Beneath the America we think we know lies a nation hidden from view - a nomadic nation, living on the roads, the rails and in the wild open spaces. In its deserts, forests, mountain ranges and on the plains, a huge population of modern nomads pursues its version of the American dream - to live free from the world of careers, mortgages and the white picket fence. When British writer Richard Grant moved to the USA more than 20 years ago it wasn't just a change of country. He soon found himself in a world of travellers and the culture of roadside America - existing alongside, but separate from, conventional society. In this film he takes to the road again, on a journey without destination. In a series of encounters and unplanned meetings, Richard is guided by his own instincts and experiences - and the serendipity of the road. Travelling with loners and groups, he encounters the different 'tribes' of nomads as he journeys across the deserts of America's south west.
