"Trouble twins" Dallas and Florida have been shuffled between foster families and the orphanage all their lives. All they want is a loving place to call home, but they are mistrustful that one exists for the likes of them. Tiller and Sairy are a sweet couple who are each restless for one more big adventure while their bodies are still spry enough to paddle a canoe or climb a mountain. Their own children have grown up and moved away, so they're each looking for someone to help them and keep them company on their last exciting journey. And Ruby Holler is the beautiful, mysterious place that changes all of their lives forever. When Tiller and Sairy invite Dallas and Florida to stay with them and keep them company on their adventures, the magic of the Holler takes over, and the two kids begin to think that maybe, just maybe, the old folks aren't that bad.
