If the world's most powerful computer can control even Superman...no one on earth is safe.
Aiming to defeat the Man of Steel, wealthy executive Ross Webster hires bumbling but brilliant Gus Gorman to develop synthetic kryptonite, which yields some unexpected psychological effects. Between rekindling romance with his high school sweetheart and saving himself, Superman must contend with a powerful supercomputer.
