Filmmakers Alastair Fothergill and Keith Scholey chronicle a year in the lives of an Alaskan brown bear named Sky and her cubs, Scout and Amber. Their saga begins as the bears emerge from hibernation at the end of winter. As time passes, the bear family must work together to find food and stay safe from other predators, especially other bears. Although their world is exciting, it is also risky, and the cubs' survival hinges on family togetherness.

An orphan bear cub hooks up with an adult male as they try to dodge human hunters.

Set in the wilderness of the Kamchatka Peninsula, the land of legends and the kingdom of wild brown bears, we follow the daily adventures of five wild brown bears.
