Jitters

Plot:

Former Luthor Corp employee Earl Jenkins, and who also worked at the Kent farm, has an unknown disease that violently shakes all his body. He arrives at the Kent farm during a party Clark throws while his parents are out of town and claims that the disease developed following an explosion at his former workplace: Level 3 of Luthor's Smallville plant which was experimenting with meteor-rock laced fertilizer. Trouble is, there is no Level 3! Determined to prove his case, Earl breaks into the plant and takes a class touring the plant hostage. Lex arrives with the police and trades himself for the hostages, while Clark stays behind to try to help Lex and find out more about 'Level 3' which Lex claims to know nothing about. But Lionel apparently knows about the mysterious secret underground level when he arrives with his personal goon army determined to keep the secret experiment under wraps... at the expense of anyone, even his own son Lex.
