This environmental thriller tells the story of Pan, a young woman with a mundane job which involves sorting and deleting sound files from before the crash. She unwittingly uncovers a collection of 21st century recordings which document the sounds of the rainforest, an eco-system which no longer exists. Pan seeks to discover what the rainforests were and what became of them, and in doing so has to escape the oppressive power of The Hands, whose job it is to keep the past in the past.
