When a young couple misses the final ferry off a remote island, they figure they’ll just make the best of a quiet night under the stars. But as darkness falls, the island’s true nature reveals itself. Something ancient and malevolent prowls the woods—something that doesn’t take kindly to intruders. Trapped with no way off until morning, the couple must survive a night of relentless stalking and mind-numbing fear, as a Dogman makes it clear they were never meant to be there.
