The magical Frasassi caves look like something out of a fairy tale, but there's a more scientific explanation.

Alberto Angela describes the discovery of the Ancona Abyss, named after the city the speleologists were from. It’s part of the Great Wind Cave.

Alberto Angela tells us how these natural wonders were discovered by a group of young cave explorers from the nearby city of Ancona.

Alberto Angela brings us to the Ancona Abyss, an immense cave chamber in the Natural Regional Park of Gola della Rossa and Frasassi in the Marches region. The spectacular Ancona Abyss and other innermost caves in the Frasassi cave system were only discovered in 1971.

Nature offers us some extraordinary wonders, and this time, Alberto Angela takes us to the Frassassi Caves, in the Marches region, and explains what the caves were used for by prehistoric man.

The episode closes with one of Domenico Modugno's most famous songs, Tu si' 'na cosa grande (you are something great to me), as Mimmo muses about the present and the future.

Mimmo goes to Paris and hears some great music, but doesn't have much success with his songs. That leaves him little choice but to go to Canada. It's cold there! He keeps in touch with Franca during his travels.

When they get to his hometown, there's one person Mimmo doesn't want to see and one person he does want to see. Later on, he talks to Franca about how frustrated he is about his career.

As Mimmo and Franca enjoy the beach and swimming in the clear water, he tells her about his childhood in the town they can see from where they are sitting.

Franca, disappointed and hurt, goes to visit her grandmother in Sicily and writes a letter to Mimmo.

Before the prince leaves the gathering in a very melancholy mood, he tells Mimmo about a job. Mimmo gets the job, but has a hard time satisfying the director (who is a bit eccentric, it must be said). Franca comes to the theater to see Mimmo at a certain point, but it might not have been the right moment.

Carolina Raspanti plays Dafne, a girl of 35 who leads a regular life until she loses her mother and has to take care of her father suffering from depression. Dafne has Down syndrome, as does the actress who portrays her.

At their meeting with the head of Curci music publishers in Milan, Riccardo and Mimmo dare to mention the word "contract." Once back in Rome, the Prince shows up at the artists' circle where Mimmo is having dinner.

Franca's career is going nicely, and Mimmo decides that he'll do whatever they want him to: Sing, dance, act...
