Noble dog Balto returns in this direct-to-video sequel to the popular animated adventure that bears his name. Balto (voice of Maurice LaMarche) has retired from his chores as a sled dog, and his son Kodi (voice of Sean Astin) has taken his place. But Kodi's livelihood may be in danger when mail airplanes come to the frozen North, which threaten to make the post office's dog teams obsolete. In order to determine who can deliver the mail faster, the pilot of the carrier plane challenges the leaders of the dog teams to a race; however, when the mail plane is involved in a serious accident, Balto and Kodi must put aside the rivalry to help save injured pilot Duke (voice of Keith Carradine). Balto III: Winds of Change also features the voice talents of Jean Smart, David Paymer and Kathy Najimy.
