Fred was secretly loved by Mary Campbell, but lost his heart to the shepherd's pretty daughter to whom he presented his dog Ruby.
Through Bill's actions, Fred was sent away from home because of his alleged unfaithfulness to Mary Cameron, but was brought back when the latter declared that he had never made love to her.
Young Cameron was killed by Doyle on the journey and the latter left Fred's riding whip under the body so that the crime might be fixed upon him.
Fred, in due course was arrested and tried, but at this critical moment a sundowner who has witnessed the murder turned up and gave evidence, at the same time producing a handkerchief bearing the name of Doyle.
The sundowner, though offered a home with the happy young couple, could not remains in conventional quarters so responded again to the call of the bush.
