When a neglectful, public official father ignores his daughter's mental illness, blaming it on weak moral character, she is left in a world all her own. A world that is 365 days of Christmas. Her constant one night stands results in a pregnancy, and Sandra believes she is Mrs. Claus and her child, if it's a boy, will be the next Santa Claus, carrying on the long line of Santas before him. The child arrives, and it is indeed a son. Chris Cringle grows up believing the delusional world of his mother. Never being allowed to leave the house, he knows nothing else. Even her caretaker doesn't have the heart to tell the boy he won't be Santa someday, and does nothing to dissuade these teachings. As Chris grows up, he believes that the men his mother brings home and dresses up like Santa, are indeed Santa Claus, his father. But the beatings these men give him, to teach him the lessons Sandra wants him to learn, will alter his life forever. When Sandra kills herself, Chris takes his supposed rightful role of Santa Claus, and goes out into the world to teach people their lessons. With no concept of death, he takes the lessons too far. Are you naughty or nice? You better pray that you're nice when this Santa comes sliding down your chimney, or else, you might learn a lesson or two, and end up dead. Merry Christmas! That is, if you're still alive to enjoy it!
