*Shots fired on Bitter Wash Road..' Hirsch is a whistle-blower. Formerly a promising metropolitan officer, now hated and despised. Exiled to a one-cop station in South Australia's wheatbelt.

Threats. Pistol cartridge in the mailbox.

So when he heads up Bitter Wash Road to investigate gunfire and finds himself cut off without backup, there are two possibilities. Either he's found the fugitive killers thought to be in the area. Or his "backup' is about to put a bullet in him.

He's wrong on both counts. But the events that unfold turn out to be a hell of a lot more sinister.
