Having returned to Smallville after his harrowing sojourn in Metropolis, Clark (Tom Welling) is confronted with a new peril in the form of a homicidal teenager. Determined to avenge his father's death, the young vigilante has been hunting down and murdering all "meteor freaks" -- that is, all those who have been altered by the power of Kryptonite rocks. Knowing that Lex Luthor (Michael Rosenbaum) is the next victim on the killer's list, Clark rescues Lex, thereby exposing his own powers -- and his own vulnerabilities -- to the relentless killer.
