The astonishing story of an annual natural phenomenon on the north slope of the Arctic. Every year, up to eighty polar bears gather on the frozen shores of Barter Island, near the village of Kaktovik, to feast on the hunter-harvested bowhead whale remains. This extraordinary gathering not only highly unusual, it turns dangerous as the whale bones are picked bare, and the huge group of polar bears heads for the town.
