HBO's making of True Detective, a crime drama centered around two Louisiana State PD detectives, and their 17-year hunt for a ritual killer, starring Matthew McConaughey and Woody Harrelson.

Former Louisiana State CID partners Martin Hart and Rustin Cohle give separate statements to a pair of investigators about the murder of a prostitute, Dora Lange, 17 years earlier. As they look back, details of the crime, replete with occult overtones, are accompanied by insights into the detectives’ volatile partnership and personal lives.

Under pressure to land a suspect in the Lange murder, Quesada warns Hart and Cohle that they might be replaced by three detectives from a new task force. The pair lobbies for extra time to follow up on a lead that takes them from a rural cathouse to an incinerated church. With his marriage to Maggie already strained by work, Hart finds respite away from home.

A hidden image at the burned-out church leads Cohle and Hart to Joel Theriot, a tent-revival minister whose parishioners finger a scarred “tall man” seen with Dora Lange. Brought in for interrogation, a sex offender matching the description is quickly dismissed by Cohle, despite offering a confession. Hart gets sidetracked after Maggie sets Cohle up with a friend at a C&W bar. Looking to establish a pattern of murder, Cohle pores over old case files, finding a connection with a woman assumed to have drowned years earlier.

Hart and Cohle hunt for their newly identified suspect, Reggie Ledoux, a meth cooker who shared a cell with Dora Lange's husband and recently skipped parole. As Hart's personal life collapses around him, Cohle immerses himself in an old criminal identity from his narco days, contacting an East-Texas biker gang known to deal with their primary suspect.

A violent denouement in the forest clears the Dora Lange case and turns Cohle and Hart into local heroes. Each man settles into a healthier rhythm of living as Hart returns to his family, and Cohle starts a relationship while gaining a reputation as a closer in interrogations. As time passes and his daughters grow older, Hart faces new tensions and temptations, and Cohle learns from a double-murder suspect that there could be much more to an old case than he'd once thought. In 2012, Gilbough and Papania put their cards on the table, presenting new intelligence that threatens Cohle and causes Hart to reassess everything he thought he knew about his former partner.

Maggie reveals Cohle's activities in 2002, when his relationship with Hart fractured and he quit the force.

Hart and Cohle call a truce to investigate a series of disappearances that may be related to the Dora Lange murder and the Tuttle family.

An overlooked detail provides Hart and Cohle with an important new lead in their 17-year-old case.

The disappearance of a young Arkansas boy and his sister in 1980 triggers vivid memories and enduring questions for retired detective Wayne Hays, who worked the case 35 years before with partner Roland West. What started as a routine case becomes a long journey to dissect and make sense of the crime.

Hays looks back at the aftermath of the 1980 Purcell case in West Finger, Arkansas, including possible evidence left behind at the Devil's Den. As attention focuses on two conspicuous suspects--Brett Woodard, a solitary vet and trash collector, and Ted LaGrange, an ex-con with a penchant for children--the parents of the missing kids, Tom and Lucy Purcell, receive a cryptic note.

Hays recalls his early romance with Amelia, as well as cracks in their relationship that surfaced after they married and had children. Ten years after the Purcell crimes, new evidence emerges, giving him a second chance to vindicate himself and the investigation.

Hays and West see a possible connection between the local church and the Purcell crimes. As the detectives search for one suspect and round up another for interrogation, Woodard is targeted by a vigilante group.

Wayne finds himself in a no-win situation as new clues emerge in the Purcell case. Roland wrestles with how to keep evidence secure as lawyers demand a new investigation. Amelia finds her relationship with Wayne imperiled by her writing aspirations and his jealousy.

Wayne and Roland revisit discrepancies in the Purcell case that were hidden or forgotten over the years. Among those being reevaluated is Tom Purcell, as well as Lucy Purcell’s cousin, Dan O’Brien. The glitter of Amelia’s book release is tarnished by a voice from the past.

Following up on new leads, Wayne and Roland track down a man who left the police force in the midst of the Purcell investigation. Meanwhile, Amelia visits Lucy Purcell’s best friend in hopes of gaining insights into the whereabouts of the mysterious one-eyed man.

Wayne struggles to hold on to his memories, and his grip on reality, as the truth behind the Purcell case is finally revealed.
