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.

After the concert, the students' families find themselves facing separations, changes, and difficult truths to accept. Rosario's refusal to leave Milan, Matteo's pain over his mother's absence, and the adults' attempts to protect him bring to the surface tensions, vulnerabilities, and a deep need for affection and stability.
