In an adventure of a lifetime, Alexander Armstrong heads north in to an ever more hostile Arctic winter to explore the farthest reaches of the globe. In an epic journey, he navigates some of the Earth's toughest terrain, first travelling through the glittering landscape of Scandinavia, then on to the isolated islands of Iceland and Greenland, as far as the infamously impassable Northwest Passage. His final frontier is Canada and Alaska, where his journey ends on the international dateline between the USA and Russia.
