David Langford, a member of the firm of Keegles and Langford, hardware merchants, has a violent quarrel with his partner, and kills him. Ned, Mr. Keegles' son, who has been expelled from college, returns on the night of the murder, and is suspected of the crime. He leaves for the west, where he becomes known as "Dakota." "Texas" Blanca, a Mexican, and John Duncan blacken the name of "Dakota" by unjustly accusing him of cattle stealing. Later, "Dakota" aids a young girl named Sheila during a thunderstorm, and he subsequently learns that she is the daughter of Langford, the murderer of his father. In revenge he forces her to marry him, and then she leaves for the Double R ranch, which her father has purchased. "Dakota" becomes implicated in a number of other diabolical plots, but emerges triumphant, and the climax of the drama shows him and Sheila living happily as man and wife.
