Stormborn

Summer has given way to autumn in the lands of the North. There's a crisp chill in the air, the days are shortening, and across Scotland, Norway, and Iceland, the animals race to feed their families, find a mate, or make a move before the darkness of winter arrives. From the testosterone-fueled battles of the grey seals to the baptism by fire of an abandoned Arctic fox to a perilous two-mile swim made by migrating reindeer, see how the "Stormborn" fight wild weather, diminishing food supplies, and each other to make it through another season.
