A desperate father kidnaps Sam's roommate Angel in a last ditch effort to save his son from the electric chair. The man's son has recently been convicted of murder committed during a robbery. The father believes his son to be an innocent bystander and wants Sam and the VCTF to prove it. To save Angel, Sam and the VCTF investigate the case and find little, at first, to prove the man correct. The father gives them the names of two potential suspects and Sam interrogates both. She also talks with the incarcerated son. Her discussions, along with forensic evidence, lead Sam to determine the son is in fact innocent of the murder, but is unfortunately an accomplice in the robbery. Once she knows the truth, Sam is faced with the difficult task of telling the father what he least wants to hear, that his son is indeed guilty of a crime.

Twelve residents of a small Alabama town have mysteriously disappeared. When one of the missing is found dead, the VCTF begins an investigation.

When Bailey pressures her to narrow her profile, Sam's anxiety builds and she begins to question her own abilities. Later, it is determined that there are two killers working together as a team- thus the reason for the conflicting profiles. One driven by the need for power and the other driven by his hero worship of his companion, the two have set out on a killing spree. Once the realization is made that there are two killers, Sam is greatly relieved to find out that her intuitive skills are still intact.
