With her fiancé far away fighting a war in Korea, Sarah faces a blue Christmas in Johnstown, Pennsylvania in 1953. But going to work as an elf at Glosser's Department Store turns her holiday upside-down. Santa Claus, played by fellow employee Frank, falls beard over sleighbells for her. When the magic of the season at Glosser's lights a spark of romance between them, Sarah is torn between the man at war and the one in the St. Nick outfit. On the night before Christmas, she must make a fateful choice that changes everything...and leads her to a crossroads 63 years later at the famous musical Christmas tree in Johnstown's Central Park.
