WHO SHOT LIONEL LUTHOR? – When Lionel is shot, Jonathan is arrested, but after Clark and Pete perform their own crime scene investigation, they realize that more than one person had the opportunity to kill Lionel – including Lex. Meanwhile, Lana is suspicious after she asks her father to take on Jonathan’s case and he declines for mysterious reasons.
Clark meets a Native American girl in a cave and discovers drawings on the walls from the girl’s ancestors that tell a tale mirroring Clark’s arrival in Smallville during a meteor shower. Meanwhile, Lana learns the results of a DNA test that could prove her kinship to Henry Small.
The plot continues to develop the show’s mythology, as Clark meets up again with Ryan, a teenage mind reader the Kents befriended last season. This time, Clark tries to protect the teen from a scientist who has been conducting cruel experiments on the boy. Meanwhile, Lex crosses swords with Smallville’s corrupt mayor over a potential business deal that could have serious ramifications for the town.
A strange woman arrives in Smallville and tells Clark that she’s his biological mother and informs Lex that Lionel is the father. And she wants Clark take a DNA test to confirm her story. Meanwhile, Lana decides to meet the man who could be her biological father.
A teen who is kept locked in the basement of his parents’ house during the day sneaks out at night and leaves love letters for Lana at her parents’ graves. Meanwhile, Lionel Luthor hires Clark’s mother as his personal assistant.
It appears that shrewd billionaire Lex Luthor has taken leave of his senses when he marries a woman he hardly knows. The new Mrs. Luthor is Smallville High School teacher Desiree Atkins, who has the ability to temporarily control a man’s mind by emitting a kind of pheromone mist. She and Lex wed shortly after they meet, and Desiree immediately sets out to steal the Luthor fortune by planning her transition from wife to widow. She tries to persuade Clark to murder her new hubby, but her powers don’t work on the Kryptonian so she’s forced to find another pawn. Meanwhile, Clark’s troubles aren’t over; he’s struggling with his latest gift—heat vision.
The adventures continue for the Teen of Steel as the drama kicks off its sophomore season with Smallville still in the grips of a devastating twister. Faster than a speeding bullet, Clark rescues Lana from the storm and rushes her to a hospital before he races home to aid his folks. But Clark soon discovers that his dad is missing and was last seen chasing a nosy newspaper reporter off the farm. Elsewhere, millionaire Lex Luthor has his own problems when his conflicted feelings for his father cause him to hesitate in a moment of crisis.
A head injury gives Lana the ability to see through the eyes of a kidnapper who abducts Chloe and keeps her bound and blindfolded in a dark room filled with giant teddy bears. Meanwhile, an ambitious newspaper reporter provides Lex with new information about the meteor shower.
Lex’s shady past catches up with him when a man he thought was dead turns up in Smallville. The trouble stems from an incident in Metropolis three years before, when Lex escorted a woman to the hot spot Club Zero to make sure she caught her fiancé in the act of cheating. The furious groom-to-be attacked Lex, and the encounter ended with a purportedly fatal gunshot. Now the supposed corpse reappears at the cafe that Lex is renovating and leaves him a disturbing warning: the recently amputated hand of a security guard who assisted Lex that night at the club. Meanwhile, Clark is unsettled by a school assignment that has Chloe probing into his past.
The Teen of Steel becomes mere flesh and blood in the aftermath of an ill-timed rescue attempt. While trying to save a classmate from falling off the edge of a dam during a rainy class trip, Clark grasps the student’s backpack, unaware that it is contaminated with Kryptonite. At the same moment, a bolt of lightning strikes, stripping Clark of his superpowers—and transferring them to the imperiled teen. Blessed (or cursed) with his newfound extraterrestrial abilities, the student sets out to win the heart of a popular girl, while Clark adjusts to life as a normal person.
Clark’s craftiness is tested in this intriguing installment when he matches wits with a corrupt Metropolis police detective. On his way back from viewing an art exhibition in the city, Clark stops an out-of-control bus from hitting a homeless man. His heroics are witnessed by a crooked lawman, who tracks down the Smallville teen and makes him an offer he can’t refuse: Perform illicit tasks for the cop or face exposure. But Clark isn’t so eager to capitulate. Elsewhere, Lex’s love life heats up when an old flame breezes into town and asks him to reconsider his current position in his father’s company.
An old Kent family friend, who suffers from uncontrollably violent convulsions after working for Luthor Corp., shows up on the farm after accidentally killing a man in Metropolis. Meanwhile, when Clark’s parents head to the city for a romantic getaway, the teen decides to host a party that soon gets out of hand.
While volunteering at a nursing home, he meets a blind resident who is rumored to be able to see the future. When Clark touches the woman’s hand, she warns her guest that someone close to him will die soon. The prediction so unnerves Clark that he asks his parents to leave the dangerous farm work to him. His fears become intensified when he visits the woman again and has his own vision of the gravestones of his family and friends. Meanwhile, another resident regains his youth after falling into a lake lined with kryptonite and sets out to settle an old score.
Clark battles intense headaches as he tries to adjust to his emerging power of X-ray vision, an ability that he cannot control. Also, Lex is framed for an armed robbery by a teenage girl who can take on the appearance of anyone she chooses. Elsewhere, Lana finds her mother’s journal and accuses her aunt of lying to her.
