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 Kimberley mining region. He offers to show Sparrow where the body is but there's a catch: Sparrow must travel 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 Western Australia pursued by outback police and adrenaline-soaked miners Sparrow begins 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?
