Olympic champions Jayne Torvill and Christopher Dean travel to Alaska on an extraordinary quest to fulfill a lifelong dream of skating in the great outdoors. But luck is against them — in Alaska's hottest year on record there is not a lot of ice to be found, and the Dancing on Ice duo come face to face with the damaging effects of climate change.
Dancing on Thin Ice with Torvill and Dean airs at 8:15 p.m. on Christmas Day on ITV1.
