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.

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.
