Hannah's husband Millie (aka Raymond "Millie" Millington) is struck by a car while riding his bicycle on a frontage road in rural Montana. The driver flees the scene, leaving Millie to die alone. As the investigation into the crime moves forward at a glacial pace, Hannah, a novelist, reshapes the narrative to suit her, and her audience's, needs. Eventually the driver is revealed with the help of a slightly psychic neighbor, which forces Hannah to work even harder at streamlining her truth.
