A taut, cerebral crime drama, part thriller and part procedural, Piazza Fontana follows the investigation into the real-life 1969 terrorist bombing of the headquarters of the National Agrarian Bank at the Piazza Fontana in Milan. Valerio Mastandrea plays police chief Luigi Calabresi, who must unravel the chaotic web of politics and ideologies in conflict just beneath the surface of Italian society. As Calabresi moves closer to the truth, the danger to his career and to his life likewise advance. Keeping the temperature of the film cool and the tension at a constant simmer, director Marco Tullio Giordana is far more interested in the political complexities and lingering ambiguities of the historic crime than in easy titillation or suspense, yet the crisp tempo and sharp construction leave no audience member behind.
