In a special episode, Jeremy Clarkson, Richard Hammond and James May are dropped in the vast wilderness of Mongolia and told to await a delivery which turns out to be some basic rations and all the flat-packed parts they need to assemble a vehicle in which they can escape to civilisation. Navigating their way out of this epic, enormous and completely people-free terrain is going to be hard enough, especially with only a few days’ worth of food and clean water to see them through, but first they’ve got to build an entire car, and one of the ‘engineers’ is the world’s most ham-fisted hammer enthusiast.
