在这部老爸当家2喜剧片中,在续集中，亲爹沃尔伯格和继父法瑞尔决定把他们的分歧放在一边，携手为孩子们打造一个完美的圣诞节，这时候，孩子们的两个爷爷也到了（也就是两个爸爸的爸爸）。这一次，性格好强的爷爷吉布森遇到了极度敏感的爷爷利高特，一场大战也将掀起。
After finally becoming friends at the end of the first film, Brad Whittaker (Will Ferrell) and Dusty Mayron (Mark Wahlberg) have a co-dad system where their two children, Megan (Scarlett Estevez) and Dylan (Owen Vaccaro), take turns at each father's house. Dusty has also remarried, this time to Karen (Alessandra Ambrosio), a writer, and is stepdad to Adrianna (Didi Costine), Karen's daughter. Brad and his wife, Sara (Linda Cardellini), along with Dusty and Karen, attend a school play for Megan, where she announces to the whole audience that she doesn't like the fact that she has to go back and forth to different houses all the time. Back at the house, after the play, Brad and Dusty decide to do away with having two separate Christmases and instead do one "together Christmas". Dusty, however, finds out his tough fighter pilot/astronaut father Kurt (Mel Gibson) is coming for Christmas..
