Art dealer Alex Clayton travels to Victoria's Western District to value the McMillan family's collection. At their historic sheep station, she finds an important and previously unknown colonial painting - and a family fraught with tension. There are arguments about the future of the property and its place in an ancient and highly significant indigenous landscape.

When the family patriarch dies under mysterious circumstances and the painting is stolen, Alex decides to leave; then a toddler disappears and Alex's faithful dog Hogarth goes missing. With fears rising for the safety of both child and hound, Alex and her best friend John, who has been drawn into the mystery, join searchers scouring the countryside. But her attempts to unravel the McMillan family secrets have put Alex in danger, and she's not the only one.

Will the killer claim another victim? Or will the landscape reveal its mysteries to Alex in time?
