A BAD MOMS CHRISTMAS follows our three under-appreciated and over-burdened moms (Amy, Kiki, and Carla) as they rebel against the challenges and expectations of Christmas in hopes of creating a more perfect holiday for their families. And if that was hard enough, they have to do all of that while hosting and entertaining their ultimate holiday foes: their own mothers. By the end of the journey, our moms have redefined how to make the holidays special for their families and it ends up bringing them closer to their own moms.
