Miss Ellie gives a home to lost dogs, and her latest guest is Josh, a puppy who desperately wants to be a hero, a Saint Bernard. He gets his chance when Santa Claus and his reindeer get trapped by a snowstorm and must be rescued. Josh becomes the most famous dog in the community, adored by his fellow-mutts, Miss Ellie and another neighbor, whose own set of huskies helps him deliver the mail by sled. It’s a family-friendly tale worthy of the holiday season.
