الموسم 1، الحلقة 4: Summer is the season of plenty for most animals, but not for polar bears. They can't hunt seals until the sea freezes over again. Stuck on land they grow hungrier by the day. For other animals, summer is when youngsters, born in the spring, must learn how to survive in Canada's vast and unforgiving wilderness.
