Seven years have passed since Kinsley and Grace Harper-Scott became parents. They are looking forward to another Christmas with their family, but a Christmas wish that might not come true threatens to ruin the magic of Christmas. Desperate to make sure her kids don't stop believing in Santa, Kinsley will stop at nothing to get a dog for her daughter. Unfortunately, long road trips with way too many bathroom breaks, freak snow storms, meddling mothers, and a daughter that is way too similar to her all threaten to stand in the way.
