Two characters alone on a train. Well, alone in each other's presence in a railway carriage traveling from Paris to Frankfurt. One is a woman who wants to read a book, The Unexpected Man, by Paul Parsky. The other is Parsky himself, but his presence prohibits the woman from taking the book out of her bag. He, on the other hand, wonders what kind of a woman would sit on the train and not be reading a book. Will they speak to each other before the journey's end? And if so, what will they say?
