You can't get there from here

An international team of 4 friends undertake the Plymouth to Dakar Challenge a ‘banger rally’ which annually shadows the route of the Paris Dakar Rally. They acquire two old Mercedes vans and take a 3 week route through Spain, Morocco, Western Sahara, Mauritania, Senegal and Gambia. They arrange to transport prosthetic limbs for a Bristol based charity to a clinic in Gambia providing help to amputees. Interviewing a number of experts on the 30 year conflict between Morocco and the Saharawi natives, they arrange to meet with Saharawi ‘dissidents’ in the Western Sahara to expose their oppression by Moroccan authorities who they claim are occupying their land and profiting from their national resources.
