When Clark Kent (series star TOM WELLING) confronts Bizarro, the last wraith from the Phantom Zone, the ensuing fight causes the dam to break, unleashing a torrent of water. Having just been arrested for Lana Lang's (series star KRISTIN KREUK) murder, Lex Luthor (series star MICHAEL ROSENBAUM) is submerged under water in a patrol car until a mysterious young woman saves him. Lois (series star ERICA DURANCE) manages to pull Chloe (series star ALLISON MACK) to safety, but Chloe is pronounced dead at the hospital. And the woman who saved Lex reappears at the Kent farm. Series star AARON ASHMORE appears as Jimmy Olsen, and series star JOHN GLOVER appears as Lionel Luthor.

Lois follows Lex to Detroit and discovers he has found Kara, who has amnesia. However, Finley (guest star COREY SEVIER - "House of Fears," "North Shore"), a busboy who has become obsessed with Kara, fears Lex will take her away, so he shoots Lex and holds Kara and Lois captive. After finding Lex's comatose body, Chloe offers to heal him, but Clark refuses to let her.

A camera crew of a reality series follows the CSI team during the first 48 hours of an investigation involving an upscale real-estate agent found dead in her glamorous high-rise apartment.
