The great Australian dream is to spend the kids’ inheritance on a massive four-wheel drive and a gigantic caravan, then head to the outback to convince yourself you are having a good time.

Rex and Barbara Rogers set off on their adventure, embracing the dream, until a flat tyre leads to disaster. Now, they have vanished without a trace.

It is up to local police officer Ben Buckley and Bo Wirrapunda, a First Nations woman deeply connected to her land, to unravel the mystery of the missing grey nomads. As they search for answers, the outback reveals secrets far more dangerous than anyone could have imagined.
