A Bad Moms Christmas
For our three main mom characters: Amy (Mila Kunis), Kiki (Kristen Bell) and Carla (Kathryn Hahn); matters come to head regarding her personal issues with their respective moms, when:
Nonetheless, all three women converge in the Church where Ruth was going for Midnight Mass and they talk their personal mother-daughter issues through. Meanwhile, Amy has a conversation with her father, Hank (Peter Gallagher), in which he clarifies that Ruth's ruthlessness and obsession with perfection was nothing but an attempt to mask her insecurities and fear of thinking that she might had raised Amy wrong. When Amy sees the light in this, she rushes to the church and has a tearful reconciliation with Ruth, after which they join forces to massively clean up the house, redecorate and attempt to have a nice Christmas Day. In turn, Sandy lets Kiki know that she will respect boundaries and move back to Bismarck; and Isis, having had a change of heart, returns to Carla to offer to be there for her and pay her debts back to her.
That night, the whole gang gathers at Amy's to have Chinese food -as Amy planned- for dinner. While there, Ty (Justin Hartley) shows up expressing his love for Carla, which she corresponds to; and gives a very steamy strip show to prove it. And then, the three moms of our moms -Ruth, Sandy and Isis- announce that they will be going to Vegas on a trip to see Wayne Newton "before he dies".
The movie ends with a montage of the main cast (including the Santa strippers and the mall Santa) doing a naughty dance to a Christmas tune while the main credits roll.
