For many years, Laura Pickler has relished the prestige and admiration afforded her as the wife of Iowa's longtime butter-carving champion, Bob . When Bob is pressured to retire from competition so that someone else has a chance at victory, Laura decides to enter the contest herself. But, when three formidable opponents also enter the fray, Laura vows to win at any cost, including recruiting her stupid ex-boyfriend for a bit of sabotage.
