Eighteen countries. Fifteen thousand miles. Two bikers. One amazing adventure...

After their fantastic trip round the world in 2004, Ewan McGregor and Charley Boorman couldn't shake the travel bug. Inspired by their UNICEF visit 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 adventure, experiencing some of the toughest terrain in the world - and meeting some of the friendliest people.

Riding through spectacular scenery, often in extreme temperatures, Ewan and Charley faced their hardest challenge yet. With their trademark humour and honesty they tell their story - the drama, the dangers and the sheer exhileraton of riding together again, through a continent filled with magic and wonder.
