Three escaped criminals from the planet Krypton test the Man of Steel's mettle. Led by General Zod, the Kryptonians take control of the White House and partner with Lex Luthor to destroy Superman and rule the world. But Superman, who attempts to make himself human in order to get closer to Lois, realizes he has a responsibility to save the planet.

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 in the third installment of the 1980s Superman franchise. Between rekindling romance with his high school sweetheart and saving himself, Superman must contend with a powerful supercomputer.

Superman agrees to sacrifice his powers to start a relationship with Lois Lane, unaware that three Kryptonian criminals he inadvertently released are conquering Earth.
