In a post-apocalyptic world, humans rarely visit the “topside”. One day, a young boy that dreams of flying visits the topside to start building a plane. There, he meets a mysterious girl named Kud who is trying to rebuild a tower. Kud doesn’t say much, and she gives the people she meets strange names, and starts to call the boy “Plane,” while her friend that repairs electronics is “Radio”. This is their story of them traversing through their world.
