Kim’s widowed dad, John, is a grinch, and she’s decided enough is enough. She hatches a plan to break him out of his rut this Christmas and invites several unwanted guests, including John’s first love, Leslie, who he hasn’t seen in 30 years, her elderly mother, and her 10-year-old niece, who seem to want to give him nothing but grief.

Add Kim’s husband, Dennis, who John has never accepted, and her friends, Laney and Julie, a couple of over-the-top Christmas fanatics, and you’ve got a “Christmas to end all Christmases!” When they all get iced in together, seasonal madness ensues, and it’s a Christmas John will never forget.
