[5][6] Dante Balestra is the new philosophy teacher at the Leonardo da Vinci scientific high school in Rome, where he has returned after an eight-year absence to be with his son, Simone, now that Floriana, his ex-wife, is moving to Glasgow.

Charming and unconventional, the professor takes a class at the Leonardo Da Vinci High School where he applies his non-conformist teaching method and establishes a very special relationship with his pupils, including Simone himself.

The beating heart of the series remains the Leonardo Da Vinci high school with the class attended by Simone and Manuel (Anita's son) where Dante, with his usual non-conformist and ingenious flair, uses philosophy to help the boys solve their problems, including complicated love affairs, intrusive parents, daydreams and dashed hopes.

New class members appear in this season, such as Nina, a girl of Polish origin who hides a complicated life path, Rayan, a promising footballer who has arrived from Africa and is more interested in football than in studying, Viola, a disabled girl with an impossible character, and finally Mimmo, a former student of Dante's who ended up in juvenile prison, whom the professor has managed to get committed to the Leonardo da Vinci library in semi-freedom.
