The fourth and final season of Superman & Lois picks up with Superman and Luthor's monster locked in a ferocious, moon-wrecking battle, as Clark fights for his life against the seemingly unstoppable creature. Back on the ground, General Lane struggles to stay alive after being kidnapped by Luthor's henchmen, while Lois, Jordan, and Jonathan race against time to rescue him. But standing in their way is Lex Luthor himself, who has permanently moved to Smallville as the next step in his malicious plan to destroy Lois Lane.
