Smallville

Over a decade ago, a meteor shower brought destruction to the unsuspecting citizens of Smallville, Kansas. Since then, strange events have occurred, apparently because of the meteorites, which accompanied a spaceship carrying a toddler who grew into a teenager, Clark Kent (series star TOM WELLING), in the care of his adoptive parents, Jonathan (series star JOHN SCHNEIDER) and Martha (series star ANNETTE O'TOOLE) Kent. Jonathan, Martha and Clark carefully hide the fact that Clark possesses unearthly powers, even from his best friends and classmates Chloe Sullivan (series star ALLISON MACK)--the intrepid investigative reporter for the Smallville High Torch--and straight-talking Pete Ross (series star SAM JONES III). Clark struggles with his feelings for both the beautiful girl next door, Lana Lang (series star KRISTIN KREUK), and the more receptive Chloe.

Clark goes into hiding after he discovers his startling new power that quickly gets out of control and accidentally harms Lana. Meanwhile, a sexy new teacher, Desiree Atkins (KRISTA ALLEN), uses meteor-enhanced pheromones to convince Lex to marry her and then spellbinds Jonathan. Clark must learn how to control this new ability in time to prevent Jonathan from killing Lex.

After one of his friends discovers Clark's spaceship in the cornfield, Clark defies his parents' wishes and reveals his secret to the person--who gives him a shocking reaction. Meanwhile, Lex clashes with one of his scientists, Dr. Steven Hamilton (recurring guest star JOE MORTON).

When the school unwittingly uses red meteor rocks in its class rings, Clark experiences a new meteorite effect: Stunning his friends and family, he becomes a rebellious and dangerous teenager who uses his powers for malevolence instead of good. Jonathan and Martha scramble to find an explanation for Clark's behavior before he exposes his true identity to the world. Meanwhile, Lana is drawn to the "new" Clark, who openly declares his love for her.

Clark becomes concerned when a mysterious poet, Byron Moore (SEAN FARIS), leaves love notes for Lana at her parents' grave. Clark warns her to stay away from Byron, but she is intrigued. After a mishap, Clark and Lana befriend the elusive boy and find out that he sneaks out of his house, where his parents keep him locked up in chains. They become determined to save Byron--but he has a dangerous secret.

Because the farm is in financial trouble, Martha asks her estranged father, William Clark (GEORGE COE), for help. Clark is thrilled at the prospect of meeting his grandfather, but Clark's forced reunion doesn't go as planned because of an argument between Jonathan and William. Meanwhile, Lana discovers an old photograph that suggests her father may still be alive.

A mysterious woman, Rachel Dunlevy (BLAIR BROWN - "The Days and Nights of Molly Dodd"), visits the Kents and claims to be Clark's mother, prompting them to finally tell Clark what happened after they discovered him in the cornfield that fateful day. Clark learns why his father hates the Luthors, how his adoption was arranged--and who else has rescued Lex from death.

Clark tests the limits of his powers to save his young telepathic friend, Ryan (recurring guest star RYAN KELLEY), from an evil doctor who wants to control the boy's abilities. Meanwhile, Lana's aunt and guardian, Nell (recurring guest star SARAH-JANE REDMOND), tells Lana that she plans to move the family to Metropolis.

When Clark tries to warn Lana and Chloe about Ian (JONATHAN TAYLOR THOMAS - "Home Improvement," "Wild America"), an overachieving student who is surreptitiously dating both girls, they accuse Clark of jealousy. But Lana and Chloe realize too late that Clark was right. Meanwhile, frustration with his father causes Lex to become enraged and attack a parking officer's car with a golf club. Forced to attend anger management class, Lex meets an interesting woman, Dr. Helen Bryce (recurring guest star EMMANUELLE VAUGIER - "My Guide to Becoming a Rock Star").

While dirt-biking with Pete, Clark falls into a cave and discovers two hidden treasures: ancient Native American inscriptions that hold the key to his identity and a beautiful girl whom he believes to be his soul mate. Desperate to preserve the writings, Clark pits father against son by enlisting Lex's help in stopping Lionel's construction crew from demolishing the cave.

Whitney Fordman (former series star ERIC JOHNSON) returns home from a tour of duty with the Marines, hoping to renew his relationship with Lana. However, Whitney's suspicious behavior prompts Clark to question his friend's motives--ultimately revealing a shocking truth. Meanwhile, Lex distrusts his new girlfriend, Dr. Helen Bryce (recurring guest star EMMANUELLE VAUGIER), after he finds a photograph of her with Lionel.

After discovering that Lionel has secretly installed video cameras in the mansion, Lex hires thugs to put surveillance devices in Lionel's Metropolis office. However, the situation gets out of control when Lionel and Martha surprise the interlopers and are taken hostage. Desperate for a way to save his mother without exposing his powers, Clark must access the office from an adjacent tall building--if he can make the leap in a single bound.

After Lionel is shot and wounded, Jonathan is arrested. But Clark and Pete perform their own crime scene investigation and realize that more than one person had the opportunity and motive to harm Lionel--including Lex. Meanwhile, Lana becomes suspicious when her lawyer father, Henry (recurring guest star PATRICK CASSIDY), mysteriously refuses her request to defend Jonathan.

After a parasitic worm infects Pete and Chloe, they become thrill-seeking daredevils, and Pete uses red meteor rocks to persuade Clark to join them on a dangerous adventure. Not only does Clark display his powers, he also kisses Chloe--as witnessed by a stunned Lana.

Lex finds Lucas (PAUL WASILEWSKI), the son Lionel gave up for adoption, and brings him home in the hope that they can unite against Lionel. But when Lionel's machinations put all three of them in a dangerous situation, Lex is left to wonder whom he can really trust. Meanwhile, Clark decides to take a job at the Talon.

Martha is seriously sickened by meteor dust, and Clark and Jonathan desperately try to help her. But when Clark becomes infected as well, he finds out just how vulnerable he can be. Only a miracle can save Clark and his mother--and the amazing secret she holds within. Meanwhile, Lex confronts his feelings for Helen (recurring guest star EMMANUELLE VAUGIER) as she considers an enticing out-of-town research position. And Chloe and Lana cope with the unthinkable possibility that they may lose Clark forever.

Determined to find out where he came from, Clark travels to New York to meet Dr. Virgil Swann (CHRISTOPHER REEVE - "Superman" movies), a brilliant scientist who possesses a message for Clark from his home planet. Meanwhile, Lana decides to move out of Chloe's house--and into the Luthor Mansion--after the two girls get into another argument about Clark.

After his schoolmate, Cyrus Krupp (JEREMY LELLIOTT), claims to be an alien and seemingly proves it by using heat vision, Clark investigates and begins to believe that the boy is from Clark's home planet, Krypton. Meanwhile, when Helen (recurring guest star EMMANUELLE VAUGIER) discovers a locked room in the Luthor mansion, she demands to know what is inside--and Lex must decide whether or not to admit the truth about his ongoing investigation of Clark.

After Lana is almost assaulted by a college student, Clark loses control and injures him. The Kents are then sued for punitive damages that could cost them the farm, and Clark questions his powers--while trying to find a way to forestall the lawsuit. Meanwhile, Helen's ex-boyfriend arrives in town intent on winning her back. When she rebuffs him, he stalks her, prompting Lex to take action.

Clark inadvertently witnesses the robbery of a LuthorCorp truck carrying kryptonite and is stunned to realize that he can't stop the thieves--they are as strong as he is. To keep Clark from telling the police, the thugs attack Jonathan and Martha, leaving Clark feeling powerless and desperate for a way to protect his parents.

After Lana is visited by the ghost of her childhood friend, she turns to Clark for help in uncovering the truth about the strange visitor. However, Clark realizes that the little girl is actually a kryptonite-enhanced clone, and he rushes to save Lana before the revenge-seeking child harms her. Meanwhile, Lex learns that Lionel is funding the cloning research.

When Dr. Fredrick Walden (recurring guest star ROB LaBELLE), the famed linguist who was injured while studying the caves, awakens suddenly from a coma, he possesses fantastic powers and goes on a dangerous mission. Meanwhile, Lana helps Clark celebrate his "birthday" in a very special way. Lex and Helen endure doubts and stress while planning their wedding. And Lionel forges a surprising alliance with Chloe.

In the season finale, Clark makes an astonishing discovery about his origins--and faces the choice of his lifetime. Meanwhile, Clark and Lana agonize over a rift with Chloe. Lionel comes closer to solving the mystery of the cave writings. And Lex and Helen's wedding becomes a much more dramatic event than anyone envisioned.
