Our narrator describes what it was like working on the set of La porta del cielo (the Gates of Heaven): the extras, the dangers, the boredom, and the strategies for keeping the cast and crew safe. He also explains how they reconstructed the railway carriages that are featured so prominently in the film.

Margherita Hack made her mark on the University of Trieste, teaching Astronomy there for almost 30 years and linking it with the Observatory. She had to use some drastic means to be recognized, however, being a woman in a man's world. But the balance changed over time, with her help, to involve many more women than before, both as students and researchers.

To recreate the environment of the San Loreto church, the Basilica of St Paul's Outside the Walls was used for the final scene of the film. The crew was accustomed to working in a non-religious setting where they could do as they liked, so it was a full-time job trying to keep their bad habits (such as smoking) in check so they wouldn't get kicked out by their hosts.

Margherita was much more interested in substance and knowledge than in material things, including physical appearance, and this became her brand, in a certain sense. That didn't keep people from loving and respecting her, although there were some occasional incidents, a few of which are recounted by people who knew her.

During the filming of Heaven's Gate, there were some dicey moments where De Sica had to deal with the German troops and needed all his wits about him. At the same time his crew was cooped up in the basilica and didn't always behave as they should — in fact, tutt'altro (anything but). The narrator also mentions an anecdotal story Fellini told about his experience with the Germans.

Perhaps not everyone knows that Margherita Hack as a girl was quite the athlete. Her sport was track and field. She also had a passion for cycling and rode her bike well into her seventies.

Actors, including Alberto Sordi, who were performing at the Quattro Fontane (four fountains) theater on the fateful day of 23 March 1944 are in danger of being caught by the Germans. During the filming of his movie, De Sica leaves the safety of the basilica just once and is caught and questioned by a Nazi General about why the film is taking so long to be shot.

Although as an athlete, Margherita did make some compromises she felt she had to during the decades of Italian Fascism, she also took a stand against it, risking expulsion from school.

The general hands De Sica a letter from Goebbels himself but since De Sica can't read German, it is translated for him ad alta voce (out loud). It's an invitation to Venice, which De Sica does not want to accept.

This segment recounts how Aldo De Rosa and Margherita met in a park in Florence as kids and later married. Aldo supported her in her scientific work throughout their marriage, which lasted over seventy years.

Vittorio De Sica put himself on the line in order to save his cast and crew, and the film he was making. This final segment describes how he managed to complete La porta del cielo (The Gates of Heaven). The song we hear at the end of this documentary is very famous and was sung by Vittorio De Sica himself for the movie Gli uomini, che mascalzoni... in which he acted. Listen to the entire song here.

Aldo and Margherita stuck together. He might get bored at her lectures, but he would always be there. They both shared a love for sports and motocycles.

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."
