Ferrell plays Brennan Huff, a sporadically employed thirty-nine-year-old who lives with his mother, Nancy (Mary Steenburgen). Reilly plays Dale Doback, a terminally unemployed forty-year-old who lives with his father, Robert (Richard Jenkins). When Robert and Nancy get married and move in together, Brennan and Dale are forced to live with each other as stepbrothers. As their narcissism and downright aggressive laziness threaten to tear the family apart, these two middle-aged, immature, overgrown boys will orchestrate an insane, elaborate plan to bring their parents back together. To pull it off, they must form an unlikely bond that will finally get them out of the house.
