Despite all differences of opinion: meanwhile, the bourgeois Brad (Will Ferell) and the reckless Dusty (Mark Wahlberg) have come together. Brad, the new husband of Dusty’s ex-wife Sara (Linda Cardellini), shares the educational responsibilities for the two children with Dusty. Together they make a really good patchwork family. But the trusty facade threatens to crumble, as the daddies each receive a visit from their daddys.
Just in time for the Christmas holidays, the grandfathers are snowing into the house. And they’re even bigger guys than their sons. This is how Mr. Mayron (Mel Gibson), the father of Dusty, turns out to be a real macho who does not mince his words. His counterpart Mr. Whitaker (John Lithgow), on the other hand, is even softer, more emotional, and stuffier than his son Brad. The apple does not fall far from the stem. To top it off, Dusty also has to deal with Roger (John Cena), the intimidating father of his stepdaughter Adrianna.
