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.
The story begins on a small spaceship docking with a refueling station. On board are a group of four aliens, Bernard, Sandra, Desmond, and Julian. During a particularly tedious period of their stay at the station, the other three begin playing with the ship’s controls while Bernard is outside playing spaceball. They accidentally disconnect his part of the ship, leaving him stranded while they crash into a large blue planet close by (Earth).
