Mac Johnson never thought he'd be stranded in the mountains of Eastern Europe. But that's exactly what happened when his plane was shot down by Nazi ground troopers, leaving him and his four fellow Marines alone in the woods. Or so they thought. Because when one of the Marines disappears, Johnson will lead a search that causes him and his team to come face to face with a being that belongs in the darkest corners of hell. It's watching them. Stalking them. Hunting them. And it won't stop until every single Marine is dead.
