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).

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