Marie never expected to wake up in North Pole City, let alone become Santa's Emergency Replacement. It was a job she never wanted but couldn't turn down, thanks to Clarence, Santa's right hand man. Now, Marie has to work with Clarence, who believes she is some kind of criminal who will cause the destruction of everything he holds dear.
Trying to prove that he's wrong, Marie keeps making mistakes that push them even further apart. It doesn't help that she has a past she'd rather keep hidden.
However, trying to keep her past where it should belong isn't easy. Just when Marie starts to feel like things are coming together, a madman with a bone to pick, and Christmas to ruin, threatens the whole of the North Pole Organization. Marie must rely on Clarence and her new friends to help her face her past before Christmas is gone forever. But does she have the courage to truly be herself when it could mean losing everything?
