Having served 40 years in prison for the murder of his wife, Louise, in 1961, Lana Lang's great uncle Dex (Tom Heaton) shows Lana (Kristin Kreuk) a photo of the man who may have actually committed the crime. The person in the picture looks exactly like Clark Kent (Tom Welling) -- leading Clark to conclude that his Kryptonian birth father, Jor-El, may have visited the earth four decades earlier. With the help of a Krypton medallion, Clark is able to straddle the years in an effort to solve the mystery -- which also involves Smallville mayor William Tate (William B. Davis).
