A young boy and his mother spend Christmas 1943 with relatives in northern Minnesota while his father is fighting in the war in Europe.  They take a long journey by train to a snowy land of vast frozen lakes, deep and sparkling cold, and the most magical Christmas tree the boy has ever seen.  He knows this will be the last Christmas he will spend with his cousin, who is dying.  The boy's uncle overhears the two cousins say there is no Santa Claus, and in a grand gesture that is nothing short of a Christmas miracle, he restores the children's faith in the spirit of the season.
