Comedians Rhod Gilbert and Greg Davies attempt to drive through the mountainous, landlocked nation of Nepal. They travel across the country's most important roads; from highways that maintain its cities to dirt tracks connecting to isolated communities.

Adventurer Ben Fogle and comedian Hugh Dennis drive a historic route from the Peruvian Andes to the Amazon depths. It's a ride made up of 2,000 ft drops and hairpin bends on dirt roads, stretching from mountains high above the clouds to jungle trails.
