Unique sound-generated visual effects and special effects using a blue screen, a rotoscope, pyrotechnics, computer graphics, and matte photography create a futuristic, space-fantasy drama for children. A boy and girl from a space-roving civilization of the distant future become trapped in the gravity web of a wizard, the sole inhabitant of a dead star. As the story evolves, the youngsters realize that the wizard, in his own way, is also a prisoner. A conflict between the protagonists leads to the wizard's discovery of music and harmony, which ultimately prove to be the keys that spring the trap.
