Hugh Dennis and Julia Bradbury are in the Highlands of Scotland, Britain's wildest and oldest landscape. In this remote and magnificent part of the country, they explore a landscape built by volcanoes, earthquakes and ice, and discover how this dramatic past lives on today. Hugh takes a breath-taking ride across Loch Ness as he uncovers how the deepest lake in Britain set the stage for a British sporting hero; and he reveals the astonishing story of how the ancient, ice-carved shape of the Highlands helped win the Battle of Britain. Julia takes to the air in an adventurous seaplane ride, to find clues to the Highlands turbulent past. She discovers the strange tale of an earthquake-shaken Highland village, and attempts to set off an ancient earthquake recorder using gunpowder. For a country our size, Britain has the biggest variety of geology on earth, which has created not only a beautiful landscape, but also a fascinating industrial heritage, a rich history and many legends. Hugh and Julia are a pair well met. Hugh has been obsessed by the shape of the landscape, and how it formed, since he was a child and he went on to study it as part of his Cambridge degree. And Julia has loved walking the British countryside since she could toddle.
