Documentary about the world's first National Park, filmed over a two-year period. Ch1. Fire and Ice Yellowstone's residents try to survive the harshest of winters as temperatures plummet way below zero. Hibernation and migration offer an escape for some but, for others, paradise becomes a winter nightmare. Ch2. Return of the Predators Looks at the battle to stay on top of the food chain. Wolves, grizzlies and mountain lions play a critical role in keeping Yellowstone in balance and must do what it takes to survive. Ch3. Life on the Wing The park faces the dramatic consequences of famine, fire, floods and a big freeze. Ch4. Down the River Wild The Yellowstone River travels a 700-mile journey through a spectacular landscape, revealing trumpeter swans, daring river otters, and grizzlies and bison fording treacherous rapids.
At the very northern edge of North America is Ellesmere Island, where the unforgiving Arctic winds tear through the tundra, dipping temperatures to 40 below zero. Running through this shifting sea of snow and ice is one of the most hardened predators on the planet, the White Wolf. But as the spring melt approaches, these roaming hunters must adapt to being tethered parents as new additions to the pack have just been born. With their herds of prey continuing to move, we witness a desperate race to keep up and bring back a kill to the hungry mothers and cubs. Traveling farther and farther away from their den each day puts these hunters and their children at risk in this fight for survival.

The Miller-Urey experiment was the first attempt to scientifically explore ideas about the origin of life. Stanley Miller simulated conditions thought be common on the ancient Earth. The purpose was to test the idea that the complex molecules of life (in this case, amino acids) could have arisen on our young planet through simple, natural chemical reactions.
