A couple of porcelain cats live in a world that has become one big desert. The mother desperately hunts for something to feed her
kitten, but all she finds are remains of useless materials. Given the dreadful hardship of the situation, the only option that seems to make sense is to look for a way out and travel to a better planet. It is only then that she realizes that escaping will be just as difficult; if her living conditions are tough now, leaving for somewhere else will be even tougher.
