Eda discovered Margherita Hack on a TV show hosted by Piero Angela. This changed Eda's life. Margherita as a young scientist had a rough time in a profession where men were the important ones and had little regard for women.

A car problem allows us to meet Eda Gjergo, a young astrophysicist, who will in turn lead us to meet Margherita Hack, the subject of this episode about women luminaries. Hack was a famous scientist, communicator, and activist.

The documentary concludes with some valuable advice from Rita Levi-Montalcini about how to live one's life. People who knew her offer some adjectives to describe who she was.

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.

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.

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.

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.

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.

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.

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 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 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 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.

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.

In August of 2014, the European Space Agency Rosetta probe reached the comet 67/P. This mission allowed for the collection of a great deal of data about comets. In fact, in this episode, a comet will be fashioned out of fairly common ingredients in a normal kitchen. That's pretty exciting.
