It appears that shrewd billionaire Lex Luthor has taken leave of his senses when he marries a woman he hardly knows. The new Mrs. Luthor is Smallville High School teacher Desiree Atkins, who has the ability to temporarily control a man’s mind by emitting a kind of pheromone mist. She and Lex wed shortly after they meet, and Desiree immediately sets out to steal the Luthor fortune by planning her transition from wife to widow. She tries to persuade Clark to murder her new hubby, but her powers don’t work on the Kryptonian so she’s forced to find another pawn. Meanwhile, Clark’s troubles aren’t over; he’s struggling with his latest gift—heat vision.
