Pam and Mark Walker are celebrating their 25th wedding anniversary with a week-long family reunion and a ceremony renewing their vows. Mark breezily dismisses Pam's misgiving about temporarily closing Montis Inn and heads off to the county fair, to try his hand at both chainsaw sculpting and sheep shearing, with chaotic--and hilarious--results. Meanwhile, Pam juggles her thrill-seeking mother, who has a new "friend with benefits," and her non-conformist niece, who posts family secrets in her online blog . Then Mark's brother-in-law starts broadcasting his radio talk show live from Montis Inn. His remarks disparaging small-town life cause immediate rifts, especially when he sides with a real estate developer who wants to turn Lumby into a Las Vegas version of Aspen. As the controversy pits family against family, and neighbor against neighbor, will the spirit that defines Lumby triumph once again?
