Superman (Brandon Routh), who has always wanted to find his roots, returned to Krypton, hoping to find other companions, but everything there no longer exists. And this trip lasted for 5 years. 5 years later, Superman returned to Earth, but everything around him had changed. He found that the Earth had become accustomed to not having Superman's protection. Louise (Kate Bosworth), whom he had always admired, won the Pulitzer Prize for writing a report on "Why the World Doesn't Need Superman". What broke his heart was that she was engaged to the editor-in-chief's nephew and was the mother of a 5-year-old child. On the other hand, his nemesis Lex (Kevin Spacey) used despicable means to defraud a huge inheritance and attempted to make a comeback. In Antarctica, Lex found clues about Superman's father and a crystal containing super energy, and wanted to use the power of the crystal to control the earth. Can Superman defeat his inner demons and save the earth from danger again?
