Without the approval of his father, Clark kicks off senior year by trying out for the Smallville High Football Team, who are now coached by Lana's new boyfriend, Jason Teague. Former acne-ridden nerd Abigail Fine returns from the summer looking beautiful after some Kryptonite powered plastic surgery that spells trouble for Lana and a former tormentor when Abigail discovers that the side affect makes people insane and delusional to anyone she physically kisses. When Lois investigates Abigail's history, her ruthless, plastic surgeon mother, Dr. Fine, decides to silence the curious but klutzy Lois by enforcing the surgery on Lois. Meanwhile, Martha accepts a job managing The Talon while Lois starts working for the school paper the Torch, and gets just a little closer to Clark.

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

A mysterious bookie with powers of manipulation has a strange, even dangerous, effect on Clark and his friends. Meanwhile, Lex causes friction by using his influence on Jason and Lana's relationship.
