During the rehearsal in the hall, tensions emerge between some members of the orchestra. Domenico misunderstands the relationship between Sara and Matteo, while the rehearsal continues amid errors, nervousness and arguments between the musicians. The maestro, focused on the music, ignores the chaos that builds around him.

Rosario claims he no longer worries about the consequences of his actions, because he will have to leave Milan anyway. Meanwhile, Domenico and Matteo clash harshly, calling their friendship into question amid accusations and betrayals. Sara is forced to confront a difficult reality, understanding that she must grow up quickly and put her emotional strength to the test.

Matteo gets home and walks in on his uncle and Daniele, the neighbor. After Daniele leaves, Matteo talks to his uncle about his personal problems, wondering why he is behaving so badly.

Barbara avoids a meeting to take refuge in music, while the rest of the group confronts insecurities. A breathing crisis of little Chiara brings past fears back to light, but also the strength of mutual support. Meanwhile, among colleagues, the organization of an innovative concert takes shape.

Irene is not so sure Marioni's car crash was really an accident, and the two talk frankly. Meanwhile, Robbo's sister Chiara has an asthma attack, and Robbo calls their father.

Marioni has an intimate moment with Irene and lets her know how important she is to him, whispering the lyrics to "Senza fine" by Gino Paoli. At the conservatory, the orchestra is ready to go onstage for the concert, where, presumably, everyone will play from memory. Matteo's uncle and friend are in the audience, but Nathan hasn't invited anyone. Sara is nervous.

Marioni introduces an unusual concert, in which he gives up conducting the orchestra to accommodate a visually impaired musician. The orchestra is arranged among the audience, and the musicians will perform without visual references, relying exclusively on their ears.

With the lights dimmed, the conservatory orchestra gives a moving performance of the famous piece known as Adagio di Albinoni. As they play, Marioni listens, and his emotions take him back in time to relive his daughter's bicycle accident and aftermath.

The evening is a huge success, but not everyone is elated. Marioni has come to the conclusion that his daughter's death was his fault, Matteo's uncle has a somewhat disturbing conversation with one of Matteo's schoolmates, and Domenico tries to talk to Barbara.

Alice introduces us to her group of friends. They've called themselves "JAMS" and we find out why in this episode. She begins telling us the story of how they got to know one another. Alice talks about la prima media. This is equivalent to the first year of middle school or the 6th grade of elementary school. The kids are about 11 or 12 years old.

It's the first day of school for our friends. In fact, it's their first year of middle school. The desks are set up for pairs of pupils, so choices have to be made as to where to sit and whom to share a desk with.

The class is welcomed by the principal as well as the art teacher. The surprise is that there will be a cooking course twice a week, as well as a group cooking contest. Who's on board? As we know, Joy is enthusiastic about it, but what about the others?

Alice, Joy, and Max want to win the contest, so they go around the neighborhood to find some traditional recipes. One stop they make is at the home of Joy's father's friend. The three classmates meet up with Stefano more than once, making them curious.

At the park, the kids try to come up with a recipe and they invite Stefano to take part in the project. One thing leads to another.

Joy has an interesting idea about where they can practice cooking. But it's a bigger challenge than she expected.
