"I cento passi" (one hundred steps) was the distance between the Impastatos' house and the house of Tano Badalamenti, an important Mafia boss, in the small Sicilian town of Cinisi. The movie is the story of Peppino Impastato, a young left-wing activist that in the late seventies (when almost nobody dared to speak about Mafia, and several politicians maintained that Mafia did not even exist) repeatedly denounced Badalamenti crimes and the whole Mafia system using a small local radio station, with the arm of irony. In 1978 Peppino (30 years old) was killed by an explosion. The police archived the case as an accident or a suicide, but his friends never accepted this thesis. Note: This is a true story. More than wenty years after Peppino's death, the case has been re-opened. Tano Badalamenti, meanwhile, has been convicted in USA for drug traffic.
