Disneynature's BEARS takes viewers on an educational and entertaining adventure through the Alaskan wilderness, where the documentary follows a fiercely protective mama bear named Sky and her two young cubs, Amber and Scout, over the course of an entire year. Narrated by John C. Reilly, the film trails this young family as they venture down a mountain in search of sustenance, and encounter a variety of threats, including a pair of imposing male bears named Magnus and Chinook, as well as a crafty -- and very hungry -- wolf named Tikani. As the seasons shift, Sky teaches Amber and Scout the secrets to recognizing danger and foraging for food. Later, as salmon appear in the local waters, Sky attempts to build her fat reserves for the coming winter. But it won't be easy, because challenges await over every summit, and the competition for food can be fierce.
