Former British Army Captain and explorer Ed Stafford goes on a journey around the world to uncover some riddles. Photographs showing unexplained and unusual markings in remote locations on Earth have been taken from the International Space Station and spy satellites. Ed's aim is to look up these locations and use his expertise of travelling in difficult climates and extreme terrain to get to those areas and discover what is causing these mysterious patterns. The adventurer makes it to distant lands in West Papua, where photographs are displaying huge white lines, and over in the Danakil Desert the truth behind strange circular dots on the land is discovered.
