Earl Jenkins claims that his violent shaking disease was a result of illicit experiments on Level 3 of Luthorcorp. Lionel denies that it exists, so Earl takes a plant tour group hostage. Lex offers himself in exchange for the hostages.

Clark and Chloe discover that Titan, another alien escapee from the Phantom Zone, is the hulking star of a secret fight club whose bloody, bare-knuckle battles to the death are broadcast on the Internet. Lois smells a story and investigates on her own but is captured by fight manager-presenter Maddox, the Belle Reve administrator, and forced to become wrestler Athena's first opponent. To save Lois, Clark reveals his ability to catch bullets to Maddox so he can fight Titan, but is stunned to face Lois in the ring instead... Lana returns from her honeymoon with Lex, whose men are looking for Titan, but she's more uncertain about living the life of wealthy and power and has trouble with her pregnancy.
