Smallville tells the tale of a teenage Clark Kent in the days before he was Superman. It is the town where he came from where very strange things started happening with his arrival in a spaceship in the midst of a meteor storm of green rocks.
Clark must deal with a variety of individuals given powers by the green rocks, keep his powers a secret, cope with his friendship with a young Lex Luthor, and balance the two girls in his life, Chloe and Lana. The show also shows us how Lex Luthor develops from a friend of Clark's and kinda-okay guy to (presumably) the villain who will plague Superman in his later years.
