Half wolf Balto has a litter with his full husky wife. Most puppies resemble her and are easily adopted by the Wild West villagers. Only one daughter, which has his lupine traits, must be raised by them and devoted goose Boris. She also proves a free-spirited rebel, drawn to the wild. Balto spares no effort to protect his stubborn, near-adult pup, which leads to both of them confronting and joining wise old 'wolf shaman' Nava's troop, which needs to make hard choices, requiring a strapping younger leader.
