S5, E1: More than 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 an awkward teen. While adolescence always brings its challenges, Clark's transition from boyhood to manhood has been particularly difficult. He has struggled to come to grips with his emerging superpowers--and the effects of various forms of kryptonite--while battling the strange things that have plagued this idyllic Midwest hamlet since the meteor shower. The guardians of Clark's secret identity have always been his adoptive parents, Jonathan (series star JOHN SCHNEIDER) and Martha Kent--although Clark's friend Chloe Sullivan recently learned of Clark's powers.
