Smallville

When Clark Kent confronts Bizarro, the last wraith from the Phantom Zone, the fight causes the dam to break, unleashing a torrent of water. Just arrested, Lex Luthor is submerged under water in a patrol car until a mysterious young woman saves him. Lois manages to pull Chloe to safety, but Chloe is pronounced dead at the hospital. And the woman who saved Lex reappears at the Kent farm.

Clark and Lois discover a spaceship belonging to Kara, the mysterious young woman who recently saved Lex. Clark decides that, without Lana, there is nothing keeping him in Smallville, so he heads to the Fortress of Solitude to begin his training. However, Jor-El tells Clark that he must stay in Smallville to find out why Kara really came to Earth. Meanwhile, Lex makes a stunning discovery.

Clark tells Kara (LAURA VANDERVOORT) to keep a low profile, but she signs up for the Miss Sweet Corn beauty pageant and meets the competition, three meteor-infected vixens who plan to use their powers to steal a treasure map to a hidden Smallville time capsule. After Tyler witnesses Kara using her powers, the girls pretend to be Kara's friends but plan to use her for their scheme.

Chloe learns that Dr. Curtis Knox (DEAN CAIN) is treating meteor-infected people and eliminating their abilities. Chloe makes an appointment to see Knox, unaware of his nefarious plan. Meanwhile, Kara (LAURA VANDERVOORT) cons Jimmy into helping locate her crystal and, after discovering its whereabouts, defies Clark's order to stay on the farm. And Lana sets up secret surveillance of Lex.

Warrior Angel, a movie based on the comic book, begins shooting in Smallville. However, after the lead actress, Rachel Davenport, drives off in a stunt car with cut brakes, Clark must stop the runaway car. Unfortunately, an obsessed fan witnesses this and decides that since Clark is a real-life superhero, his girlfriend, Lana, must be eliminated so Clark can fulfill his destiny.

Kara (LAURA VANDERVOORT) travels to Washington to search for the crystal, but she is captured and sedated with a Kryptonite-infused truth serum. The dose causes her to relive a prior trip to Earth when she followed Clark's biological mother, Lara (HELEN SLATER), to the Kent farm. Clark arrives in time to save Kara, but he also falls victim to the serum and sees his mother through Kara's memories.

During a lightning storm, Lana absorbs Clark's abilities. Using her newfound superpowers, she breaks into Lex's safe and steals incriminating evidence, which she delivers to Lois and Daily Planet editor Grant, demanding they run a story exposing Lex's secrets. After Grant refuses, Lana decides to take care of Lex herself. When Clark tries to stop Lana from killing Lex, a super battle ensues.

After hearing the voice of his biological mother, Lara, calling for help from Kara's crystal, Clark releases Lara. She gives him a ring of blue Kryptonite. But when Clark puts it on, he realizes that Zor-El has tricked him -- blue Kryptonite strips Clark of his powers. Meanwhile, Chloe and Lex each discover that Lois and Grant have been dating and warn them to stop.

Clark tells Lana that Kara is gone and that they should team up to bring Lex down, so she gives him information, including a report on a man named Adrian, who was infected with an alien substance. Adrian secretly plants a bomb on Chloe and tells Lois if she doesn’t get Lex to admit the truth about his experiments with 33.1, he will detonate it. Chloe confesses to Jimmy that she is a meteor freak.

While Clark is frozen in the Fortress, Bizarro takes over his life with Lana. Unaware that she is with Bizarro, Lana enjoys this “new Clark,” and shares information she gathered on a serial killer draining his victims of all trace minerals. The two conclude it must be Brainiac, and Bizarro sets off to find him. Lex is stunned at Lionel's reaction after Grant, reveals he is a clone of Julian.

While secretly working for Oliver (JUSTIN HARTLEY), Chloe intercepts one of Lex's project files, but she is attacked by the Black Canary (ALAINA HUFFMAN), a mystery woman with a subsonic cry. Dinah Lance, Black Canary’s alter ego, is a conservative talk show host who is working at the Daily Planet and clashes with Lois. Meanwhile, Lois discovers Oliver's secret.

Lois follows Lex to Detroit and discovers he has found Kara, who has amnesia. However, Finley (guest star COREY SEVIER - "House of Fears," "North Shore"), a busboy who has become obsessed with Kara, fears Lex will take her away, so he shoots Lex and holds Kara and Lois captive. After finding Lex's comatose body, Chloe offers to heal him, but Clark refuses to let her.

Kara and Jimmy attend a ONE REPUBLIC concert, and it turns out that one of the roadies is former Smallville resident Pete Ross (SAM JONES III). Pete unwittingly chews some kryptonite-laced gum and develops superpowers. When Lex discovers Pete's powers, he threatens to reveal Chloe is a meteor freak if Pete doesn't help him break into Lionel's safe.

Lionel arranges to have Clark kidnapped and held in a kryptonite-lined cell at a LuthorCorp facility. After Chloe and Lana find a military electric probe at the farm, they confront Lionel, who throws suspicion onto Lex. Chloe and Lana take Kara to the Fortress and beg Jor-El to restore Kara's memory, as she is the only one who can save Clark.

Kara decides to teach Clark how to fly in order to strengthen his chances against Brainiac (JAMES MARSTERS), but Brainiac appears to have the upper hand against the super cousins. And some of Clark's loved ones are caught in the crossfire.

The secret of Veritas leads Lex in a dangerous direction that will put Clark and Lex in each other's crosshairs. There is a major power struggle, and one character dies.

Clark searches for Kara (LAURA VANDERVOORT) and Brainiac (JAMES MARSTERS) to reverse Lana's condition. Jimmy helps the Department of Domestic Security arrest Chloe.

Messages in the past indicate that Brainiac (JAMES MARSTERS) wants to kill baby Kal-El so Clark will not exist. Clark sees how life would be if he'd never come to Smallville.

A cloaked stranger who carves Kryptonian symbols into his chest -- a message for Clark -- attacks Lex. Chloe and Clark investigate and discover a member of Veritas has survived.

In an epic turn of events, Clark and Lex face off in the Fortress, and Lex learns Clark's secret.
