Penelope, her younger brother Charlie, and their dog Mickey were just out for their usual late-night stroll-a quiet routine before bed. But when Mickey suddenly breaks free and darts into the woods after something unseen, their peaceful evening takes a terrifying turn. Charlie chases after him without thinking. Penelope, fearing for them both, follows. But the deeper they go, the darker the forest becomes-and it's not just the shadows or trees that are watching.
