In 1930 Omani Sheikh Saleh bin Khalut and Englishman Bertram Thomas made the first recorded crossing of the Rub Al Khali, the Empty Quarter—the vast, arid wilderness at the heart of Arabia. Now three men, two Omani explorers and a Briton, take on the challenge to recreate that journey and walk from Salalah in Oman to Doha in Qatar—a journey of more than 1,000 kilometers across one of the most dangerous places in the world. In this terrifying challenge they battle over giant dunes and through vicious sandstorms, searching constantly for wells as their water supplies run dangerously low. Can they make it, or will sickness, fatigue and injury defeat them? Their struggle is an inspirational story of courage and determination.
