Every summer, the world's top motocross racers come together for the grueling 12-race AMA Outdoor Motocross Championship Series to battle the heat, the tracks, and each other. Some come cocky, others come humble. Some bring family, while others bring their entourage. They are determined. Dedicated. They know that there's only one winner in the most demanding action sport in the world. He will be the racer with the most intensity, consistency, and desire...in an arena where boys become warriors. We enter this mysterious underworld to unravel the hidden lives of MX professionals; from the planet's top riders, to upcoming rookies, to the trainers and mechanics who hold them up, to the families and friends that serve as their foundation. We follow their nomadic journey on the road, on the track, under the tent, and in all-weather to uncover the lives of men who compete for a living; hostile rivalries, brutal tracks, and a constant goal of mastering their body's limitations. In this world, everything comes second to The Moto. The Cast includes Ryan Villopoto, Mike Alessi, Josh Grant, Ryan Dungey, Blake Wharton, Tommy Searle, Tyla Rattray, Chad Reed and Andrew Short.
