One outback town. Two puzzling murders. Fifty suspects.

In Unamurra, a drought-scarred, one-pub town deep in the outback, two men are savagely murdered a month apart - their bodies elaborately arranged like angels.

With no witnesses, no obvious motives and no apparent connections between the killings, how can lone police officer Detective Dana Russo - flown in from hundreds of kilometres away - possibly solve such a baffling, brutal case?

Met with silence and suspicion from locals who live by their own set of rules, Dana must take over a stalled investigation with only a week to make progress.

But with a murderer hiding in plain sight, and the parched days rapidly passing, Dana is determined to uncover the shocking secrets of this forgotten town - a place where anyone could be a killer.
