When Clark (Tom Welling) discovers Lionel (John Glover) threatened to kill him unless Lana (Kristin Kreuk) married Lex (Michael Rosenbaum), he goes after Lionel to silence him once and for all.
Lana tells Lex she is leaving him, and Martian Manhunter (guest star Phil Morris) makes a return appearance to help Clark stop Lex, who is trying to find the last wraith from the Phantom Zone in order to use its DNA to power his army of super soldiers.
Meanwhile, Lois (Erica Durance) goes to Reeves Dam in search of information about Lex's secret lab and is brutally stabbed by a security guard. Chloe's (Allison Mack) secret power is revealed.
