We have always been used to thinking of the deserts of our planet as places with an infinite horizon but without life. We set off with Alberto Angela for an extraordinary journey around our planet, a journey between horizons that seem infinite, under a blinding sun, listening to the wind, in the company of the sound of silence. We explore enchanted landscapes where nothing and no one can stand still. It turns out that in the desert everything moves, the sand, the animals, the plants. And especially men.
