November 14, 1951, the left bank of the Po river a few hundred meters from the Padua-Bologna railway bridge breaks. The tide invades the Polesine's lands in a few minutes, one of the poorest regions in Italy at the time. Thousands people, men, women and children flee while the water remains stagnant for months between the houses and the countryside. Today, 70 years later, the children of that time remember those months immortalized by the films perfectly preserved in the Istituto Luce's archives.
