Helen, a "diamond runner," reaches South Africa.

Whispering Smith is a virile, fearless type of the true American whoso theory of life is to give every man a chance to show what is in him. There is nothing of the bully or braggart about him. He is only a man who knows instinctively what is right and never falters in his steps to see that justice is given where it is deserved and crime punished on the same basis. Originally shot as a serial to be called "Whispering Smith", distributor Mutual Films decided to release it as two separate films - this film, which was released first, and Medicine Bend (1916).

Dan Oakley becomes a railroad manager and his attempt to slash expenses by layoffs and lengthening hours incurs the workers' wrath. With the help of Griffith Ryder, labor leader and newspaper editor, they call a strike. The water main which supplies the railroad yards is cut, and a hot engine starts a fire. With water unavailable, the fire spreads to town, but through his superhuman efforts, Oakley gets it under control. His heroic moves win favor with the workers, and the strike is history.

Two rival mountain clans that have been feuding for years begin a new battle over the moonshine whiskey trade. A young man and a girl from each of the different clans try to end the feud, and wind up falling for each other.

Whispering Smith, a railroad detective, is sent to Medicine Bend to suppress the looting of cars.
