Wolves: A Legend Returns to Yellowstone

From lupine director David Douglas and nature specialists National Geographic, this documentary looks into the reintegration of wolves within the parameters of the oldest national park in the United States, Yellowstone of Wyoming. Self-described as the epicenter of everything that's still wild and untamed in America, this is the setting and eventual homeland of these transplanted tundra dogs. Struggling against declining numbers and an eroding environment, biologists have taken preventative measures to ensure the world does not lose another species to the endangered list or to the growing list of extinct creatures.
