Bonnie, a wholesome girl of the western mountain country, becomes engaged to Ralph Stuart, a cowboy, after he promises her that he will stop drinking. John Trent, an Easterner, spending his vacation in the little western town, falls over an embankment. Bonnie and Ralph see him fall and go to his assistance. Ralph notices that his sweetheart is very much concerned about the stranger's wounds, which infuriates him. With Bonnie's help, Trent manages to get back to the hotel. Jealousy drives Ralph to drink. He goes to Bonnie and upbraids her. She returns the ring and dismisses him. Almost insane from whiskey and jealousy, he attempts to kill Trent. Bonnie comes to Trent's assistance and he gets away on her horse. Ralph gives chase and brings Trent to earth in a very sensational manner. Bonnie, however, has followed the men and she pleads with Ralph to spare Trent, whom she has grown to love. Ralph, now sobered, grants her request, even though it is at the expense of his own happiness.
