In the desolate outback town of Finnigans Gap, police struggle to maintain law and order. Thieves pillage opal mines, religious fanatics recruit vulnerable youngsters and billionaires do as they please. Then an opal miner is found crucified and left to rot down his mine. Nothing about the miner's death is straightforward, not even who found the body. Homicide detective Ivan Lucic is sent to investigate, assisted by inexperienced young investigator Nell Buchanan. But Finnigans Gap has already ended one police career and damaged others, and soon both officers face damning allegations and internal investigations. Have Ivan and Nell been set up, and if so, by whom?
