Margherita Hack's talents lay not only in her greatness as a scientist, but also in her remarkable ability to communicate with the general public, and especially young people. She rendered complicated information comprehensible and interesting, using clear and simple examples.

Margherita Hack was a scientist and communicator, but she also expressed her opinions about attualità (current events). Part of this segment features a panel discussion she held with author Andrea Camilleri, best known for his novels about Inspector Montalbano that became a popular TV series.

Margherita Hack spent some time in politics and was also an entrepreneur at times. But she had a lot of fun, too. On the panel with Camilleri, the author of the Montalbano stories, they all come out (in unison) with the famous introduction Montalbano sono (Montalbano, I am). Putting the verb at the end is typical of Sicily, where the story takes place. Otherwise, it would be Sono Montalbano (I'm Montalbano) or, on the phone, "This is Montalbano."

We discover that Margherita Hack was a devoted fan of the long-running TV series, Un posto al sole [a place in the sun]. She explains why. Francesca goes back to Trieste and meets up with Eda who talks about having lived in the same house with Margherita Hack.

In this segment, Margherita talks about her choice not to have children and also discusses her position regarding God. She can't prove he exists nor can she prove he doesn't.

Even though Aldo and Margherita were very different in many ways, they came together in their skepticism. Towards the end of her life, Margherita couldn't move around much, but her brain never stopped going.

Margherita left a legacy of progress, both scientific and social. Perhaps she is still looking down on us, since an asteroid was named after her: 8558 Hack.

Matarazzo and Calagiuri hit a dead end in their first encounter at the University of Bari. Imma finally gets to consult the files associated with Bruno's disappearance fifteen years prior. Diana asks her for a favor she shouldn't have.

Imma is back in the office when she gets an unexpected visitor.

Some evidence has been burned in what appears to be a gas leak, and Imma is very concerned for her case against Romaniello. She goes back to her office to fight back when she has two different visitors, one more welcome than the other.

Imma meets her colleagues at the crime scene and recognizes the victim. The marshal of the Pisticci Carabinieri also knew the young woman who apparently had taken her own life.

Imma is offering her condolences to the parents of the victim, while gently questioning them. At the same time, she thinks back to a conversation she had had with Donata.

Grandma and granddaughter prepare a traditional dish from Basilicata, called la ciambotta, a kind of stew with vegetables, and sometimes meat. Valentina serves it to her parents that evening. The next day, Imma and Diana talk about the parliamentarian, Lombardi.

Imma talks to the proprietor of the restaurant where Donata was to try out as a waitress. She also has a more fruitful conversation with an employee. Later on, she takes her mother to the eye doctor, where she gets somewhat of a jolt.

Imma takes her mother to the eye doctor and by chance absorbs some new information about her past. She talks about the Romaniello case with Vitali and lets him know she will be gone for a couple of days.
