One foggy morning on the banks of the Murray River, a body is found in a burnt-out area of grassland. The heavily tattooed victim, who has suffered two bullet wounds to the head, is identified as Freddie Jones, a bikie from Moama. Detective Sergeant Zoe Mayer is on the case, alongside her trusty service dog, Harry. Although Zoe is determined to track down the murderer, she finds herself stonewalled at every turn-by Freddie's family, his associates and even the local police. But then a second body is discovered, and soon all bets are off.
