After their trip round the world in 2004, fellow actors and bike fanatics Ewan McGregor and Charley Boorman couldn't shake the travel bug. Inspired by their UNICEF visits to Africa, they knew they had to go back and experience this extraordinary continent in more depth. And so they set off on their 15,000-mile journey with two new BMWs loaded up for the trip. Their route took them from John O'Groats at the northernmost tip of Scotland to Cape Agulhas on the southernmost tip of South Africa. Along the way they rode some of the toughest terrain in the world - and met some of the friendliest people. They rode their bikes right up to the pyramids in Egypt and visited Luke Skywalker's house in Tunisia. They met people who had triumphed over terrifying experiences - former childhood soldiers in Uganda and children living amidst the minefields of Ethiopia.
