In the rugged Tennessee mountains, the Raneys scramble to save a family without suitable food, water and shelter. Marty constructs a massive yurt, Misty transforms a rundown pond into a food source and Matt creates a workshop with a propane forge.

The Raneys find an Idaho family struggling to survive in a geodesic dome home on the edge of a cliff. While Marty brings them water and Misty builds an innovative garden greenhouse, Matt and a local tracker corner a dangerous predator in a tree.
