Three years after the mysterious disappearance of his family on a routine camping trip to the Grampians National Park, Ian Linville finally opens up to investigative reporter, Mueller, about the shocking truth of what really happened.

A warning from Park Ranger, Martha Jacobs, puts everyone on edge and when Sarah and Aaron shoot a Yowie in the bushes, it's not at all what they expected.

Sarah's secret forces her to convince Ian and Aaron to dump the body, but when a near collision forces them into an unexpected Yowie manhunt, their dead body goes missing and they must find it at all costs.

When Aaron suffers an asthma attack while evading the Ranger's search party, Ian is separated from them by a surprise Yowie ambush. Outmatched by their supernatural abilities and ultimately left for dead, Ian loses his family forever and Mueller's true identity is finally revealed.

Breaking evidence in the three year case helps Mueller to sieve fact from fiction in Ian's story to discover the real horrific truth. Besieged by anger and revenge, Ian and Mueller erupt into an ultimate showdown with dire consequences that reveals a true monster inside one of them, in this epic chilling conclusion.
