Calvin Carter, a prosperous business executive, possesses everything but overlooks those dearest to him. On the eve of Christmas, everything changes when the sign on his office building collapses on him. He regains consciousness in a hospital bed, cared for by Angie, a nurse who promptly informs him that he has 12 days (12 opportunities) to mend his ways and experience the "ideal" Christmas Eve. Failure to do so will result in severe repercussions.
