In the mountains of Canada's Yukon, a litter of wolf pups is born. The first two males of the litter gain the attention of Mammak and Aurora, one of them is a male pup who loves to fight, upon which they bestow the name Tulok (an Inuit name meaning "warrior"). The other is named Kanak (meaning "the golden one"), the latter of whom becomes the most cherished in the litter. Over time, a rivalry develops between these two brothers. Tulok has emerged as a social awkward and slightly eccentric pup who avoids social situations, while Kanak has become the favorite among his littermates. Their skills are put to the test as their father trains them to hunt caribou.
