Clark and Lois meet Smallville's newest arrival face-to-face, and she has some surprising news. Clark decides to leave Smallville and continue with his superhero training but Jor-el informs him that a new Kryptonian menace has arisen.

Kara takes to life in Smallville by getting a job at the Talon, and entering the Miss Sweet Corn Pageant as a contestant, overruling Clark's objections. However, Lex takes an interest in her and three of the other contestants discover she has super-powers and decide to use her to steal a valuable time capsule.

When a movie is shot in Smallville, Clark is forced to secretly use his powers to save someone from a runaway car... but somebody is looking and becomes Clark's biggest fan. Meanwhile, Lionel's fate is revealed.

Lana absorbs Clark's powers during a lightning storm, which she uses to break into Lex's safe and steal some incriminating evidence. After being turned away by Grant at the Daily Planet, who won't accept her stolen evidence, Lana goes after Lex herself. Clark tries to rescue Lex, but must first battle the super-powered Lana.

Clark hears his mother's voice trapped in Kara's crystal, and releases her. She gives him Jor-El's ring made of Blue Kryptonite, which strips him of his powers.

A mysterious man who claims to be a product of Lex's latest project plants a bomb on Chloe and uses her to force Lois to get the truth from Lex.

Chloe begins to notice that Clark's not acting like himself. Bizarro enlists the help of Brainiac.
