Who is the mysterious stranger Cecilia met on the street? Why is he suspicious of everyone? She is happily married, has a lovely child and a good job: yet she decides to join him and to become his lover, sharing his destiny right up to its tragic conclusion.

With her father on trial, 15-year-old Mignon leaves Paris to stay with her Italian relatives. The rather prim, snooty teen at first struggles to fit in with the more earthy Forbicioni family, each with their own problems. Eventually she bonds with her lovestruck little cousin Giorgio—who'll learn important life lessons over the course of his summer with Mignon.
