[2] The plot is set in the region near Mount Kosciuszko during the early days of European settlement of New South Wales.

Neal Blackmore, a land speculator, discovers a gold deposit on the property owned by selector John Hillgrove and tries to get his hands on it.

The Blackmores henchman Solly Steele uses a loaded whip to kill an old fossicker called Kosciusko Joe, who also knows about the gold deposit, and frames Jack Hillgrove for the murder.

Comic relief is provided by Miss Cruikshank, Lily's man-hating maiden aunt; a magician called Charles Spinnifex (who falls for Hillgrove's daughter Cissie) and his assistant Willie Staggers; and a Scottish policeman.

[3] [4] During one scene, Spinnifex's magic abilities allow Jack to escape the villains; in another, they enable the heroes to play upon the superstitions of the Blackmore henchman, Barcoo.
