The team investigates a serial rapist-turned-murderer in Illinois, whose sporadic timing of the attacks puzzles Sam as well as the connection between his victims whom are left in the woods. Sam figures out that the killer is an angry and frustrated married man taking out his rage and frustration on about-to-be-wed women. Meanwhile, with Jack-of-All-Trades (Donald Lucas) finally captured and imprisoned, Sam begins searching for a new house for her and Chloe.

A killer who castrates the victims seems to be driven by feelings of public duty and legal responsibility. John gets into trouble through no fault of his own for something that appears in the press about the case.

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.

The VCTF is called in to assist in a stalled investigation. Sam is leery to intercede, for her friend and former lover, Michael Westmore, is leading the investigation. The case revolves around a series of killings in which the victims have been burned alive. Once they begin their investigation, Sam and Bailey disagree about Michael's handling of the case. Whereas Sam feels her friend should be given some slack, Bailey feels the man's performance sub-par and should not be excused. Forensic evidence shows that the victims' eyes were the specific target to the killer. Sam uses her intuition and the evidence gathered to theorize the killer did not want to be seen by his victims. She later determines the man feels a great sense of shame, thus the reason he cannot bear to look someone eye to eye. Another victim is killed and Sam doubts whether the same killer is at work. It is later revealed that the copy cat killer is really Michael, using the same m.o. to cover up the murder of his mistres

Someone is George's hometown is stealing the corpses of young, recently decease Jewish woman. George fears it is some form of Anti-Semitic vandalism. As for to George, Bailey allows he and Sam to investigate the rather atypical crime further. Once on scene, George and Sam learn that a Neo-nazi group is alive and well in the town. Though evidence points to a member of the hate group, Sam feels the crimes are motivated by something other than Anti-Semitism. This theory take shape once two of the stolen bodies are found undamaged, with minor cosmetic changes made to their person. Sam put together a profile that characterizes the perpetrator as someone looking to create or re-create his vision of the perfect woman. Eventually, evidence points to a man who is insanely infatuated with a woman who works in his office. When the man kidnaps the object of his affection, Sam fears he will attempt to 'immortalize' his vision of perfect beauty for all eternity.

Fueled by the abuse they suffered as children, a brother and sister decide to save another child from the same unfortunate fate. To do this, however, the warped siblings kill the boy's parents as well as two of their employees. The VCTF investigate the mass murder and Sam immediately bonds with the abused boy. The parent has mob ties, so it is immediately assumed that their murder resulted from their illegal activities. Though skeptical of this scenario, Sam does not dispute it for that would result in the boy being held by the system until the murder is solved. Instead, the boy is immediately released to his uncle's custody. As the team investigates the crime further, they realize the boy's social worker, as well as his supposed 'uncle', are actually the brother-sister duo. Sam profiles the tow want to become surrogate parent for the boy and provide him with the idealized 'home' they never had. She further theorizes the boy must be found fast, before the disturbed couple realize paren

One of Sam's first profiles resulted in a man being sentenced to death. Ten years later when the man is about to be executed, murders begin happening that match the m.o. of the prior killings. Ballistics evidence proves the same gun was used for all the crimes. Sam, feeling culpable for what might have been a deadly mistake, reopens the investigation. Evidence leads to a lowly bicycle courier who is mortally wounded when he resists arrest. Once the dying man is in custody, the death row inmate is released from prison. Though a wrong seem to have been righted, Sam still feels something is amiss. A chess set is found in the prisoner's cell helps her to realize that the whole thing was an elaborate ruse. The man originally convicted was indeed the first killer. The second killer was only a pawn doing his bidding. Sam, Bailey, and the team re-arrest the now pardoned killer at the hospital bed of his wounded puppet, just as he attempts to kill the only loose end in his elaborate plan.
