Twelve residents of a small Alabama town have mysteriously disappeared. When one of the missing is found dead, the VCTF begins an investigation. Once on scene, Sam is confounded by the evidence retrieved. Whereas some evidence points to a domineering, controlling pathology, other evidence points to a more passive, sub-servient one. 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.

A series of murders across the Southwest USA leads Sam and the VCTF team to an unlikely couple: a 32-year-old woman, Josie Wells, and a 16-year-old boy, Alex Lopez, who apparently abducted her from her child‘s soccer field in Boulder, Colorado. Sam figures out that the woman was apparently the victim of physical abuse as a child and has abandoned her unhappy and lonely married life and reliving her glory days with the boy she met on a counseling phone line. Meanwhile, Bailey tries to reason with his ex-wife, Janet, not to remarry for he feels she's throwing her own life away.

Years of verbal and physical abuse take a deadly toll when its victim lashes out against his abuser. Unable to kill the actual perpetrator, his mother, the deranged man strikes those who remind him of the wretched woman. The team investigates and Sam accurately assesses the killer's pathology, but mistakenly assumes the man is actin out against his wife, not his mother. When the ages of the victims begins to rise, Sam realizes her error and theorizes that the killer is slowly working up the courage to murder his tormentor. The team then races to find the ill-fated woman before her son can exact his final revenge. B-Story- Sam realizes she and Chloe must begin a new life, and to that end, decides to move into a new home.

A serial killer who kills with his bare hands leaves the bodies of his male victims at the Brown Derby, the Trocadero, and other Hollywood landmarks.

The team follows a trail of clues that eventually leads them to a rather ordinary cab driver who does not seem to have the strength necessary to commit the crimes. A search of the man's apartment yields evidence however, that matches Sam's profile to the letter. The cab driver easily passes a lie detector test. The conflicting findings lead to the release of the man. It is later learned that all the victims were abusers of women. Sam soon realizes the man suffers from multiple personality disorder. His alter ego is a gangster-like tough guy who is bent on avenging the murder of the cab driver's abused mother forty years earlier. B-Story- Sam learns her scientist father participated in experiments that had deadly consequences.

Meanwhile, Kevin Miller, an arrogant FBI agent working the case, complicates the investigation much to Bailey's worry for Sam's safety and Miller's indifference to otherwise, while John works with the local police detective, Lt. Cynthia Ford, in discovering the bodies.
