The story of four friends Giulio, Gemma, Paolo, Riccardo, told over forty years, from 1980 to today, from adolescence to adulthood. Their hopes, their disappointments, their successes and failures are the intertwining of a great story of friendship and love through which Italy and the Italians are also told. A large fresco that tells who we are, where we come from and also where they will go and who our children will be. It is the great circle of life that repeats itself with the same dynamics despite the fact that years and even different periods pass in the background.
