Daddy's Home 2 is about a split family that is trying to spend a Christmas together for the first time. The biological father, Dusty Mayron and the stepfather, Brad Whitaker, have a good co parenting relationship over Dusty and (Brad's wife) Sara's 3 children. As soon as their fathers Kurt Mayron and Mr. Whitaker arrive to join in the celebrations with their grandchildren, things get a little chaotic between the 2 sides of the family.
