The sturgeon is a species that has inhabited the Po River for over 200 million years. Today its survival is threatened by extensive human activity and the construction of a dam that has disrupted the river's natural flow. The few remaining specimens are kept alive in long artificial basins submerged in the forest, far from any danger, in tranquil water. They await adulthood and being released into the murky waters of the river, at the mercy of their destiny. VIVI shows how short-sighted policies leading to the extinction of an ancient species. It tells the collective story of young researchers and volunteers dedicated to safeguarding life, habitat, and culture, part of their territory. It contrasts the physicality of a wall that obstructs and divides with the apparently fragile but resilient nature. It does so through the eyes of the sturgeon, showing the challenges it must overcome in a corrupted habitat. It's a symphony of water, nature, and small actions that change the world.
