The narrative wanders through Rosi’s films, not in the order they were shot but following the chronology of the historical facts they deal with. The documentary therefore not only narrates Rosi’s work, but also portrays half a century of Italian history.

Until the 1970s, Italian cinema dominated the international scene, even competing with Hollywood. Then, in just a few years, came its rapid decline, the flight of our greatest producers, a crisis among the best writer-directors, the collapse of production. But what are the true causes and circumstances of this decline? In an attempt to provide an answer to this question, Di Me Cosa Ne Sai strives to depict this great cultural change. Begun as a loving examination of Italian cinema, the film transformed into a docu-drama that alternates between interviews with the great names of the past and fragments of cultural and political life of the last 30 years. It is a travel diary that shows Italy from north to south, through movie theatres; television-addicted kids; Berlusconi and Fellini; shopping centers; TV news editors; stories of impassioned film exhibitors and directors who fight for their films; and interviews with itinerant projectionists and great European directors.
