Superman declares his love for Lois and his wish to spend his life with her. After conferring with the artificial intelligence of his mother Lara, Superman removes his superpowers by exposing himself to red Kryptonian sunlight in a crystal chamber, becoming a mortal. Clark and Lois spend the night together, then leave the Fortress and return from the Arctic by automobile. Arriving at a diner, Clark is assaulted by a truck driver named Rocky. Meanwhile, Zod and his cohorts, after becoming accustomed to Earth, travel to the White House and force the President of the United States to surrender on behalf of the entire planet during an international television broadcast. When the President pleads for Superman to save the Earth, General Zod demands that Superman come and "kneel before Zod!" Clark and Lois learn of Zod's conquest and, realizing that humanity alone cannot fight Zod, Clark tries to regain his powers. Lex Luthor escapes from prison with Eve Teschmacher's help, leaving his accomplice Otis behind. Luthor and Teschmacher infiltrate the Fortress of Solitude before Superman and Lois arrive. Luthor learns of Superman's connection to Jor-El and General Zod. He finds Zod at the White House and tells him Superman is the son of Jor-El, their jailer, and offers to lead him to Superman in exchange for control of Australia. The three Kryptonians ally with Luthor and go to the offices of the "Daily Planet". Superman arrives, after having found the green crystal that restores his powers, and battles the three. Zod realizes Superman cares for the humans and takes advantage of this by threatening bystanders. Superman realizes the only way to stop Zod and the others is to lure them to the Fortress. Superman flies off, with Zod, Ursa, and Non in pursuit, kidnapping Lois and taking along Luthor. Upon arrival, Zod declares Luthor has outlived his usefulness and plans to kill both him and Superman. Superman tries to get Luthor to lure the three into the crystal chamber to depower them, but Luthor, eager to get back in Zod's favor, reveals the chamber's secret to the villains. Zod forces Superman into the chamber and activates it; however, Superman crushes Zod's hand and tosses him into a crevice. Luthor deduces that Superman reconfigured the chamber to expose the trio to red sunlight while Superman was protected from it. Non falls into another crevice when trying to fly over it and Lois knocks Ursa into a third.
