Kenai, a man who resents bears after a fight with one kills his older brother, is turned into a bear so he can see life from a different perspective. He is visited by the spirit of his older brother, and is told that, if he wishes to be changed back into a human, he must travel to the place where the lights touch the Earth, in other words, the Northern Lights. Fueled by hope, Kenai sets off on his long journey, and, along the way, encounters a younger bear, Koda, who is a chatterbox and a fun-loving spirit; Koda is trying to find his way back to his home, the Salmon Run, which, coincidentally, is right next to where the lights touch the Earth.
