What is the future of the longest river in Italy? A journalist and a filmmaker embark on a cycling trip along the Po River, driven by the desire to understand how much climate change and human intervention are affecting its waters. The result is a story of a river forgotten by the state authorities who realize its existence only during its floods. A river that over the years is changing from a hydrogeological point of view and that serves as a sentinel on climate change in progress. Official Selections 2021: Smaragdni Eco Film Festival, CinemAmbiente Environmental Film Festival.
