Returning for a fourth season of adventures in SMALLVILLE, the young Clark Kent (Tom Welling) once again attempts to balance his high school life with the superpowers he was equipped with at birth. The season begins with Lois Lane (Erica Durance) turning up in Smallville to investigate the death of her cousin. In a neat touch, Margot Kidder, who plays Lois in the Christopher Reeve-era SUPERMAN movies, makes an appearance in the first episode. Meanwhile, Lana (Kristin Kreuk) has picked up a new boyfriend in Paris, Lex (Michael Rosenbaum) has got his hands on a kryptonian crystal in Egypt, and Lionel (John Glover) sets a mutant on the trail of Chloe (Allison Mack) to determine whether she is dead or not. A wonderful counterpart to the adult adventures of SUPERMAN, SMALLVILLE continues to go from strength to strength.
