After leaving an article full of denunciations about the "Summerholt Neurological Institute" with her former colleague of the Daily Planet, Max Taylor, Chloe is chased by Clark Kent who tries to run her down with his truck. He claims that he had received an e-mail just before his action. Later, Lana also receives an e-mail from the same address and tries to kill Chloe on the steps of Smallville High, who is saved by Adam Knight. Clark and Chloe, with a little help from Lex, investigate the mysterious e-mail origin, and they discover that Molly Griggs, a former patient of the unethical Dr. Garner, is using her meteor-rock abilities to force people to kill through a hypnotic suggestion in her e-mails. Meanwhile, Adam moves to Smallville to be close to Lana despite that nobody knows anything about him. Also, Lex makes contact with Dr. Garner and threatens to expose his unethical practices unless he helps him regain his memory of the last seven weeks.
