Program about historical dissemination, presented by Paolo Mieli. Each episode sees a historian interacting with the presenter and three young university students.

After the World War I, Mussolini's perspective on life is severely altered; once a willful socialist reformer, now obsessed with the idea of power, he founds the National Fascist Party in 1921 and assumes political power in 1922, becoming the Duce, dictator of Italy. His success encourages Hitler to take power in Germany in 1933, opening the dark road to World War II. (Originally released as a two-part miniseries. Includes colorized archival footage.)
