Three young bears of different species--one black, one polar, and one grizzly--travel on a perilous quest to the Northern Lights, escorting a shape-shifting grizzly cub whose destiny will affect them all.
Three bear cubs of different species are united for the first time as they begin their long journey in search of destiny, hope, and what it truly means to be a bear in the wild.
The four bears finally arrive at the legendary Last Great Wilderness, thinking it is the end of their long journey, but they discover that their true mission has really just begun.
Despite their misgivings about the many dangers that lie ahead, the bears venture out onto the Everlasting Ice and learn of their final destination with the help of a mystical bear spirit.
At the edge of the Endless Ice, the four bears Ujurak, Toklo, Lusa, and Kallik reach Star Island, where a large group of bears is in trouble but believes Lusa is destined to help bring back the favor of the spirits.
