Catherine (Nicole Kidman) and Matt Parker are trying to adjust to their new life in the remote Australian desert town of Nathgari. They are pleasant but keep to themselves, unwilling to get close to anyone. On the eve of a massive dust storm, their lives are rocked when their two teenage children, Lily and Tom disappear into the desert. With Nathgari now eerily smothered in red dust and darkness, the locals join the search lead by local cop, David Rae (Hugo Weaving). It soon becomes apparent that something terrible may have happened to them.
Suspicion is cast, rumors spread and ancient Aboriginal stories are told in whispers as the locals begin to turn against the couple. With temperatures rising and the chances of survival plummeting with each passing day, Catherine and Matthew find themselves pushed to the brink, as they struggle to survive the uncertainty of their children's fate.
