In the deep ocean of the judicial world, there are two special navigators. They are Bill Tench, who is over forty, and Holden Ford, a former field agent.Their voyage is unusual. They are not traveling on rough seas, but on the undercurrent of the human heart.Their job is to delve deep into the inner world of criminals and explore the logic and motivations hidden behind the madness.

Bill Tench, this experienced speaker, has traveled to police stations all over the world, and his voice echoes in every speech.What he talks about is the detection process of those thrilling classic cases, as well as the criminal patterns extracted from countless cases.His story is the crystallization of wisdom and courage, as well as the embodiment of in-depth research on criminal psychology.

Holden Ford, a former field agent, encountered insurmountable obstacles while handling a case and was transferred to the same job position as Bill.However, this transition became a new starting point for his career.He began to work side by side with Bill to explore the secrets hidden deep in the criminal's mind.

Both of them had a strong interest in studying criminal psychology. They persuaded their leaders to set up a behavioral science department in the basement with the idea that only by understanding the mind of a madman can they better catch the madman.This department is like a laboratory for their minds, where they talk to criminals and try to decode their behavioral patterns and psychological structures.

As their work progressed, their team attracted more like-minded people to join them, including psychology professor Wendy Carr.Her joining has injected new vitality into the team and provided more theoretical support for their research.

In their daily work, Holden and Bill will go deep into the prison and have conversations with various perverted murderers.They try to find out the true thoughts and motives hidden in the words of these criminals.These conversations are sometimes sincere, sometimes hypocritical, sometimes full of passion, and sometimes full of banter.But no matter what, they all learned valuable information from these conversations, which helped them establish a complete psychological model.

However, as their work deepened, they discovered that things were not as simple as they initially imagined.They begin to realize that the inner world of criminals is much more complex than they imagined.The behavior of criminals is often the result of a combination of factors, not just a single psychological motivation.

In the process, they also constantly refreshed their understanding of “abnormal”.They found that even those criminals who were considered “mad” often had certain logic and rules in their actions.These discoveries have strengthened their belief that only by deeply understanding the inner world of criminals can we better prevent and combat crime.

As their work continues to achieve breakthroughs, their team gradually receives more recognition and support.Their research results not only provide the police with more clues for detection, but also provide society with a deeper understanding of criminal psychology.

Episode 1

One morning after the rain in the late 1970s, the city woke up in the fresh air.However, beneath this peaceful surface, a thrilling kidnapping case is brewing.In this incident, a mentally ill kidnapper took hostages and all he asked was to speak to his wife.Faced with this difficult situation, the local police were helpless and invited FBI special agent Holden Ford.

With his rich experience and keen insight, Holden learned from the kidnapper's wife the real reason for the kidnapper's crime - he suffered from mental illness and had been off medication for a long time.However, when Holden tried to communicate with the kidnapper further, the kidnapper chose to commit suicide.This incident made Holden feel guilty, but his boss Shepard spoke highly of his performance and appointed him as a lecturer in the negotiation class of the FBI Teaching Department.

Despite the popularity of Holden's courses, he harbored an inner desire to delve deeper into criminal motivations.By chance, he overheard Les Rasman's criminal psychology course and became very interested in it.After the class, he had an in-depth exchange with Rasman, and both parties reached a consensus: Today's police have serious deficiencies in understanding the perpetrators' criminal motives.

Just as Holden was immersed in his exploration of the criminal mind, his career suffered a setback.His boss Sheppard rejected his request to study criminal psychology in depth and instead transferred him to the University of Virginia to work on police recruitment.Faced with this sudden change, Holden felt deeply disappointed.

However, fate is always full of twists and turns.When Holden was frustrated, he met Bill Tench from the Behavioral Science Department.Bill invited him to join his teaching tour team to teach FBI courses and exchange experiences.Holden readily agreed, and the two began a journey full of challenges and exploration.

Their first stop was an Iowa police station.Here, Holden and Bill try to teach the police that by analyzing the criminal behavior of the perpetrators, they can infer their experiences and psychological state.However, this view was not recognized by the police and instead attracted cynicism.Faced with doubts, Holden decided to teach using the case of serial killer Charles Manson.He believes that Charles's tragic childhood experience was a key factor that led him to become a murderer.However, this view was also opposed by the police.A senior police officer pointed out that Charles' criminal behavior was the reason why he was locked up, not his experience.

After the lecture, Holden and Bill unexpectedly met the senior police officer while dining in the restaurant.It turns out that the police are seeking their help, and a puzzling murder of a mother and son puts them in a new challenge.Although the two detectives had no clue about the case, they still decided to try their best to help the police solve the case.

In the process, Holden once again expressed to Bill his insistence on studying criminal motives.He believes that only by deeply understanding the psychology of the perpetrators can the police solve crimes more efficiently.However, Bill believed that this kind of research would lead people astray and rejected Holden's request.

Episode 2

In the deep ocean of psychology, every criminal's mind is a unique island waiting to be explored.When Holden and Bill came to Santa Cruz, California to continue their teaching and psychological research trip, they met a special “Island”-Ed Kemper.

Ed Kemper, a name that hides a shocking crime.As a teenager, he was imprisoned in a mental hospital for killing his grandparents; as an adult, he committed the crime of raping and murdering six young girls, and even poisoned his own mother, humiliating and killing her in extreme ways.she.However, this criminal, labeled as a "beast" by society, has become a rare research resource in Holden's eyes.

Holden's first meeting with Ed broke people's stereotypes of criminals.Ed is not vicious, he has a kind face and is approachable. During the communication with Holden, he even helped Holden get a sandwich for breakfast.With Ed like this, one can't help but think: What made him embark on such an extreme path?

In an in-depth conversation, Ed revealed his inner world to Holden.He believes that the reason why he became a murderer was not because of impulse, but because he had been humiliated and despised by his mother for a long time.Since he was a child, his mother used vulgar language to humiliate him and regarded him as a person who accomplished nothing.This long-term emotional torture made Ed finally burst out of his years of pent-up anger during a dispute with his mother as an adult, humiliating and killing his mother in an extreme way.

Ed’s story allows us to see the profound impact of family environment on children’s growth.A mother who humiliates her child from a young age may indeed make the child violent and despicable when he grows up.Ed believed that his crimes were entirely due to his mother's teachings and had nothing to do with him personally.Although this view is extreme, it also reminds us that the health of the family environment plays a vital role in the growth of children.

However, just as Holden and Bill delved into Ed's psychology, they encountered another difficult case.An elderly and kind grandmother was brutally beaten and her pet dog was killed.Judging from the crime, it was most likely the work of a local teenager who was drunk.Faced with such a case, Holden is even more convinced that studying the psychological characteristics of criminals can effectively help solve the case.

Therefore, Holden proposed to his superiors a series of plans to interrogate murderers, hoping to get support.However, the superiors were so annoyed by the two agents' private interrogation of Ed Campbell that they even wanted to punish them with demotions.After Bill's intervention, the superiors finally accepted Holden's plan, but asked for it to be kept secret and moved their offices to the basement.

Despite the difficulties they faced, Holden and Bill's determination did not waver.They know that there are complex psychological motives behind every criminal. Only by deeply understanding these motives can we better protect society and uphold justice.And Ed Campbell is an important chapter in their journey of exploring the psychological world.

Episode 3

In a quiet town, in-depth research on criminal psychology is closely linked to a serial murder case.This case attracted the attention of FBI agents Holden and Bill, who discovered that the victims were all elderly grandmothers with pet dogs.The psychological motives hidden behind the case confused the two people, so they decided to seek help from experts in the psychological field.

Dr. Wendy Carr, a renowned expert in the field of criminal psychology, was very interested in their research.She invited two agents to a university in Boston, Massachusetts, and shared with them the latest cutting-edge psychological research.Dr. Wendy suggested that recording conversations during interrogations and converting them into text would help the research progress.She also encouraged Holden and Bill to devote themselves to this research full-time and publish the research process or results to the world.However, Bill believed that the FBI would not approve of such a full-time research approach, so he politely rejected Wendy's suggestion and asked that the research be kept confidential.

Just as the two were planning the teaching tour route, an emergency phone call broke the calm.Police officer Roy Carver, who had handled similar cases, reported that another old woman was attacked and murdered for no reason.The escalation of the case made the two realize the seriousness of the problem.After obtaining permission from their boss, Sheppard, they quickly rushed to the Sacramento Police Department.

Through the investigation of the scene and the collection of clues, Holden overturned the previous conclusion that the suspect was a teenager.After discussion, they targeted Dwight, a man in his thirties who suffered from social disorders.In Dwight's residence, they found traces of a pet dog and a mother who was hostile and insulting to her son.During the interrogation, Dwight admitted his crime. Because he could not bear the insult from his mother, he chose to attack the innocent old woman.

Although the case was solved, the two detectives' research was not over.They wanted to interrogate new research subject Miller, but Miller refused to communicate.So, they turned their attention to Ed Campbell.Through the psychological offensive and the participation of Dr. Wendy, Ed gradually lowered his psychological defense.He admitted that everything he did was based on revenge for his mother's insult.Ed revealed that he buried the heads of six girls outside his mother's bedroom window, hoping to use their eyes to stare at his mother day and night.

After the interrogation, Bill admired Holden's eloquence and believed that they needed Dr. Wendy's expertise to analyze this complex case.After receiving the invitation, Dr. Wendy rushed to the FBI headquarters without hesitation to discuss the next research plan with the two agents.

Episode 4

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.

Episode 5

The triangular relationship between the central figures in the case, Benjamin, his sister Rose, and Frank has become the key to the case.

As Beverly's fiancé, Benjamin should have been the focus of the case investigation.However, he appeared extremely vulnerable when questioned by the police.When he mentioned his engagement to Beverly, he burst into tears and the police had to temporarily abandon their in-depth interrogation of him.This makes people question whether there is an unknown secret behind his performance?

At the same time, as Benjamin's sister, Rose's role in the case cannot be ignored.Although she initially appeared very calm in front of the police, as the investigation progressed, her inner conflicts gradually came to light.She confessed the details of being called to the scene on the night of the crime, as well as how she handled the blood stains and crime tools.However, she insists she does not know who the killer is, casting doubt on her true motives.

Frank's past was also unearthed by the police.His record in high school, where he was sent to a mental hospital for beating a teenage girl with a wrench, attracted police attention.Under police questioning, Frank faced his past frankly, but he insisted that he had changed his ways and no longer caused trouble.He also revealed that Benjamin and Beverly's engagement was actually just Benjamin's wishful thinking, as well as the disharmony in their sexual life.This information seems to point to Benjamin as a suspect in the case.

Episode 6

As the truth about Beverly's murder gradually emerged, the police finally captured the main suspects Benjamin and Frank.The investigation process of the case was full of hardships and twists and turns, but in the end justice defeated evil.

After torture, Frank and Benjamin revealed the truth of the case like squeezing toothpaste under unbearable pain.It turned out that on that fateful night, Benjamin tried to have a relationship with Beverly, but was rejected by her.Feeling rejected, Benjamin knocked Beverly unconscious and tied her up in anger.At this time, he was at a loss and could only turn to Frank.However, Frank took the opportunity to rape Beverly.Shockingly, Benjamin did not stop the rape from happening, but wanted to see Beverly humiliated.

Afterwards, both men realized they were in huge trouble.In order to get out of trouble, they actually decided to kill Beverly.When Ross, Beverly's sister, arrived to clean up the crime scene, she found Beverly still alive in the bathtub.An angry Benjamin stabbed Beverly several times, ended her life, and dumped her body in a garbage dump.However, a few days later, Benjamin still couldn't let go and went back to the garbage dump to humiliate Beverly's body and cut off her breasts for collection.

The truth finally came out, but sadly, the district attorney insisted on trying Benjamin first.Despite Holden's efforts to explain Frank's danger to the prosecutor, the prosecutor persisted in his position.In the end, Benjamin was found to be the main person responsible and faced a long prison sentence, while Frank was released after only a few years in prison.This result made Holden and Bill deeply dissatisfied. They believed that such a trial result did not truly reflect judicial fairness.

After the case was over, Bill invited Holden to his home for dinner.At the dinner table, Holden meets Bran, a child adopted by Bill from the orphanage.Blaine is very autistic, never smiling no matter what happens, and refuses to communicate with anyone, including Bill.This also affected Bill's relationship with his wife.

Meanwhile, Wendy returns to the university where she originally worked and starts dating gay people.During the conversation, she revealed that Holden's boss, Shepard, had sent her an invitation to join the FBI as a psychological research consultant.Although her lover expressed concerns about this and believed that she should stay in teaching at the university and spend more time with him, Wendy finally made up her mind to quit her job as a university professor and switch to a full-time consultant position with the FBI.

In many conversations with Ed Kemper, Rissel and others, Holden concluded that the root causes of crime are often related to family education in early childhood.He believes that all research will be meaningless if effective communication cannot be established with the people who really matter.In this context, Dr. Wendy recommended a special prisoner-Jerome Brudos to Holden and Bill.He is a transvestite murderer who likes to collect women's shoes.To gain insight into his psychological motivations and background, Holden and Bill immediately pack their bags and head to Oregon to visit this unique prisoner.

Episode 7

Detectives Bill and Holden arrive here, preparing to face a transvestite criminal - Jerome Brudos.His criminal history is shocking: from stealing women's underwear, to breaking into houses to steal skirts or shoes, to kidnapping and killing four women, every crime is heinous.

Jerome showed no usual remorse or fear when faced with interrogation.Instead, he insisted that all the crimes were framed and that he was an innocent bystander.He had his own explanation for his transvestism: he did not want to become a woman, but simply liked women's clothing.His childhood experiences also seem to be related to this: he picked up high heels when he was 5 years old, and stole the teacher's high heels in first grade. These experiences seemed to foreshadow his future behavior.

However, when Agent Holden tries to open Jerome's heart with a pair of high heels similar to his childhood experiences, things are not that simple.Jerome was so in love that he even picked up high heels and started masturbating, which undoubtedly caused great trouble to the detectives.Dr. Wendy was very dissatisfied with Holden's action. She believed that this approach was not in line with their research plan.

At the same time, the agents have their own concerns.Bill seemed powerless when facing his son's psychological problems.He handles all kinds of bizarre cases every day, interrogates all kinds of psychopathic criminals, and is already in a state of extreme stress.But Holden seemed absent-minded when facing the temptation of his girlfriend Debbie.Those high heels kept popping up in his mind, and he couldn't tear himself away from the situation of interrogating Jerome.

This story allows us to see the thoughts of transvestite criminals and detectives.The psychological world of Jerome Brudos is complex and contradictory. He has his own explanation and persistence for his transvestite habit.

Episode 8

Greg Smith, a special recruit, joins Holden's psychic research project team.Although Holden originally planned to hire an outstanding police sergeant, he had to accept Greg, whom he had never met, on the strong recommendation of his boss Shepard.

Soon, Roger Wade, a respected elementary school principal, came into Holden's sight.He invites Holden to the school to give a speech to children, aiming to guide children to identify and prevent bad behaviors.However, an unexpected discovery after the speech completely broke the peace of the school.An attentive teacher revealed to Holden that Principal Roger's behavior towards the children was somewhat inappropriate in private - he liked to tickle the children, especially those who made mistakes, and then give them pocket money.

This behavior caused an uproar among parents. Although someone reported the incident to the police, the police did not believe that it constituted a crime.Holden asked Bill to investigate the matter in depth together, but Bill believed that just because the principal liked to tickle students was not worth the trouble.So, Holden and Greg launched an investigation together.

Principal Roger argued that his behavior was just to help the children realize their mistakes in a relaxed way and did not have any sexual implications.However, as the investigation deepened, more voices began to call for protecting children and avoiding any behavior that was inconsistent with common sense.Although Greg emphasizes that Holden's opinions should be taken seriously as a member of the psychological research team, Principal Roger's tough attitude complicates matters.

Ultimately, the Virginia Education Association decided to fire Principal Roger and ban him from holding any teaching position nationwide.This decision caused widespread discussion in society, and many people began to reflect on how similar behaviors should be defined and dealt with.

At the same time, Holden's personal life also encountered twists and turns.He found that his girlfriend Debbie seemed to be drifting away from him, and instead she was getting closer to a new friend.At a party, Holden witnesses Debbie's intimate act with a strange man, which leaves him heartbroken.

Episode 9

The fax machine in the Atlanta office was clicking away as a new cold case file was quickly transferred to Holden's desk.This time, Lisa, a 12-year-old female student, became an innocent victim.She was excellent in both character and academics and was loved by her teachers and classmates. However, one day after school, she was raped and brutally murdered after getting off the school bus.A severe blow to the head, life evaporated in an instant, the case shocked the entire community.

Holden quickly invested in the investigation of the case.He carefully combed through the clues and found that the murderer did not have a careful plan, but committed the crime randomly.At the beginning, the murderer may have just wanted to commit rape, but things got out of hand during the process, which ultimately led to Lisa's death.During the exchange with local police officers, they identified Darryl, a tree plowing worker with a criminal record, as a suspect.However, according to procedure, they must complete a series of standard procedures before they can interrogate Daryl.

At the same time, Holden is also facing pressure from other quarters.The expelled Principal Roger was unable to engage in education-related work due to a ban. His wife found Holden and accused him of ruining Roger's life.She thinks Holden's behavior was reckless, but Holden insists he was just doing what he had to do.

In Illinois, Holden and his partner Bill prepare to interrogate a notorious murderer, Richard Speck.Richard is notorious for the drunken rape and murder of eight health school students.However, during the interrogation process, Richard became extremely resistant and swore at the two detectives.Faced with this situation, Holden decided to use unusual means and used insulting words to stimulate Richard to speak.While this approach eventually got Richard to talk, it also caused a strong dissatisfaction with Bill.

After the interrogation, Richard actually complained to Holden, claiming that he had been assaulted during the interrogation.The complaint attracted the attention of the Department of Compliance and Investigations, who requested a meeting with personnel from the psychological research program.To hide the fact that inappropriate language was used during the interrogation, Holden asked Gregg to erase the relevant portions when transcribing the documents.Although Greg lied to cover Holden during the investigation, his conscience finally drove him to send the original recording file to the investigation department.

Episode 10

In the Atlanta police station, a troublesome case was placed in front of senior detective Holden.Darryl, an seemingly ordinary man, was suspected of raping and killing a 12-year-old girl, Lisa.However, the thorny part of this case is that although the suspect has passed the polygraph test, the police could not find any strong evidence in Daryl's house and car.Faced with such a perfect criminal, Holden firmly believed in his intuition that Daryl was the murderer.

In the absence of sufficient evidence, Holden decided to use psychological tactics to break through Daryl's psychological defenses.He understands that interrogation is not just a battle with physical evidence, but also a battle with the suspect's mind.So, he started a “spiritual dialogue” with Daryl.

During the interrogation, Holden first tried to talk to Daryl about his past in a calm tone, trying to close the distance between the two.But Daryl seems to have long been accustomed to this trick of the police, and he is always vigilant to prevent himself from falling into any literal traps.Faced with Daryl's resistance, Holden was not discouraged. He knew that this was a protracted battle.

So Holden suddenly pretended that the recorder was malfunctioning and began to secretly pause the recording function.He plans to use a technique he learned during Richard's trial - speaking to the perpetrators in their own language.He began to use obscene terms to describe the victim Lisa, trying to make Daryl feel his “identity”“.Sure enough, Daryl was attracted by this ”resonance% and began to relax his vigilance.

Although other police officers resented this insult to the deceased, Holden believed it was necessary to solve the case.He believed that forcing out the truth would only be possible if Daryl was completely relaxed.Just when the atmosphere reached its climax, Holden suddenly and unintentionally revealed the stone that killed Lisa.Daryl's eyes were immediately attracted, and his psychological defense was unknowingly defeated.Finally, under the guidance of Holden and Bill, Daryl admitted his crime of killing Lisa.

The successful detection of the case made Holden famous and even appeared in newspapers.However, it also sparked a controversy over the interrogation method.Members of the psychological research team believe that this interrogation method may make criminals reluctant to talk to people from the psychological research team knowing that they will be used as a weapon to solve other cases.Greg then sent the original tape to the Investigation Department, which led to the Investigation Department learning that Holden had falsified the text during the interrogation, and the entire department got into trouble.

Faced with accusations from the Investigation Department, Holden insisted that his interrogation methods were effective.However, he also began to reflect on whether his actions were really correct.At the same time, the emergence of Ed Campbell put Holden into deep trouble.Ed wrote to Holden several times, hoping that the two could talk again, but Holden ignored his invitations every time.It wasn't until Ed attempted suicide and named Holden as his medical attorney that Holden had to visit him in the hospital.

In the hospital's intensive care unit, Ed is angry at Holden's indifference.He questions Holden if he really wants to be an expert on criminal psychology, suggesting that in order to study psychopathic criminals, he must first become a psychopath.Facing Ed's provocation, Holden felt a panic.He realized that he had become too obsessed with the conversation with crime and that the perverted murderer had affected his psychology.

In the process of escaping from the custody unit, Holden was on the verge of a mental breakdown.He realizes that he has been swallowed by the evil side and must re-examine his interrogation methods and attitude towards crime.This battle with desire makes Holden deeply realize that as a detective, he must not only pursue the truth, but also maintain his moral bottom line and mental health.Only in this way can he win in this never-ending contest.
