Mulder faces his feelings about the disappearance of his sister after a girl in Iowa mysteriously vanishes.

Mulder and his new partner, Alex Krycek, face a sleep-deprived marine who may possess the ability to kill with his dreams.

Mulder and Scully investigate a man whose wounds reportedly resulted from suicide attempts but seem to suggest something sinister.

When Chloe accidentally inhales a mysterious gas, she discovers that it gives her the ability to get the truth from anyone who comes in contact with her--and she goes to the Kents to find out Clark's secret. However, her new power is not without its consequences, and Clark must find an antidote before she discovers too much about him or, worse, dies.

As a massive tornado approaches the unsuspecting Smallville, Clark finds a missing piece of the spaceship that carried him to Earth. The part activates the disabled craft, giving Clark the first clue as to where he came from. Meanwhile, Lex experiences two disturbing events: His father, Lionel (recurring guest star JOHN GLOVER), closes the plant and orders Lex to return to Metropolis, and the deceitful reporter Lex hired to spy on the Kents discovers Clark's superhuman abilities and the spaceship hidden in the storm cellar. Members of the rock band Remy Zero (themselves) perform their hit single "Save Me"--the "Smallville" theme song--at the Smallville High School formal dance.
