Summer is here, and for the Robertsons that means more pranks, parties, and, for Korie, planning for John Luke's big wedding. While the guys are busy bowling, golfing, and goofing, Korie finds shopping for engagement presents not so easy with Si and Kay along for the ride. As Jase and the gang attempt to work as a NASCAR pit crew, Korie and Willie take to the courts challenging John Luke and his fiancee, Mary Kate, to a doubles tennis match.
