The mother Polar Bear is admired for her beauty, ferocity and patience. In a frigid landscape, a Polar Bear emerges from her maternity den with cubs. The Innuit people call this largest predator on earth "Nanook" and bestow upon it spiritual power. Most admired by the native people is the mother Bear which, over the course of two or three years, will fearlessly protect and patiently teach her cubs how to survive in their beautiful, high Arctic home.
