Nan is a contented girl living with her father and her brother, Lige. Dr. Brenton finds diversion in teaching Nan geography, and is secretly in love with her. Nan meets Gilbert, the dissolute son of their neighbors, while he is out riding in his auto, and innocent of his intentions, she accepts his invitation to go out riding with him. During one of their clandestine meetings they are discovered by Lige, who unjustly suspects Gilbert of having wronged her and he forces a promise from Gilbert to marry her. Gilbert then tries to escape north, and while he is speeding away on the train, Lige discovers his escape. He pursues him in an auto, catches up with the train at the next station and forces Gilbert to return and wed Nan. Accompanied by her brother and her father, Nan and Gilbert are wed by a justice of the peace. From there they go to Gilbert's home and when Gilbert's parents hear the story from their son, how he was forced into marrying Nan, they order Nan and all her people out of the house and promises that they will have the marriage annulled. Gilbert is stricken with a fever and confesses to Dr. Brenton, who is called upon to attend him, that Nan has not been wronged. Gilbert dies exonerating Nan and after the passing of years Nan marries Dr. Brenton.
