Brad Whitaker (Will Ferrell) is a kindhearted man who wants to be the best possible stepfather to his wife's (Linda Cardellini) two children. When her freewheeling ex-husband, Dusty (Mark Wahlberg), breezes back into town, Brad's feeling of insecurity quickly develops into an inferiority complex. As Dusty demonstrates his flair for athletics, home repair and bad-boy charisma, Whitaker finds himself in a no-holds-barred battle to one-up his rival and win the approval of his family.

The question remains, however. Can the modern urbanites survive the Great Outdoors and save what's left of the holiday?
