Jeremy Clarkson, Richard Hammond, and James May travel to Vietnam and are told to travel the entire length of the country in just eight days, thereby achieving what the American military failed to do in ten years. But first they must each buy suitable transport for the trip. Despite having several million Dong in their pockets, this proves to be rather less money than they thought - especially in one of the most expensive car markets in the world. Nevertheless, the boys are resourceful, and with the wheels eventually sorted, they set off on one of the most spectacular and incredible road trips Top Gear has ever attempted.
