A middle-class Italian family is tore apart when the father meets an old flame, the mother—a frustrated onetime actress—auditions for a play, their insecure son tries to make friends through drugs, and their underaged daughter—who has already figured out how to use sex to her advantage—does what she does best to appear on TV.

Giulia and Carlo have been happy together for three years, but Giulia's announcement that she is pregnant sends him into a secret panic. Terrified at his imminent entry into the adult world of irreversible responsibilities, Carlo finds himself tempted by a bewitching 18-year-old girl, Francesca, whom he meets by chance at a wedding. The possibility of one last youthful crazy fling before the impending prison of parenthood proves to be too attractive to resist.
