

Marta and Ginevra talk about the toxicological report, but also about personal things. Luca and Lara say goodbye to each other, and Luca connects with Stefani's daughter by chance, giving him another opportunity to participate in the investigation.

Paola makes a quick decision upon meeting Grazia. Karen Bates comes back with some footage for Adriano to look at.

The questioning continues at the station house. Manara's co-workers are keeping him up to date, in person. But they get an unexpected visit.

Adriano's new idea is to open a factory in the south of Italy, a very poor part of Italy. Convincing his board is a huge challenge. He takes Karen and her camera around the southern part of the country to scout for locations.

Luca gathers some more information about the case when he goes to see Laura's mother. Toscani and Marta go to the place where the DVD was thrown away.

Adriano imagines his new factory and describes the layout to Karen. The workers in Dalmasso's factory are not happy about their working conditions and Mauro manages to placate them. Dalmasso notices his skill in dealing with people and has a new idea of a job for him.

Manara may have been suspended, but that's not keeping him from working on the case in his way. Buttafuoco and Barbagallo go to the dump to find the DVD.
