A global journey reveals how animal mothers struggle to raise their young in an increasingly dangerous environment. In the Arctic, a polar bear and her two newborn cubs must find food across the quickly melting ice. In Africa, an elephant and her calf begin an arduous journey in search of water, but a pride of lions guards the pool. A humpback whale must keep her calf safe over thousands of miles as they migrate from the equator to Antarctica.
At the end of each Antarctic summer, the emperor penguins of the South Pole journey to their traditional breeding grounds in a fascinating mating ritual that is captured in this documentary by intrepid filmmaker Luc Jacquet. The journey across frozen tundra proves to be the simplest part of the ritual, as after the egg is hatched, the female must delicately transfer it to the male and make her way back to the distant sea to nourish herself and bring back food to her newborn chick.
