Vittorio De Sica, along with other filmmakers and actors, does not want to be transferred to Venice, as has been mandated by the State. There, he would have to shoot propaganda movies for the Fascists. Luckily a Catholic film company wants to make a movie about a train of sick and deformed people on their way to seek miracles at the shrine of Our Lady of Loreto, a popular pilgrimage destination in the Marches region. The kind of train that carries pilgrims is called un treno bianco (a white train).

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.

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.

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.

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.

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.

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.
