Barstow, a crook, conceives the idea of buying old automobiles, staging "accidents" with them, and settling with the railroad. At the Lone Point crossing one of his machines is hit by the train and the flagman is discharged because it appears that he has been negligent. Helen, the telegraph operatic, gets a day off and starts for the hills on horseback. She meets Duncan, a railroad detective sent to investigate the increasing number of crossing accidents.
