Pretty Nan Morgan is admired by all the boys in Lariat and likes them, every one, but her heart belongs to Broncho Billy, who proudly announces to the boys one day that he wants to introduce them "to the future Mrs. Broncho." Matters glide along smoothly until about the time Broncho is thinking of putting the ring on Nan's finger. Nan meets a young stranger from the east, who, after several meetings with her, persuades her to elope with him. Nan does so, leaving a note which Billy finds, saying she has gone with another and for him to forget her. Heartsick, Broncho leaves the ranch. At the railroad station he meets a pretty young woman who asks information concerning her husband. It is not until she shows Broncho a picture of him that he realizes that it is the scoundrel who has taken Nan from him. Assuring the little woman he will send her husband to her, Broncho rides wildly along the trail, heads off the fleeing scamp, and forces him to return to the station with Nan. There Broncho reunites the patient wife with her husband, whose perfidy she is ignorant of, and Nan, realizing what Broncho has saved her from, sobs out her repentance on his shoulder.
