Two brothers meet at the remote fence line separating their cattle farms under the relenting sun of the remote outback. In an isolated part of Western Australia, they are each other's nearest neighbour, their homes three hours' drive apart. They are at the stockman's grave, a landmark so old that no one can remember who is buried there. But today, the scant shadow it casts was the last hope for their middle brother, Cameron, who lies dead at their feet. Something had been on Cam's mind. Did he choose to walk to his death? Because if he didn't, the isolation of the outback leaves few suspects.
