After Hurricane Helene obliterates a 100-year-old farmhouse in NC, a once self-sufficient family is left with nothing; the Raneys face their most urgent mission yet: to rebuild a fourth-generation homestead, making it 100% self-sustainable.

Two young couples in Alaska struggle with their homestead near the Arctic Circle; but with no access, no water and no shelter, survival is impossible; the Raneys must engineer all-season solutions for the harshest climate they've ever faced.

A Colorado family's dream of self-sufficiency is crumbling under the destructiveness of their bison herd. To supply the ranch with food and water, the Raneys must first tame the chaos and build a path to true self-sustainability -- starting with the herd.

Marty returns to Interior Alaska to help a single mother whose homestead is on the brink of ruin. With a quake-damaged water line and bears circling the property, he must act fast to protect the Adams family's animals and dream.
