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.

The Raneys return to Alaska to discover their own homestead in utter disrepair. Beetle kill has destroyed their only access, so they race to build a steel tram before the deep freeze sets in. But can it withstand the force of a 7.2 earthquake?
