Comedians Rhod Gilbert and Greg Davies attempt to drive through the mountainous, landlocked nation of Nepal. Starting from the chaotic border with India, they travel across the country's most important roads, from highways that maintain its cities to freshly-dug dirt tracks that connect to isolated communities.

After days of swerving overloaded buses, dodging trucks and clinging to crumbling mountain roads, disaster strikes within sight of their final destination.
