A look at the life, passions, achievements and tragedies surrounding the famous Jacques Cousteau, featuring an archive of his newly restored footage. Its focus will be on the inventor-explorer-environmentalist-filmmaker revolution, i.e., giving mankind the resources to explore the ocean with the Aqua Lung, calling attention to ocean pollution, and his long-time collaboration.

Grasslands cover one quarter of all land and support the vast gatherings of wildlife, but to survive here animals must endure the most hostile seasonal changes on the planet. From Asia's bizarre-looking Saiga antelope to the giant anteaters of Brazil, grassland animals have adapted in extraordinary ways to cope with these extremes. In the flooded Okavango, lions take on formidable buffalo in epic battles, on the savannah bee-eaters take advantage of elephants to help catch insects and, on the freezing northern tundra, caribou embark on great migrations shadowed by hungry Arctic wolves.

Experience the world from the viewpoint of animals themselves. From spellbinding wildlife spectacle to intimate encounters, Planet Earth II takes you closer than ever before.
Remote islands offer sanctuary for some of the planet's strangest and rarest creatures. The rare pygmy three-toed sloth enjoys a peaceful existence on an idyllic Caribbean island, while nesting albatross thrive in predator-free isolation. But island life always comes at a cost. On the Galapagos Islands, young marine iguana must escape an onslaught of deadly racer snakes the moment they hatch from the sand. On the sub-Antarctic island of Zavodovski, life gets more extreme still. Every day, one and a half million penguins risk being battered against the rocks by fierce waves as they try to get on and off the island.

In the boreal forests of Europe, a young brown bear clashes with wolves and tries to find a mate beneath the stars. On the edge of the Arctic Circle, lies an enchanted wilderness. In Europe's boreal forest, It's so far north that in winter, nights can last 20 hours. This woodland is home to a population of secretive bears that lives most of their lives in the dark. But now, using low-light cameras we can see their nighttime world as if it were day.

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.

The polar regions of our planet may seem beyond the reach of most of us, but they are not beyond our influence. We, unintentionally, are changing these frozen worlds, and these changes will not just affect the poles but the whole planet. On the unforgiving frontier of climate change, polar bears, walruses, seals and penguins find their icy Edens in peril.
