Three new build teams arrive to their build sites and begin work on their unique cabins in the remote Alaskan wilderness. Josh Tousignant and his crew make the long trip to Cordova to begin building the foundation for their clients' two-story cabin. John Donkersloot and Heather Rough oversee delivery of two 40-foot shipping containers for their cabin's foundation on a mountain build site in Seward. Finally, float plane pilot Chris Maynard and his crew fly out build materials and install helical piers for his cabin's foundation on Trinity Lake.
At Trinity Lake, Chris and Joe battle an 80-foot spruce that begins to fall too soon before a helicopter delivery almost goes wrong. Next, John and Heather fall behind while building the floor of their cabin due to the rain and need help getting back on schedule on Mt. Ascension. Later, Josh and his team must forklift their materials up the muddy driveway to the build site in Cordova after the semi gets stuck at the bottom. Finally, a complex build plan with too many parts and pieces threatens to shut the site down in order to get organized.
Josh and his team begin work on the interior walls and install the second-story floor joists in their Cordova cabin. At Trinity Lake, Chris must adapt when he runs out of lumber to build a dock and the framers he hired don't show up. Finally, wrong cuts and measurements threaten to put John and Heather further behind than ever on their Mt. Ascension build.
Chris Maynard and team prepare for two intense helicopter deliveries of roof rafters, and Greg precariously scales a raised rake wall to nail it into place. John and Heather are finishing the roof by installing insulation and metal sheeting when the forklift won't shift gears and threatens to knock over their timber frame. Josh and his team work from jagged pallets and rickety ladders late into the night to finish the three gable walls for Keith and Kathleen's cabin.
All three builds are running behind schedule and must rush to get ahead. John and Heather build a water catchment system but discover they aren't getting enough water pressure, Chris Maynard's windows are delivered by helicopter in a dilapidated crate that swings violently in the wind, and Josh comes dangerously close to tipping over his forklift and knocking over a gable wall.
John Donkersloot and Heather Rough's build is put on pause as they try to figure out how to install their drywall without covering their timber frame. A new team member comes to their rescue to help them finish framing their walls, and they get a late delivery of lumber to finally finish the decking system. Chris Maynard's windows spin violently in the air during delivery, Joe and Duane install the metal roofing tin on a steep slope, and the team works on finishing the insulation and tongue and groove walls before Chris runs out of time and money. Between the rain flooding the inside of the cabin and bears eating their supplies on-site, Josh Tousignant and his team also have to contend with breaking tools and winter looming, so Josh hires additional crew to help him finish the roof system, dormers and deck.
