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.
