In M. Night Shyamalan's latest outing, everyone in a large city is in a frenzy. Why? That's because they're up and ready to watch a concert performed by famous pop star Lady Raven. Two of her fans, a man named Cooper and his daughter Riley, attend the concert with high spirits, but things slowly begin to change their tune. Amongst the screams of adoration and sounds of applause, the concert itself has a hidden identity: a front to fish out an infamous serial killer known as The Butcher. With security cameras rigged, armies of policemen with weapons at the ready, and police vehicles surrounding the venue, will anyone survive their concert experience or is there more to The Butcher than meets the eye?
In 2012, Louisiana State Police Detectives Rust Cohle and Martin Hart are brought in to revisit a homicide case they worked 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.
