Having achieved a tenuous co-parenting harmony, stepfather Brad and biological dad Dusty now face a new challenge: the holiday season. Their fragile peace is tested when they decide to forego their individual Christmas celebrations in favor of one combined family holiday. As the blend of Brad's earnest attempts at crafting the perfect Christmas clashes with Dusty's laid-back approach, the duo aims to ensure a harmonious holiday for their children. However, their plans take an unexpected turn with the arrival of their own fathers.

Brad's father is the affectionate and emotional Don, whose overwhelming love contrasts dramatically with Dusty's rough and tough father, Kurt. The grandfathers could not be more different, causing further complications in the already intricate family dynamics. As the fathers' presence amplifies tensions and old rivalries, Brad and Dusty must navigate the minefield of their competing parenting styles, while also contending with their fathers' strong personalities. This sets the stage for a showdown that puts the co-dads' co-parenting ability to the ultimate test.
