Recently, a shocking murder of a nanny occurred in Virginia, which attracted the attention of FBI agents Holden and Bill.They discovered that the case was subtly connected to a recently convicted serial killer, Monte Rissell.

Riesel was convicted of raping and murdering five women. His criminal history was full of violence and cruelty.During the interrogation, although Riesel initially refused to communicate with the detectives, he gradually opened his heart under the inducement of a bottle of his favorite drink.He revealed his childhood misfortunes, including his mother's remarriage, his stepfather's abuse, and the depravity of his older brothers and sisters, all of which made him deeply aware of the injustice of life.He believes that if he could have lived with his biological father, his life might have been different.

Holden's psychological research team analyzed that Risel's criminal motives stemmed from the desire for control and his girlfriend's cheating.During the crime, he mistakenly believed that the girl enjoyed this kind of behavior, which resulted in a twisted mentality of killing people to pleasure himself.This psychological change, like a domino, triggered his subsequent series of murders.

While investigating Rissell, Holden and Bill also faced a difficult case-the mysterious death of nanny Beverly Jane.Her body was abandoned in a garbage dump with multiple injuries, especially the removal of her breasts and deep incisions from her genitals to her anus, which revealed the murderer's abnormal color.Based on clues, Holden deduced that Beverly might have been killed by an out-of-towner while working as a nanny.However, during the investigation, although some suspects surfaced, there was insufficient evidence and the case was deadlocked.

During the investigation, the addition of local police officer Mark brought a new turn to the case.He heard about Holden and Bill's ability to handle cases and hoped that they could help solve this case.However, faced with complex cases and cunning murderers, the three-person team also felt under pressure.

Fortunately, with the support of the FBI, their psychological research project has received the attention and financial support of multiple law enforcement agencies.This gives them the opportunity to expand their team and recruit additional talent to assist with investigations.
