A Minnesota man, determined to spend a Christmas in a milder climate with no snow, books a two week stay at the Southern Lights Mistletoe Lodge in southwest Louisiana. Mack develops an immediate camaraderie with his across-the-hall neighbor, Natalie, a widow of one year, there to escape the over-protective smothering of well-meaning family members. When a rare and far-reaching Arctic blast covers the south with a foot of bone-chilling, wet snow, Mack and Natalie experience the reality of winter in a southern town. Can the two new friends keep each other warm and toasty through the inconveniences of closed roadways, frozen pipes, and frigid temps?
