Robert Fisher Clarke, a dreamer and engineering genius, on his way to Chicago, astonishes the Pullman porter by leaving the train at a small way station on the Sault Ste. Marie rapids. Clarke has seen a wonderful vision of a model industrial town situated on the banks of the river, utilizing the harnessed power of the great rapids. After he has succeeded in gaining backing for his project, a conflict between certain financiers so hampers the completion of his plans that he decides to bid farewell to the rapids. Before going, he proposes marriage to Elsie Worden, but when Jim Belding, a young engineer in his employ, meets with an accident in the river, Elsie suddenly awakens to the fact that it is Jim she loves and not Clarke. Clarke accepts his fate and takes with him little Sue, a child he has rescued from the rapids.
