A child climbs out of a wrecked car, picks up a turtle, and sets off on a long walk against the backdrop of the setting sun. Along the way, she explains to the turtle the origin of humankind. Meet Moon – a girl wandering around the post-apocalyptic world where adults no longer exist, and the remnants of the old world have become a playground for children. The young inhabitants of this world spend their days learning mysterious rituals rather than mathematics, ways of communicating with animals, and the art of survival; their games resemble rites.
