When a killer vanishes into the high-country wilderness, Segeant Andie Whitford must navigate challenging terrain and hostile locals with the help of Sam Dyson, the retiring sergeant she is replacing.
Andie's wife, Helen, and daughter, Kirra, forge new friendships among the locals, while Andie brings Damien, a local psychic and suspect, in as a consultant on the investigation of two missing people.
After Rose's distressing encounter in the bush, Andie suspects Ghillie Jack, an ex-army recluse, and investigates him in connection to the disappearances.
On the anniversary of a local boy's murder, Sam Dyson pledges to bring his prime suspect, Damien, to justice; Andie warns against harassment, but Sam can't help himself, forcing Andie to take action.
While searching for evidence in the wilderness, Andie spends the night alone, assailed by a flash storm and monstrous growling from the surrounding bush; rescue is at hand but from a very unexpected party.
The discovery of a drug crop leads Andie to suspect the missing couple were murdered after stumbling upon it; closer to home, Andie's wife gets high, and her daughter goes joyriding with her boyfriend.
Andie visits her elderly mother who makes a shocking confession linking Andie to the criminal conspiracy she has been investigating.
