After a pandemic devastates the world's population, a man is driven only by the need to find food and stay out of the way of other survivors, many of whom have become violent. At the home of a family who were members of the Church of Jesus Christ of Latter-day Saints, he finds a map showing homes of Church members in the stake. He follows the map from house to house, taking refuge and beginning to learn about the Church through books he finds, including the Book of Mormon. Each day he is unsure how much longer he'll survive, but he realizes he is becoming converted to the religion he's been reading about.
