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.
