When an alien visitor discovers it can communicate with Earth’s oceans, it becomes the only intermediary between humanity and a vast marine intelligence whose patience with the human race is running out. Part survey, part discovery, the film explores a stretch of the wilderness that has largely slipped through the cracks of human attention, and in some places, bears the marks of human failure. The alien encounters a force both beautiful and terrifying, a voice as old as the planet itself, carrying memories, warnings and a power beyond human control. The film is a parable about nature on Earth by establishing an unidentified alien as interacting with the planet. By way of subtle messages the sea warns the alien that the existence of the planet is at stake. The alien discovers a controlling city but does not interfere with it and hopes that the sea will find a way to survive.
