Jessica is at the end of her tether. Her rotten husband has left her and her two small boys for some new floozy, the kids have been sick, and she barely has enough money for groceries, let alone the Christmas toy her boys have been asking for since last year: the Shelf Elf.
But what is she supposed to do when it's her first holiday season as a single mum? Makes sacrifices, of course, and Jessica is determined to make her children's Christmas as magical as she can.
Her efforts don't go unnoticed, however. Someone has been watching her, and reporting back to the Big Man, who decides it's time Jessica got a little gift for being such a good girl... a gift that involves getting a little naughty first.
