DIA 1991 shows the operations of the Italian Animafia Investigative Direction as told by the actual police officers that ran them: 4 different stories, 10 narrators, and the memories of judge Giovanni Falcone kept alive by his close friend, magistrate Giuseppe Ayala. Thanks to RAI’s archival footage, cities marked by organised crime during the nineties live again on screen. But now viewed through the eyes of the field agents that were brought back there, where history took place.
