After finding a suitable base Ewan and Charley spend several months in London prior to departure, planning a route. Eve, Ewan's wife, decides she would like to join part of the trip. Ewan is over the moon but Charley's not so sure as she's never ridden a bike before. Meanwhile, as part of their training, the team attends a hostile environment course where they are faced with the kind of difficulties and dangers they may encounter in Africa. Two months before departure, Ewan has an accident and breaks his leg jeopardizing the future of the trip. As the departure date looms worryingly the team still doesn't have their visas for Libya. Six have been promised, but for David and Jimmy, the two Americans on the crew, it's not looking promising. The team take their vehicles and make their way up to John O'Groats at the most Northerly point of Scotland to start this epic adventure and what will be a journey of a lifetime.
