Yellowstone's fierce winter forces wildlife into a struggle for survival against heavy snows, polar temperatures, and ferocious predators. No place on Earth is like Yellowstone in winter. This world of fire and ice has thousands of boiling hot springs, geysers, and bubbling mud pots. In Yellowstone, every animal struggles to find food and stay alive against an onslaught of heavy snows, polar temperatures, and ferocious predators. Beavers and grizzly bears retreat under cover from the endless blizzard, while the wolves, red fox, and river otters face winter head on.

A wolf lives to hunt. Red meat is their lifeblood, and the alpha must provide. But this is not a story about an alpha male: it's an epic biopic about one female wolf. We trace her against-the-odds rise to a position of extraordinary power for a female: leader of her pack. The She-Wolf became one of the most famous wolves to have ever roamed Yellowstone. And she overcame incredible challenges to create one of the park's most legendary wolf packs. Tragically, she was cut down by a hunter's bullet. But she left behind a thriving family and an enduring legacy.
