"This holiday-themed children's film offers a unique take on the legend of Santa Claus and his tiny reindeer. In this movie, a young boy finds a deer in the forest he is sure is Santa's beloved Prancer. Determined to return the creature to the North Pole and his rightful destiny, the child overcomes the cynicism of his family to teach them and us a lesson about the true spirit of Christmas."

I don't think this one was as good as the original Prancer movie, but it was a pretty decent movie, and I did enjoy it, and would watch it again.
