On the eve of his planet's destruction, a scientist sends his son to Earth, where the baby is found and adopted by the Kents, who name him Clark. The boy soon learns that he has powers that other humans do not possess and determines that he will use them for good. Clark Kent grows up and moves to Metropolis, where he works as a mild-mannered newspaper reporter, moonlights as the caped hero known as Superman and is tested by the evil Lex Luthor who plans to kill him and take over the world.
