Four friends, walking home in a quiet Australian town, stumble across an unsettling sound in the trees. It's a laughter, but not a joyful one. It sounds like a little girl—until one of them sees something white, a figure, hiding behind a tree. What begins as a harmless curiosity quickly transforms into a chilling fear, creeping up on them like a shadow. The figure returns, but only to the naked eye. Cameras fail. Logic falters. And one by one, they realize they may not have been the first to see it.
