After being kicked out of Marioni's class, Matteo returns home where his uncle is waiting to introduce him to Lorenzo. Matteo goes out with Domenico who tells him something about Marioni. Meanwhile, something has happened in the group chat.

Matteo is about to leave the rehearsals with Marioni after their argument. Irene arrives in the audience, having learned about the warning and wants to be close to Luca. He asks her to stay with him but she doesn't seem convinced.

Matteo stays to practice alone with Marioni, who encourages him to play without sheet music and follow his commands, but Matteo mentions Giacomo and the lesson ends.

Sara offers to walk Chiara home when Marioni discovers her, and the girl tells little Chiara that she hasn't always been blind. There are things she remembers and things she misses. At the end of rehearsal, Marioni criticizes the orchestra.

Marioni is summoned by the principal because he received a warning from Giacomo's parents who hold him responsible for what happened to their son. During rehearsals, the maestro discovers someone who shouldn't be in the hall.

Matteo meets Sofia to whom he confesses being excited about the concert. At Sara's house, Gigi plays for her parents the song he composed for her. Robbo and Chiara unfortunately witness an argument between their parents.

Matteo and his uncle seem to be very similar when it comes to feelings, and perhaps uncle Daniele isn't so happy about it. Scheggia and Sofia go to eat at her mother's restaurant and tease her a bit.

During the concert rehearsals, Marioni believes that Barbara hasn't put in enough effort because she has dedicated time to studying philosophy. He therefore decides to exclude her and warns the others if they try to console her.

Sara goes to talk to Gigi and invites him to her house to talk but another time because tonight she's with her friends. When Robbo returns home, he finds Chiara upset, who tells him she's gotten into trouble. Barbara, on the other hand, has to face Marioni again in class.

Maestro Marioni listens to Domenico and Barbara play and doesn't spare harsh treatment towards the girl. Despite her friends being supportive of her, Barbara decides to go home to study instead of going out after rehearsal.

Irene tries to convince Luca to leave with her after finding out that he saw Giacomo in front of the school. Meanwhile, the kids continue with their concert rehearsals.

After the meeting with the doctor, Matteo meets his uncle who invites him for an aperitif. At the venue, they are served by his uncle's ex and Matteo teases him about it.

Marioni manages to reach Giacomo to tell him that he's sorry for how things turned out but also to encourage him to move on with his life. Matteo goes to talk to the new psychologist but puts up his defenses by saying that he doesn't talk much.

After Marioni assigns the orchestra parts to play in front of Fiore, moments of nervousness arise among the students. However, at the conservatory exit, the scene that creates the most tension is an unexpected return.

Maestro Ruggero Fiore, who has conducted in the most important theaters in the world, will arrive at the conservatory. Professor Marioni defines and assigns the roles of each musician within the orchestra, but not everyone is happy.
