On 14 November 1951, after days and weeks of heavy rain in northern Italy, the Veneto area of Polesine was completely submerged by the waters of the Po: in the stretch between Santa Maria Maddalena and Occhiobello, the riverbank gave way, triggering the largest flood in Italy in the 20th century. The course of the Po is devastating, as shown by these 16mm shots by Grisano Vendemiati documenting the flooding in the Corbola and Adria areas. Headmaster of a school in Adria and fervent filmmaker, the 40-year-old Vendemiati, who experienced the war as a soldier and was a prisoner in Germany for a long time, does not lose heart. After sending his wife and children to an uncle's house in Ferrara, and settling in with his elderly mother, who cannot move, he moves around with makeshift vehicles and films the flooding in Adria, the flooded plain, the bridges and houses swamped and partly destroyed. When he can, he portrays the people, the looks, the spontaneous reactions, the first rescues. And then in the days and months that followed the arrival of help and the beginning of reconstruction. All materials that will be edited into this very precious documentary film of which we present the parts about the flood and the arrival of help.
