After years of facing megalomaniacal supervillains, monsters wreaking havoc on Metropolis, and alien invaders intent on wiping out the human race, the world's most famous superhero, Clark Kent, and comic books' most famous journalist, Lois Lane, face one of their greatest challenges ever: dealing with all the stress, pressures, and complexities that come with being working parents in today's society. Following a tragedy, Clark and Lois return to Smallville to handle some Kent family business. There, they reunite with Lana Lang and her husband, Kyle Cushing, while their twin sons, Jonathan and Jordan, adjust to life as teenagers in a small town. Complications arise when secrets about the boys' potential inherited Kryptonian powers come to light, and adversaries like the mysterious stranger Captain Luthor and the criminal mastermind Bruno Mannheim threaten their peaceful new existence.
