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, viewers 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.

This captivating experience has been caught on NATURE: Arctic Wolf Pack (PBS Distribution). This documentary is narrated by Campbell Scott.
