Newly aware that his superpowers include "heat vision," Clark (
Tom Welling) finds that this talent may be a detriment when he crosses paths with new Smallville High School teacher Desiree Atkins (
Krista Allen). After a whirlwind two-week courtship, Lex Luthor (
Michael Rosenbaum) feels compelled to marry Desiree, little suspecting that she is controlling his mind with an invisible, kryptonite-based pheromone mist. When Clark becomes suspicious of Desiree's motives, she promptly frames him for starting a fire -- then sets about to simultaneously destroy both Clark's adoptive father, Jonathan (
John Schneider), and her wealthy new hubby, Lex. ~ Hal Erickson, All Movie Guide
