The rollicking, merry, and heartfelt musical is all about a boy who is unique because everything he touches turns to ice. Jack Frost appears out of a snow bank and meets four humorous animals: a rabbit, a polar bear, a penguin, and a raccoon. He then escapes from the North Pole and finds himself in a "mistaken identity" situation.
Realizing he is different, they take him to Christmastown where he meets Elizabeth, a girl who befriends him, as well as the eccentric theatre director Mr. Holly, who thinks Jack is in town to perform in the holiday show! Hijinks ensue, temperatures soar, and the holiday is in jeopardy until friendship saves the day.
