The Raney family kicks off the most ambitious rescue ever, on their own 40 acres. As multiple generations gather to chip in, Marty attempts a dangerous river crossing to get thousands of pounds of gear to the homestead.

An aerial supply mission faces turbulent skies as Marty breaks ground on massive foundation posts for his cabin. Misty and Maciah begin an innovative greenhouse that requires lumber, but Matt and Katie must first troubleshoot the new sawmill.

With only two weeks left to finish their ambitious self-rescue, Marty races to complete the walls of the log cabin. Misty expands the garden and builds a goat shelter, while Matt takes the next generation on a hunt for gold.
