2. London to Volgograd

Travelling through Europe, Ewan McGregor and Charley Boorman head for Slovakia, but the lads' motorbike odyssey is about to hit trouble. Originals of their vehicle-ownership documents are essential (their photocopies won't do); once that's sorted, Charley accidentally sprays Ewan in the eyes with petrol! A visit to a coal mine is followed by a short hop into Russia and a trip on board a ferry heading for Kazakhstan.
