In October 1989, a huge meteor shower destroyed most of the town of Smallville, Kansas, killed a lot of people, and brought Jonathan (John Schneider) and Martha Kent (Annette O'Toole) what they have always wanted, a son. In 2001, their son, Clark (Tom Welling), is a growing man, has two best friends, Pete (Sam Jones III) and Chloe (Allison Mack), and has a crush on the hottest girl in school, Lana Lang (Kristin Kreuk). But his parents have been hiding a secret from him: that they found him inside a spaceship when the meteor shower came. As he begins to develop his powers that will soon transform him into Superman, Clark begins to develop a friendship between his future arch-enemy, the bald Lex Luthor (Michael Rosenbaum), and fights the people that are transformed by the kryptonite that was hidden in the meteors, including a shape-shifting girl, a boy that is becoming more insect than man, and an old killer who can become young again.
