Clark discovers a cave that may hold the key to his identity and his soulmate. He asks Lex for helping fighting Lionel Luthor's proposed constuction that would destroy the cave.

The intro: Native American Joseph Willowbrook objects to building on the site of a new office park funded by LuthorCorp. As the construction foreman fuels his SUV at the site, he hears rustling in the bushes. He shoots of a flare as a white wolf attacks. The wolf runs off to watch from a safe distance, before the flare comes down, igniting the leaking gas and causing an explosion.

Who is Kyla? While riding motocross with Pete near the construction site, Clark falls into a cave. A beautiful Native American girl, Kyla finds Clark unharmed. She is in the cave doing research for her grandfather, Willowbrook. Clark's fall has uncovered ancient drawings. The drawings tell the prophecy of Naman, who will fall from the sky in a rain of fire, have the strength of ten men and will be able to start fires with his eyes. As they leave the cave, Clark notices an octagonal impression in the wall that matches the size and shape of his spaceship's key.

What's up with Clark? Clark is convinced the legend tells his story. Clark invites Kyla and her grandfather to dinner at the Kent's. Willowbrook relates the 500-year-old legend that tells of a man who came from the stars and fell in love with the "mother" of Kyla's people. From their affair, Kyla's people were born. The man left earth, promising to send another after him. Clark asks Martha to ask Lionel to preserve the sacred caves so Kyla's grandfather can continue to study. In the barn, Kyla tells Clark more about the legend of her people, pointing out a constellation tracing a wolf's head.

One star, the eye is missing. Kyla says the missing star is where Naman came from. As Kyla and Clark get closer, Lana appears in the barn. Clark had left her an urgent message about the caves. Clark asks Lana to ask Henry Small if he would defend saving the caves. Later while Clark and Kyla explore the caves, Kyla interprets more drawings. Someday, Naman will protect the entire world. A pictograph of a beast that is like a brother to Naman, turns against Naman, but the two would be the balance between good and evil. There is also a drawing of the woman Naman is destined to be with. There is a symbol beside her…the same design that is on a turquoise bracelet worn by Kyla. Just then, construction above causes a boulder to fall. Clark covers Kyla to protect her. She realizes he is Naman, accepting Clark's differences. Clark admits there are a lot of things about himself he can't explain. They kiss.

What's up with Lionel? Lionel tells Martha that Joseph Willowbrook has been involved with past protests, and is being investigated about the explosion at the construction site. Lionel tells Martha she reminds him of his wife and her honesty. Lionel compliments Lex on the business successes he has accomplished without him, and asks him to join him in the office park construction. Lex refuses.

What's up with Lana? Henry Small talks to Lana at the Talon. He tells her the DNA tests are positive, he is her father, and wants to earn that place in her life.

What's up with Lex? At protests on the construction site, Martha asks Kyla's grandfather Mr. Willowbrook to meet with Lionel. He refuses, not trusting Luthor. Henry Small shows up with a cease and desist order for the construction, based on discoveries in the cave. The sheriff arrives to arrest Willowbrook for the murder of the construction foreman, based on a bloody towel found in Willowbrook's trash. Willowbrook tells Martha Luthor is framing him. Clark visits Lex with accusations against Lionel, trying to raise bail money for Willowbrook. Lex questions Clark about Kyla and Lana, suspecting Clark's passion. Lex refuses to help him with bail money, but Clark wants to convince him. Clark takes up activism to raise money to save the caves. Clark shows Lex the pictographs in the caves. Lex sees the octagon impression, and knows the importance of the cave paintings, giving the money for Willowbrook's bail.

What's up with Chloe? Chloe's investigations uncover the foreman's autopsy, showing teeth marks from a wolf, no longer found in Smallville. Chloe also finds out that the Kawatche tribal name translates into "Skinwalkers." She gives Clark information about a Native American myth says that humans can transform into animals. Clark insists Willowbrook is not a murderer.

What's up with Martha? Martha again tries to smooth over bad feelings of Willowbrook towards Lionel. Willowbrook tells her he realizes where her allegiances are, and leaves with Kyla. Later, at night as Martha leaves LuthorCorp, she hears rustling, and hurries to her car. Just as she gets in, the white wolf jumps to snarl and threaten at her windshield. Nervously, she starts the car. When she looks up again, the wolf is gone.

What's up with Jonathan? Clark admits his feelings for Kyla to Jonathan. Clark can be himself with Kyla, he feels like she's his destiny. Clark also says he's uncertain whether Kyla's being honest with him, and that she knows about the foreman's death.

How it ends: Lex offers to buyout Lionel's office park project, dollar for dollar, to preserve the caves. Lionel suspects another motive. Clark questions Kyla about skinwalkers. Kyla says legends connect the visitor from the stars who brought green space rocks. The rocks had effects on the people, towards human - animal transformations. Clark asks if Kyla's grandfather is a skinwalker. He tells of the attempted wolf attack on Martha.

Kyla leaves, hurt and offended by the accusations. Meanwhile, Lionel hears scratching on the door of the mansion, and wolf howls outside. The white wolf appears in his study, threatening and snarling in attack. Clark arrives in time at the door. Clark calls out "Joseph!" The wolf stops its attack, as Clark stares into its eyes. The wolf jumps from the window. Clark follows outside, finding the white wolf injured. The white wolf transforms into Kyla. He rushes to comfort her. She says she didn't want to hurt the foreman or Martha. She didn't tell him her secret because she was afraid. Before she slips away, Kyla apologizes, saying she's sorry she can't be the one for him, Naman. The next morning at the construction site, Clark stands in front of the bulldozers. Martha and Lionel arrive. Martha says she believes in Clark. Lionel threatens her job security. She goes to Clark anyway. Willowbrook and his people arrive, thanking Clark.

Willowbrook says Kyla had faith in him, and so does he. He gives Clark Kyla's turquoise bracelet, for the "True one in your life." Lex tells Lionel he should've taken his offer on the land. Now the state has exercised historic preservation on the land, buying Lionel out at 30 cents on the dollar. Lex's company LexCorp has the contract for the preservation of the area. Lionel tells Lex he knows there is something valuable in the caves, and whatever it is, he'll find it. Lex goes back into the caves, examining the octagonal impression. Lana visits Clark in the barn, expressing her sympathy for Kyla. Lana is upset. She tells Clark Whitney is missing in action. Clark comforts Lana as she cries.
