An Australian couple sets off on a weekend to the coast in this psychological thriller. Peter (John Hargreaves
) and Marcia (Briony Behets
) are at each other's throats from the moment they pull out of the driveway, as Peter sneaks his dog along for the weekend and Marcia is harboring anger about a recent tragedy the couple faced. As day turns into night and they have yet to reach their destination, Peter hits a kangaroo while falling asleep at the wheel. This sets in motion a chain of mysterious events, which starts with them leaving the beaten path and appearing to go in circles through the darkened thickets of trees -- even though they've driven straight ahead for hours. Upon eventually reaching their destination, the strange happenings continue, with animals behaving in unusual ways, and a persistent cry of anguish floating over the water, which sounds almost human. Peter and Marcia are determined to prove they can rough it, even as they start to wonder if they've gotten in over their head. They doggedly remain camped, despite mounting evidence that they don't understand the feral Australian woods as well as they think.
