Lex (Michael Rosenbaum) teams up with three krypto-villains to lure Clark (Tom Welling) to the hospital to enlist his help in escaping after he hears that Lionel (John Glover) has requested Lex be given electroshock therapy to erase his memory. However, the plan goes awry when the villains double-cross Lex and use kryptonite to steal Clark's powers. Meanwhile, Lana (Kristin Kreuk) meets a mysterious new stranger (Ian Somerhalder, Rules of Attraction) in the hospital.
