Wilfred Thesiger was one of Britain's great explorers and writers. His greatest journeys were through the world's largest sand desert: the Empty Quarter of the Arabian Peninsula. Inspired by their hero, adventurers Alastair Humphreys and Leon McCarron attempt a journey of their own into the Empty Quarter. Their trip is hastily-planned and low budget: unable to afford camels they instead hope to drag a homemade steel cart (filled with 300kg of supplies) through the ferocious desert heat. This film is their story.
