While looking for a birthday gift for Martha at a local jewelry store, Clark intervenes when two thieves try to rob the place using the powerful scream of Nathan Dean (Micah Alberti), a meteor-rock mutant with the ability to project ear-splitting screams. The combination of the scream with a bijouterie of kryptonite deflecting Clark's heat vision back to his face makes Clark blind. Without this sense, his hearing uncontrollably increases. One of the criminals, Masterson (William MacDonald) is arrested. Nathan kidnaps Pete to force his mother, Judge Abigail Ross (Felecia M. Bell), to release Masterson. Meanwhile, the blind Clark listens to a phone conversation between Chloe and Lionel Luthor about Lex and himself. After Clark informs Lex about his father's intentions for them, Chloe is mistakenly taken as Lex's informer and she gets fired from her intern job at the Daily Planet by Lionel.

The Smallville High cheerleaders are using a kryptonite mixed love potion to seriously change the behavior of their victims.

Alicia Baker returns, and with the help of Red Kryptonite, elopes in Las Vegas with Clark. Lana offers a sexual relationship to Jason in an attempt to win him back. Lionel comes back to Lex with a peace offering.
