Renzo and Camilla have a heated argument after a work dinner that went badly, bringing to the surface tensions and jealousies that put their relationship to the test. Meanwhile, at school, amid subtle romantic hints between colleagues, attention turns to the upcoming assembly.

Mrs. Nubila calmly recounts what actually happened, while the investigators listen, incredulous and shocked.

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.

During the school assembly, the principal surprises the students by revealing his rebellious past and ultimately decides to withdraw the controversial circular. Meanwhile, Anna faces a delicate moment in her life and receives an unexpected dinner invitation.

During the interrogation of the Nubila couple, the circumstances that led to Lara's death come to light. The investigating team can't understand why the baby would have been abandoned, but that, too, becomes clear. All in all, it's very disturbing to everyone in different ways.

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.

The discovery of the body of an unidentified man, called "Quantunque," sets off a complex investigation full of questions. While the police search for new leads, Anna faces the pain of loss and the desire to know the truth about the victim and his tragic fate.
