We built the world around us with horsepower. But what is it that makes humans and horses so perfect for each other?

Over three spectacular hours of cutting-edge science and gripping adventure, Thompson explores the evolution of horsepower, discovers how our ancestors tamed the horse and learns fascinating new insights into the body and mind of this unique animal. Thompson goes on a global adventure of discovery, living and riding with horse nomads in Arabia, Siberia and Mongolia, travelling into the field with archeologists, geneticists, and horse psychologists, and above all, getting friendly with horses everywhere he goes.
