Heather, Andrew and Steven McCall ask the Gaines to help them find a retreat for their missionary parents. Dr. Tim McCall and his wife Janice run an orphanage in Uganda, living almost year-round in a 160-square-foot home. They're entrusting their kids and the Gaines to find them a comfortable refuge for their biannual visits to Waco. But their sanctuary may be out of reach, as unexpected structure problems challenge a modest budget and add stress to an already tight timeline. The drama continues as the Gaines run into a serious permit problem that could be a deal breaker for this fixer upper. Can the Gaines battle bureaucracy and complete the McCall's home in time for their short sabbatical?
