Sean Astin, Jean Smart and Kathy Najimy lend their voices to this heartwarming animated adventure that picks up where the first two films in the series leave off. Balto (voiced by Maurice LaMarche) and his dogsledding friends are enjoying an idyllic life until a pilot lays down the gauntlet and claims he can deliver mail faster than they could ever attempt. But when he runs into trouble, the pooches must come to their critic's rescue.
