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.

When the bears learn of the legendary Last Great Wilderness, a fabled bear paradise, they believe that this must be their ultimate destination.

"The four bears have reached the mountains where Toklo spent his cubhood--but they soon discover that the home Toklo has returned to is nothing like the one he remembered"--

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.

As the four bears head toward warmer territories, polar bears Kallik and Yakone wonder if they've made a mistake leaving their natural home, while Toklo, desperate to leave the struggles of their journey behind, thinks about leaving the group and starting a new life on his own.
