Snow leopards are one of the most elusive and mysterious animals on Earth. They're rarely seen and little is known about their social behavior, but in the Tibetan Plateau, a dense population exists in a valley shared by a limited number of prey and a whole lot of enemies. Enter this rarely seen world and witness the story of a mother's struggle to raise her two cubs while outwitting her rivals. Her devotion to her young ones is strong, but it will take all her strength and stamina to keep them-and herself-alive in this harsh habitat.
