Caterina is the 13-year-old only child of Giancarlo, an aspiring novelist and teacher of accounting at a country school. In spite of his often lucid assessments of modern society, Giancarlo is a typically burned-out teacher whom his job has imbued with bitterness and social resentment, with a sheer lack of perspective concerning human relations, and with an overbearing, holier-than-thou demeanor that is a major plot point throughout the movie.
He relocates his daughter Caterina and his timid, long-suffering wife Agata to his birthplace, Rome, after finally secured a long-coveted teaching position. The family settles in Giancarlo's former district, where he reconnects with his neighbor and childhood friend, Fabietto. Once settled in the Italian capital, Caterina enrolls in a fast-track high school. She immediately finds herself pulled between two competing student cliques: a leftist bohemian contingent headed by Margherita and a right-leaning group headed by Daniela. Both clique leaders come from socially prominent families. Margherita's mother is a noted intellectual and political writer. Daniela's father is a government minister.
