Romanzo di una strage is a 2012 Italian historical drama film directed by Marco Tullio Giordana. It is loosely based on the book Il segreto di Piazza Fontana by Paolo Cucchiarelli.
The film deals with the reconstruction of the Piazza Fontana bombing that took place in Milan December 12, 1969, and of the tragic events that ensued, from the death of Giuseppe Pinelli, which occurred in mysterious circumstances during an interrogation, to the death of the Commissioner Luigi Calabresi, who had led the investigation.
