Robert Kraft (Boone) is the newly appointed chairman of a committee that oversees a large cemetery. The cemetery caretaker, Andy MacKee (Bikel), keeps a map in the cemetery office displaying the grounds and each gravesite. Filled graves are marked by black pins and unoccupied but sold graves are marked with white pins. New to the position and unobservant, Kraft accidentally places a pair of black pins where they don't belong, only to discover later that the young couple who had bought the grave sites in question died in an automobile accident soon afterwards. He believes that he marked them for death.
