Brad Taggart (Will Ferrell) is a kindhearted radio executive 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, Taggart finds himself in a no-holds-barred battle to one-up his rival and win the approval of his family.
