Nothing warms the heart like the story of a boy and his dog. Lonnie (Johnny Whitaker) and Text (George Spell) are two friends determined, against all odds, to turn a misfit hound into a hero. Tennessee farmer and dog trainer Harve McNeil (Earl Holliman) tells his son Lonnie that his dog, Moreover, is a good-for-nothing "biscuit eater."

Two little boys have faith in a dog they name Promise, so much faith that they enter him in the championship trials for bird dogs. The favorite is Georgia Boy bred and trained by the boys' fathers. And if Georgia Boy doesn't win, the fathers may both lose their jobs.
