Overweight teen Jodi submits to a diet of meteor-infected vegetables from her father's greenhouse. They magically make her thin, but she has an intense craving for body fat. Anyone in her vicinity is in danger, including her date, Pete.

After stealing an experimental flower laced with meteor-rock pollen from Dr. Steven Hamilton, the employee of the Luthor Corp, James Beales has a truck accident on the road and is rescued by Jonathan Kent. However, the flower releases its pollen on Jonathan's face, and he unleashes his innermost repressed desires first with Martha and his anger towards the Luthors. He enters in coma later. Then Lana becomes affected and tries to seduce Clark. Pete also becomes affected by the Nicodemus flower in the same way. While Clark helps Lex track down the source, Lex hides from Clark that Dr. Steven Hamilton is working for him, but they find the cure in an old book.

Lana develops a form of clairvoyance after being injured by an explosion, and she has visions of the activity of a local serial kidnapper and killer. When Chloe is kidnapped, Clark must rely on clues from Lana's visions to save her.

When Dr. Steven Hamilton, physically sick from repeated exposure to meteor rock radiation, causing constant Parkinson-like twitches, becomes a liability to Lex Luthor, he terminates their contract. Dr. Hamilton leaves the mansion and drives down the road like a lunatic and causes a serious accident with a truck driven by Ray Wallace. The truck overturns in a cornfield near Clark Kent's spacecraft and, while trying to rescue Ray, Pete Ross sees the UFO. The next morning, Pete asks Clark to help him to bring the object to his workshop. When Dr. Hamilton steals the spacecraft, Pete believes Clark has taken it, so Clark discloses his secret to his friend. Meanwhile, the now blind Lionel Luthor moves into Lex's mansion forcing Lex to care for him. Also, to Lana's dismay, her aunt Nell Potter is in love with a new boyfriend named Dean.
