Un metro sotto i pesci is a poetic account of a journey across the Po Delta, a land of unforgettable beauty, a little known area where people live below sea level. The film is also a journey into the past: Florestano Vancini captures the painful metamorphosis of the Delta in the images from documentaries he filmed there 50 years ago. Fishermen, a poet and other unusual characters make up a chorus of figures a mysterious traveller encounters before dissipating in the extraordinary beauty of this landscape.
