A small town in outback Australia wakes to a crime of medieval savagery. A local schoolteacher is found taped to a tree and stoned to death. Suspicion instantly falls on the refugees at the new detention centre on Cobb's northern outskirts. Tensions are high, between whites and the local indigenous community, between immigrants and the townies. Still mourning the recent death of his father, Detective Sergeant George Manolis returns to his childhood hometown to investigate.
