With DS Manolis on leave in Greece, Senior Constable Sparrow receives a phone call from a man who wants to turn himself in.

Bob is sixty-five years old, confined to a Perth nursing home. But thirty years ago, he killed a man in the remote northern Kimberley mining region. He offers to show Sparrow where the body is, but there’s a catch: Sparrow must travel north with him under the guise of being his carer.

They are accompanied on the drive by another nursing home resident: Luke, thirty years old, paralysed in a motorbike accident. As they embark on their road trip through the guts of Western Australia, pursued by outback police and adrenaline-soaked miners, Sparrow beings to suspect that Bob’s desire to head north may have sinister motivations. Is Luke being held against his will? And what lies in store for them when they reach their goal?
