In the far north of Canada lies one of the most inhospitable regions on earth: Ellesmere Island. Barely 800 kilometers from the North Pole, the island is home to polar wolves. In the second part of the documentary, the short Arctic summer has begun. Snow White's pups have grown properly in the meantime and can finally leave their den. Snow White also has a lone she-wolf to thank for this: Blackspot. She cares for the strange pups with similar affection and even suckles them - a behavior that has never been documented before and even amazes scientists.
