Smallville Season 4

Clark Kent takes on a whole new dimension in this precursor to the Superman legend. You know how the story ends; now watch the journey begin. The idyllic town of Smallville, Kansas, never seemed the same after the meteor shower that rained down years ago. 

That was the day Clark Kent arrived on Earth - and the day strange things started happening in Smallville. Now, Clark is a teenager, and his growing pains are amplified by the burden of his emerging superpowers.

Episode guide

  1. 01 - Crusade

    Over a dozen years ago, a meteor shower burst from the heavens, raining destruction on the unsuspecting citizens of Smallville, Kansas. The intervening years have left the town's inhabitants with scars and secrets. From the ashes of tragedy, Clark Kent (series star TOM WELLING) has grown into a teen. The guardians of Clark's secret identity have always been his adoptive parents, Jonathan (series star JOHN SCHNEIDER) and Martha (series star ANNETTE O'TOOLE) Kent. The knowledge that his life is out of control has recently forced Clark to keep Lana Lang (series star KRISTIN KREUK), the girl he loves, at arm's length. Over the years, Clark has forged a remarkable relationship with Lex Luthor (series star MICHAEL ROSENBAUM), although neither has an inkling of how their destinies will ultimately collide.

    Clark returns from a bizarre phantom zone to Smallville, possessed by his Kryptonian alter ego, Kal-El. Intent on fulfilling his destiny, Kal-El takes to the skies to steal a powerful Kryptonite crystal. Meanwhile, Lois Lane (recurring guest star ERICA DURANCE - ""Tru Calling"") comes to town to investigate the murder of her cousin, Chloe (series star ALLISON MACK).
