Maren Vedvik Dammen and Frida Brockmann are students at what is probably the only outdoor adult education school in Alta, Norway. They were surprised by a blizzard during a survival course and had to dig a cave in the snow to survive the night. When the moon is shining, however, a polar night can be so light you can still read a newspaper. And if you’re lucky, you’ll see the Aurora Borealis, the Northern Lights shimmering across the sky. This documentary looks at mushers who drive their dog sleds in one of the world’s toughest races, at women rally drivers who are just as tough as their male competitors, and ice divers, who find magnificent king crabs when they explore submerged wrecks. The male-voice choir Mieskuoro Huutajat, or "shouting men," which was formed during a particularly hard winter three decades ago, has now become an international hit.
