It's 1964, and Abraham Lincoln's daughter, Sarah, daydreams about meeting her father. Her mother, Joan, met Lincoln nine years earlier when he was transported to Evanston, Illinois, from his own time and place for a day. When Sarah's stepfather, Will, a Lincoln scholar, doesn't return home from an overnight trip, Sarah and her mother have no way of knowing that he has traveled back in time to 1833 in the same mysterious way Lincoln came forward. The two grow more and more nervous waiting for him to come home. A stranger's phone call and the discovery of an abandoned truck will push daughter, mother, and their old dog, Rusty, away from home in search of Will.
