It's Christmas Eve. Two toy worlds live together in a family living room. On one side is the Christmas tree, with Santa and his elves. On the other, the Nativity scene with the three wise men and the rest of its inhabitants. Just as everyone is ready to start celebrating Xmas they find out that Santa's sledge and all the presents has gone missing. Christmas is in danger, and our heroes Sam and Sarah must set off on a magical adventure in order to save the most magical time of the year.
