TOXIC WASTE – A LuthorCorp experiment is released into the atmosphere – a toxin that causes its victims to hallucinate their worst fear. Chloe (Allison Mack), Clark (Tom Welling), Lana (Kristin Kreuk), and Jason (Jensen Ackles) all fall victim to the toxin, and Lex, desperate to find a cure, takes a dangerous antidote. Meanwhile, Lionel (John Glover) is released from prison and his conviction overturned thanks to a mysterious benefactor.
