Dos desafortunados técnicos de TV se topan con la escena de un asesinato. Desde entonces, cada paso que dan para evitar ser sospechosos... los hunde en mayores problemas.

January 6, 1980. The President of the Sicilian Region Piersanti Mattarella is going to Mass with his family. A young man approaches the car window and shoots Piersanti in cold blood and kills him. Despite the confusion of the moment with a series of misdirections towards left-wing terrorism, the crime appeared anomalous in its modalities. The young Deputy Prosecutor on duty, that day of the Epiphany, will be Pietro Grasso, future Anti-Mafia Prosecutor and President of the Senate. The investigations will be continued by the Instructor Judge Giovanni Falcone, who will uncover dangerous relationships between the Mafia, Politics, Nar and neo-fascists, the Magliana gang, Gladio and Secret Services.
