Tony begins deep in the Arctic Circle. His first stop is at a Polar Park working with wolves on a fascinating but brave project. Tony then rides the Arctic Circle Train south to the town of Kiruna, on the edge of Swedish Lapland, which is undergoing a very unique transformation as it's being moved building by building to a whole new area. Tony also gets to see behind the scenes at the famous Ice Hotel, a structure which is rebuilt every year from ice taken from the nearby Torne river and ends his journey at Miniature Wonderland - the world's largest model railway.
