In a futuristic society, an old man tells the legend of a strange medal to two children. In flashback, we learn that after a nuclear catastrophe, two teenagers were living in an artificial paradise, maintained by electronic means, and once decide to leave that shelter and escape using that same medal - a mini video-disc - in search of outer-space freedom.
