A homestead in serious danger of a raging California wildfire prompts Marty to clear cut surrounding trees and create an evacuation ark for the Grants' livestock while Matt devises a unique layer of fire protection to save the home from destruction.

Marty takes on a risky first-time build - a huge diverter trench to deflect the torrents of storm water devastating the homestead of musician Lou and his wife Stacey. But with a huge storm forecast, no one can predict if this rescue will succeed.

Shocked to find a bear den near the Counter family's Colorado homestead, the Raneys build an old school root cellar and innovative greenhouse and attempt to inspire two off-grid reluctant teenage sisters to help bring their father's dream to life.

A day in, Marty is hit with a bombshell the old well he's come to fix has already claimed its first victim. To set the Dagues on a path to self-sufficiency, the Raneys try to deliver a long-term water source, protein supply, and sustainable power.
