Mary, the three-year-old daughter of John Denby, a railroad president, is kidnapped, and all trace of her is lost. Fourteen years elapse. There has been a terrible wreck on Denby's road and Graham, the engineer, is made the scapegoat. In spite of the fact that he merely obeyed orders, he is sent of to prison. Mary is returned to Denby, the kidnapper explaining that he stole her when his own little daughter was killed, but that now he feels he must return her to her parents.
