Twelve years ago, Jack worked a serial killer case in which five women were murdered, and he was unable to prevent the carnage. Now, Jack and the team search for a missing woman whose description is remarkably similar to the five murder victims from long ago. The man guilty of the original crimes, Randy Thorton (Keith Brunsman), remains in jail, but the team learns that Graham Spaulding (Conor O'Farrell), a pedophile Jack arrested in a previous case, visited Thorton. Jack soon realizes that Spaulding is imitating the original case in an effort to exact revenge on Jack and that Spaulding has uncovered information about Jack's own family. Tim Matheson ("The West Wing") directed the episode.
