National Geographic explorer and photographer Ronan Donovan arrives in the Arctic to begin his quest to find and document a pack of white wolves as the year’s pups are born. He journeys to a remote region in the mountains called Wolf Valley and there he finds a family of wolves—but these elusive creatures soon force him to reevaluate his mission.

National Geographic explorer and photographer Ronan Donovan has been in the Arctic for six weeks searching for a wolf pack that will allow him to tell the incredible story of their hidden world. After making the difficult decision to leave Wolf Valley, through perseverance and luck he meets a new pack of wolves: the Polygon Pack.

National Geographic explorer and photographer Ronan Donovan has finally gained the trust of the white wolves and is able to observe their lives up close. The family has not eaten for nearly a week and they’re hungry and restless. The pack’s matriarch leads her children on one last hunt and after leaves her family in turmoil.
