The Barnwood Builders float down the Ohio River and land in Paducah, Kentucky, where they try to save a little cabin in a big quarry. The cabin is in rough shape, but these guys don't give up on it. Their time in Paducah is filled with pioneer ingenuity. Alex Makes a chair, Johnny drives a dump truck, Sherman makes a quilt and Mark helps build a barnwood table.

Mark Bowe and the Barnwood Builders take the logs from the Bird's-Eye Barn across the New River and put them back together on a West Virginia island. They have to reconfigure the barn to turn it into a modern fishing cabin with a complicated design. While the crew finishes up, the boss goes to visit the completed Wildrock Pavilion from also from season 3.
