Kris Kringle, Father Christmas, Saint Nicholas, Santa Claus. He goes by many names and anyone on the street could tell you who he is. Everyone knows of him but who really knows him? No one better than his family of course.
Traditionally Santa Claus will choose his bride and they will have one child, a son, to carry on the line of Santas. When it comes time for the current Santa and his Mrs. Claus to have their child, imagine their surprise when they have twins! Mrs. Claus bears a son and a daughter, the first daughter of Santa Claus ever to be born.
Krissi is raised as a child of Santa, just as her brother Nick is. They go through their elf training just as all past Santas had and when it comes time for their first assignment as elves in training they're sent out together.
Alone and in rural United States these two twins enroll themselves in high school and must decide who in this town is naughty or nice because Santa can't do everything himself...
