Clark reels from his first flashes of X-ray vision. His shock is compounded when he witnesses a bank robbery, apparently by his friend, Lex. Unsure of how to control this new power, Clark nonetheless puts it to use when a Smallville teen who has developed shape-shifting abilities threatens Lana.
Clark is wracked with haunting visions when he meets an old woman, Cassandra Carpenter (JACKIE BURROUGHS), who can see the future. Lex schemes to use Cassandra's gift to glimpse his own destiny and learn more about Clark's secret. Meanwhile, a bitter old man, Harry Bollston (GEORGE MURDOCK), discovers a "fountain of youth" and reverts to a teenager. He then seeks revenge on the descendants of jurors who put him in jail decades ago.
Clark and Lex team up to rescue members of Clark's high school class after a janitor, Earl Jenkins (TONY TODD), takes them hostage in LuthorCorp's Smallville Fertilizer Plant No. 3. Jenkins claims his deadly "jitters" were caused by a mysterious contaminant, and he threatens to kill everyone unless he is shown a secret sublevel--which Lionel Luthor (recurring guest star JOHN GLOVER) denies ever existed.
Clark's secret identity is jeopardized when a corrupt policeman, Sam Phelan (CAMERON DYE), witnesses Clark using his superhuman powers and coerces him into joining forces.

Meanwhile, Lex receives an intriguing proposal from his sexy British ex-girlfriend, Victoria Hardwick (recurring guest star KELLY BROOK - "The Big Breakfast").
A wild storm buries alive Clark's father and a reporter (Tom O'Brien) who has uncovered Clark's secret.
