Santa has a busy task every Christmas Eve, going around the world visiting children and leaving them special gifts. He usually visits the houses that are festively decorated, as he knows the spirit of Christmas dwells within these houses. This year, he makes a detour to visit a house that doesn't show any sign of festive celebration. By the fireplace, there is a table with milk, cookies, and a card for Santa. Santa finds a stack of Christmas cards dating back many years, cards that were meant for him but never claimed. This is the year that Santa learns something new about the true spirit of Christmas, the one that is found deep within a person who cares for the world around them and the people they care about.
