Deep in the Australian countryside, a reclusive community hides a deadly secret.
Life is falling into place for National Parks ranger Erin Taylor. She has a job she loves, she's falling for her colleague, Simon - and she is finally leaving the past behind. Until a woman is murdered.
But the victim is not just any woman - she's Simon's wife, Hayley. The wife he's not mentioned to Erin. The wife he's not seen in fourteen years. On the edge of the national park, the alternative lifestyle community of 'Simple Bliss' denies knowing Hayley, but Simon and Erin suspect otherwise.
As Simon uncovers shocking details about the group, Erin is drawn further into their midst and finds a web of lies, decades old - and a charismatic, manipulative, dangerous cult leader who will let nothing and no-one stand in his way. On the wrong side of a river in flood that has become a lethal torrent, Erin and Simon must race to expose the truth and prevent a tragedy.
