A lonely widow, a sinister act, a remote mansion with a dark past ... After the violent death of her husband, Callie Jones retreats to a cottage in the grounds of an old mansion in Tasmania. The relative remoteness of the place and the wild beauty of the Tasmanian landscape are a balm to her shattered nerves and the locals seem friendly, particularly horseman Connor Atherton and his siblings at the nearby property, Calico Lodge. But all is not well: the old mansion has a sinister past, one associated with witchcraft and murder. As Callie is threatened by odd events in the night and strange dreams overtake her sleep, she begins to doubt her own sanity. What's really going on beneath the surface of this apparently peaceful town? Are her friends and neighbours really who they seem? As events escalate, Callie starts to realise that the mansion may hold the key to unlocking the mystery, but the truth might have as much power to destroy as it does to save.
