The Hecks count down the 12 days of Christmas with Frankie's parents, Pat and Tag, when they come to town to spend the holiday with the family - much to Mike's dismay. But when Frankie decides that she wants to take the focus off of the gifts and make it a simple Christmas, Pat and Tag have other ideas.

Mike freezes Frankie out because he can't fathom how she inadvertently paid $200 for a small bottle of eye cream that she thought was priced at $20. Meanwhile, Axl's fathering techniques are put to the test when he has to take care of a mechanical infant doll for health class, and Sue and Brick desperately search for a way to fix a hole that they caused in Sue's bedroom wall.
