Piazza Fontana: The Italian Conspiracy (movie, 2012)

On December 12, 1969, a bomb kills 17 people and injures many more at a major national bank in Milan. Others bombings soon follow, marking the beginning of the Years of Lead. Local anarchists are scapegoated for the massacre by police and the media, but an investigator uncovers a larger subversive project made of far-right fringe groups, corrupt secret services, and other interests that seek to undermine democracy.
