Charley embarks on another epic journey, this time exploring America. He begins by exploring the lava fields of Hawaii Island and then taking to the waters off Waikiki Beach in an outrigger canoe. Charley then heads north to Alaska, where he tries to fulfil a boyhood dream of building an igloo, before sampling life on the high seas when he boards a 100-year-old schooner for a trip off the Atlantic coast

Charley rides his motorcycle to North Carolina, where he takes to the air in a replica of the Wright brothers' historic biplane and dives to the wreck of a First World War U-boat scuttled by the Germans when they realised the war was lost. In Charlotte, he learns about the War of Independence and gets to grips with firing a traditional musket, before heading to the Chattooga River in South Carolina, the location where his father John filmed 1972 thriller Deliverance

Charley heads to Walker County in Georgia and goes potholing with the local fire department's rescue team, before making the eight-hour ride to Mississippi to find out about the logging industry around the state's great river. Charley then rides down to Louisiana to discover more about the formation of modern America in New Orleans, before being taught the art of catching frogs in the swamps of Lafayette. He then tries rodeo-riding at a ranch in Texas and ends this leg of his journey in New Mexico

Charley sets off on the final leg of his journey, scaling a cliff in Colorado before visiting a soda ash mine in Wyoming. He then heads to the Bonneville Salt Flats in Utah and joins Erin Hunter and Andy Sills in an attempt to set a world speed record for three people on one motorbike, and then rides through a surprisingly wet Death Valley in California. Charley eventually reaches the Pacific coast, where a large convoy of like-minded bikers join him on the ride into his final destination of Los Angeles
