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.
