In Rome it hasn’t rained for three years and the lack of water is overturning rules and habits. Through the city dying of thirst and prohibitions moves a chorus of people, young and old, marginalised and successful, victims and profiteers. Their lives are linked in a single design, while each seeks his or her deliverance.

Rome, 1990. The night Italy's national football team is eliminated from the World Cup by Argentina on penalty kicks, a well-known film producer is found dead in the Tiber river. The main suspects for the murder are three young aspiring screenwriters, who–promptly taken to the police–start to tell their version of the story.

Palermo, Sicily, 1984. Examining magistrate Giovanni Falcone allies with Tomasso Buscetta, a former mobster, to defeat the clan of Corleone, the ruthless Mafia faction that rules Cosa Nostra with an iron hand, cruelly eliminating all those who dare to oppose its immense power: other criminals, policemen, judges, even innocent civilians. One of them wants revenge, the other wants justice. But only one can survive such an unequal fight.
