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.

Manara and his team are still looking for the hit-and-run driver who killed the tramp, and investigating the vineyard owner's disappearance. Lara gives Manara a clue as to why she's still angry with him.

Manara makes an important and unexpected announcement to his colleagues, but gets interrupted by some disturbing news about the town psychic.

Interrogating the wife of one's boss might be cause for some nervousness, but Manara seems to enjoy it. And Luca also has some news, which slips out very casually.

At police headquarters, everyone is thinking about what they will do when they get off work, but then there is a phone call that changes everyone's plans. A fall onto the rocks by the beach, a book with an intriguing design, and we're off to a new episode with Luca Manara.

The investigation begins. Manara and Rivera go to see the victim's wife, while Toscani calls a tow truck. Then all hell breaks loose in a house nearby, where there's been a gas leak.

The autopsy report comes, and Manara goes to talk to the victim's widow. Marta goes to talk to his lover. Marta gets a phone call, and her colleagues realize, with surprise, who her father is.

Both the victim's wife and his lover are questioned at the same time, one by Luca, and one by Marta. Each has a very different memory of what Fello was like.

How good of a painter was the victim? Not all the people who knew him have the same opinion. Luca and Toscani go to see the picture framer and learn a few things.
