Following the success of his previous two expeditions across Canada and South Africa, Charley is back on his bike and this time he is taking on one of the most spectacular countries in the world - The United States of America. Travelling alongside fellow adventurer and director Russ Malkin, this series follows the pair from the volcanic infernos of Hawaii to the icy peaks of Alaska, and then from east to west as they venture off the beaten track to go in search of extreme adventures in the wilderness. This is a journey that tests Charley to the max as he is confronted with some of the most spine tingling challenges he has ever faced. The high risks and low margins for error bring out Charley's humor and the camaraderie he has with those who often hold his life in their hands. Prepare for a rollicking roller coaster of a ride as Charley Boorman experiences wild and extreme America.
