This anthology show features a different cast of characters and storyline for each season. The series begins in 2012 and follows two former Louisiana State Police Detectives as they are brought in to revisit a homicide case they worked on in 1995. As the inquiry unfolds in present day through separate interrogations, the two former detectives narrate the story of their investigation, reopening unhealed wounds, and drawing into question their supposed solving of a bizarre ritualistic murder in 1995. The timelines braid and converge in 2012 as each man is pulled back into a world they believed they'd left behind. In learning about each other and their killer, it becomes clear that darkness lives on both sides of the law. Rust Cohle (Matthew McConaughey) transferred out of Texas law enforcement. A cerebral, intense thinker, he holds a negative view of society which sometimes puts him at odds with his partner and the rest of the force. Rust's partner is Martin Hart (Woody Harrelson) and the more conservative of the pair. While he may not always understand Rust's methods, he respects his partner's commitment to police work and runs interference between Rust and their commanding officer. Marty has two daughters with his wife, Maggie (Michelle Monaghan), a nurse at the local hospital. Intelligent and outspoken, her instincts are as sharp as her husband's. They met in college. Major Ken Quesada (Kevin Dunn) was the detectives' the supervising officer in 1995. Detective Maynard Gilbough (Michael Potts) and Detective Thomas Papania (Tory Kittles) are the investigators probing Hart and Cohle for answers in the present.
