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.

As a child, Rita Levi Montalcini was shy and insecure. Her father wanted her to get married and have children, but she had other plans for her life. She also had a twin sister who was an artist.

Rita Levi Montalcini was a strong proponent of education and instruction as the means to gain freedom. She was also an example of it. This segment describes a visit to women in prison, and the obstacles Montalcini had to face, as a woman and as a Jew, during the Nazi-Fascist regime.

Because of the racial laws in Italy during the period of Fascism, many Jews left the country, including Rita Levi Montalcini. In Italy she wasn't allowed to work or publish papers, but somehow, she found a way to keep going.

The formal, ceremonious aspect of the Nobel Prize awards was not what Rita Levi-Montalcini was used to, but she used that recognition to her advantage. Winning the Nobel Prize wasn't necessarily the high point in her career.

Rita Levi Montalcini doesn't feel like she made any sacrifices in her life, including not having a family. She had a clear vision of what she wanted out of life, and she followed it.

After winning the Nobel prize, Rita Levi-Montalcini was not as shy as she had been prior to that moment. Because she stood out as a woman in a "man's world," she was able to use her unique position to make her mark, not only in the science world, but in society.

Not only did she win a Nobel prize; in her own country, she was appointed as a Senator for life, a great honor. But she took that job seriously and participated actively and with integrity. Not everyone appreciated that.

In her final years, Rita Levi-Montalci was very, very frail, but she never lost her combative spirit. Romano Prodi recalls the last time he saw her.
