An inferno engulfs Marty and Mollee's cabin at the onset of winter and the Raneys must rally like never before to complete the unfinished clifftop cabin on The Upper 20 in record time complete with heat, water and power.

Marty attempts a treacherous trip across a frozen river, in an effort to bring heat to the new cabin. Misty and Maciah build a pump house to secure the family's new water source on the Upper 20.

The frozen access road to the Upper 20 becomes impassable, so Marty devises a risky way to transport massive equipment up the 300-foot icy cliff. Matt delivers a surprise to lift the family's spirits.
