David Morales, an Arizona high school principal and single dad, has lost the holiday spirit after also losing his wife a few years ago during the Christmas season. Now, David will do anything to avoid Christmas so he moonlights as a delivery driver during the holidays. But this year David's 14-year-old daughter, Noel, and his live-in sister, Marissa, are determined to bring the yuletide spirit back to the family and, with a little luck, also help David find love again via online dating. So when Sophie, a witty musician and customer on David's delivery route, swipes right on him, something magical happens between them.
