Imma goes to the hospital and can't help looking at Pietro's phone while he is sleeping. Back at the office, Diana is in tears because her husband wants a separation.

Imma is talking with Mottola to find any connections with Don Mariano's death. He is accusing the deceased of not having helped him, and at a certain point, she says: Ma si rende conto? (but do you have any idea?) For more on this expression see our lesson. Back home, Imma is irritable, but she can't talk to her daughter about the real reasons she is upset.

Since the phone records have arrived, Imma must provide explanations to both Vitali and Calogiuri. Both are of the opinion that Imma doesn't trust them.

While discussing the murder case with Calogiuri, Imma learns about a violent husband, a certain Pasquale Iannuzzi. Imma goes to see Pietro in the hospital and questions him, as she knows how to do very well.

Calogiuri is sharing useful information with Imma to discover something about Don Mariano's death when Diana enters to communicate that she has found what Imma had asked her to look for.

Imma and Calogiuri compare notes on what they have regarding the investigation into Don Mariano's death. The two disagree on how to proceed to the point of losing their patience.

Imma spends some time with Pietro in the hospital, but once she leaves, she is determined to figure out what the keys found with Don Mariano open, and she goes to ask someone who might know.

At the funeral, Valentina meets a young man who had followed her recipe page and says he cared deeply for Don Mariano. Calogiuri visits Iannuzzi's wife and later, with Imma, speaks again with Iannuzzi.

Iannuzzi is interrogated again and, in front of his wife, has an outburst of anger that makes him confess what he has done. Despite everything, Imma still doesn't believe what he's saying.

Imma asks a favor of a friend even though the case is no longer hers. Pietro returns home and Valentina is on cloud nine. Imma, on the other hand, continues to scold her husband about what he can't do due to his convalescence.

Comedian and actor Caterina Guzzanti is a guest at a middle school in Afragola, in the province of Naples, a school named after Rita Levi Montalcini. Guzzanti meets with the students from the theater class for a lesson on the imagination, which has a lot of importance in her work but was also very important to the great researcher from Turin, Montalcini.

Rita Levi Montalcini talks about when she won the Nobel Prize in 1986. Her niece, Piera, tells the story from her point of view, and Paola Tarassi, a research student of hers, tells about studying with her after she had already won the Nobel.

Rita Levi Montalcini felt that imagination was the "secret sauce" of her research. And this encouraged her to turn to young people, who have plenty of imagination. She didn't hesitate to teach kids of junior high school age, which came as a surprise to some people, since she was a winner of the Nobel prize.

Rita Levi Montalcini dedicated a great part of her life to young people, especially young researchers, and though she had no children of her own, she felt that all kinds of young people were like sons and daughters to her.

Rita Levi Montalcini talks about what, as a little girl, she wanted to be when she grew up. One of her main goals was to help women, especially ones from poor countries, become what they were meant to become.
