A group of international tourists embarks on an Outback adventure of a lifetime. Overnight, their driver is suddenly replaced without notice by an affable, if slightly strange, new tour guide.

Waking up to find themselves in the middle of nowhere with no driver in sight, and the coach's power and comms down, the group begins to realise that their holiday has become a desperate bid for survival.

Dealing with a traumatic turn of events and realising they are being targeted by Mick Taylor, the group makes its way towards a hill in search of missing comrades, water and civilisation.

Still reeling after a tragic passing, the group's desperation reaches new heights when Nina is bitten by a snake. Meanwhile, as she searches for Steve, Kelly is finally able to confront Mick.

The survivors find a mothballed mine occupied by an eccentric caretaker and his family. Elsewhere, Mick unhappyly presses one of the lost tourists for the group's location.

The survivors stumble on the location of Mick's deepest, most awful secrets. But Mick is hot on their heels, and he's mad as hell.
