The film is set in a post-apocalyptic world, where a young girl named Hatsuko, living in a remote village, discovers a mysterious egg that contains a being who may be the key to humanity's salvation. As the story unfolds, Oshii masterfully weaves together elements of science fiction, fantasy, and mysticism, creating a dreamlike atmosphere that is both haunting and mesmerizing. The narrative is deliberately slow-paced, allowing the viewer to absorb the eerie and desolate environment, and to reflect on the themes and symbolism presented.
