The residents of Smallville are thrilled when "Warrior Angel," a movie based on a comic book, begins shooting in town. However, after the lead actress, Rachel Davenport takes off in stunt car with cut brakes, Clark must step in to stop the runaway car. Unfortunately, an obsessed fan witnesses this heroic event and decides Clark is a real life superhero, whose girlfriend Lana must be eliminated so Clark can fulfill his destiny. Meanwhile, Lex discovers Lionel at the cabin.

As Christmas draws near, Lois receives a call from an anonymous man claiming that Chloe is attached to a bomb, and the only way he won't let it blow is if she reports the truth of Lex's atrocious experiments about the mysterious 33.1. Lois tries to find a way on her own to stop the mysterious person who is linked to both Lex and Grant Gabriel. Chloe and Jimmy end up getting stuck in an elevator at the Daily Planet with the bomb ticking, prompting Chloe to reveal her secret meteor-rock power of healing to him. Meanwhile, Clark returns from his enforced imprisonment from the Fortress of Solitude. With Kara still missing, Clark uncharacteristically wants Lana to re-open her Isis program of spying on Lex with the intent of taking him down, and wants to become closer to Lana when he has been distancing himself from her. But what exactly does 'Clark' have in mind?

Pete Ross returns to Smallville and finds a number of surprising changes since his departure four years earlier. Besides resolving his feelings toward Clark since he learned of his friend's secret, Pete has to deal with the acquisition of a superpower of his own: that of his ability to 'stretch' his body courtesy of kryptonite-laced gum he's been chewing and consuming for nearly a year. Meanwhile, Lex continues to sow seeds of anxiety into the amnesiac and powerless Kara over Clark as well as wanting to know about her past, as does Jimmy Olsen.

Lionel kidnaps Clark and holds him in a kryptonite-lined cell at a Luthorcorp facility; Chloe and Lana confront Lionel, who blames Lex, and they then take Kara to the Fortress and plead with Jor-El to restore her memory so she can save Clark.

When Brainiac ends up in a confrontation with Clark after trying to coerce Kara into joining him, he takes it out on Lana.

Despite his father's warning, Lex still finds himself in a power struggle from within over the secret to The Traveler...with some deadly results.
