1945, Lake Como. Mussolini and his mistress are captured and shot by local partisans. The precise circumstances of Il Duce’s death remain shrouded in confusion and controversy. 1992, Milan. Colonna takes a job at a fledgling newspaper financed by a powerful media magnate. There he learns the paranoid theories of Braggadocio, who is convinced that Mussolini’s corpse was a body-double and part of a wider Fascist plot. Colonna is sceptical. But when a body is found, stabbed to death in a back alley, and the paper is shut down, even he is jolted out of his complacency. Fuelled by conspiracy theories, Mafiosi, love, corruption and murder, Numero Zero reverberates with the clash of forces that have shaped Italy since the Second World War.
