In the Norwegian lands south of Trondheim, not far from the Swedish border, temperatures can drop to -50°C in winter. Yet this harsh climate lends the landscape a special beauty. Ella Kjosnes, 16, is a sled dog leader. She prepares her six huskies for the 200-kilometer Femund race. While the lakes and rivers freeze over, Jan Moen goes ice fishing in the mysterious Hessdalen valley. If he doesn't catch anything, he may be able to observe the strange and partly unexplained light phenomena that regularly appear in the valley's skies. Not far away, Tone and Rolf Eriksen run a hotel on a lake that is only accessible by plane in winter.
