Przewalkski s Horse is a modern hejira following the misadventures of Keith Fine, a disgruntled former postal employee. When Keith discovers his wife s infidelity, he leaves his job, his family and his home and hits the road. He hopes to find some remaining fragment of who he had once been. Cut off from everything familiar in his life, he sets off on a journey to reconnect with his earlier life as a young man in Chicago. He has been reading and has become upset by the columns of one Adrian in the Chicago Daily Mail, and decides to find the writer and give him a piece of his mind: a classic case of anger displacement, perhaps. On the way, he meets and gets entangled with a variety of odd characters who, like him, have taken to life on the fringe of society. Keith works toward building a new life with a new family, but eventually he realizes he is only mirroring his previous existence, and that he has been trying to escape, not life, but himself.
