A brother and sister live on a farm in south-eastern New South Wales which possesses valuable timber.
The timber is felled by a nearby mill owner for the benefit of the brother and sister, although at the time it appears to be a devious act.
While the suspected villain rides on the Sydney Express (The Northbound Limited), he is chased by the brother and the mill owner's daughter.
Following the train chase, the misunderstanding is revealed when the mill owner presents a cheque for felled timber from the land.
The film included documentary scenes of Melbourne, Wangaratta, and the country town of Seymour are shown.
