Synopsis:
A Kryptonian man and his son visit a valley when deadly trails of smoke permanently litter the sky. 2000 years earlier, inventor Dol-Nd has discovered rare crystals which contain great energy. He uses the crystals to power mechanical wings which he has invented, enabling him to fly. However, the wings emit a trail of smoke which remains in the sky after their use. The trails are permanent and deadly to all life with which they come into contact. An escaped murderer sees Dol-Nd testing the wings and steals them, creating more deadly trails in the process. Dol-Nd leads the criminal to his doom, then destroys the wings to prevent further pollution of the skies.
