Bernard Harris and Donald Vickers are thrown together, stranded in an airport during a snowstorm, exchanging life stories to pass the time. Later, fearing for his sanity, Bernard tells his doctor about a strange experience he has had, an experience which links him to Donald in a way he cannot explain. Donald has taken care of his crippled and bed-ridden daughter, Gabrielle, since the death of his wife over ten years earlier. Gabrielle plays matchmaker with her father and an acquaintance, but does not live to see the results of her efforts. Bernard knows he has never met the girl, but is convinced their lives are linked in mysterious ways, convinced that she has saved his life.
