Clark (Tom Welling) and Lana (Kristin Kreuk) discover an abandoned baby in the cornfield and take him back to the Kent farm. However, once the baby ages from a newborn to a 7-year-old in a matter of days, the two realize he is aging at a rapid rate and frantically search for a cure before the disease kills him. Meanwhile, Genevieve (guest star Jane Seymour) orders Lionel (John Glover) to kill Lana or else she will send him back to prison.
