Detectives Jack and Paco investigate a murder spree on the rock ’n’ roll, cocaine-infused revelry of the Sunset Strip.
Detectives Jack Roth (Jeremy Sisto) and new partner Paco Contreras (Gabriel Luna) are assigned to track down a killer who preys on women seeking fame in the City of Angels. Their perp, unbeknownst to them, is Kent Grainger (Ed Westwick), a tragic soul who craves attention and goes on a murderous rampage to obtain notoriety. Jack and Paco get a break when they stumble upon Karen McClaren (Taissa Farmiga), a young, struggling journalist who may have met the killer at a club and could I.D. him – but she may also be his next target. Meanwhile, Kent has found himself a young woman who may be his ‘Bonnie' to his twisted ‘Clyde' in the form of Betty Beaumontaine (Erika Christensen), a nurse and single mother of two with a bit of a sadistic twist.
Jack and Paco get a lead on the serial killer's next possible victim and race against the clock to try and track her down before the killer gets to her; Kent struggles over whether or not to invite Betty to take part in his murderous rampage when it becomes clear that she doesn't trust him and may leave him, and Jack and Paco continue to search for Karen, who has disappeared from the club,
Betty struggles with the revelation that Kent is a serial killer when he gives her a copy of the novel "Phantom of the Opera" and asks her if she can love him the way Christine loved the Phantom. Meanwhile, Jack and Paco trace the ownership of the lair and identify the body they found in the floorboards as Vera Bennett, a former librarian. During the investigation at the library where Vera used to work, they run into Karen and Diver, who confess about a letter Kent sent them. Hoping to get additional clues, they are shocked when they uncover a huge surprise on a bookshelf. Later, Dianne points out Jack, and the killer might not be so different after all.
Jack focuses on a woman from the past who may have been the catalyst for the murderer's current killing spree; Betty decides to go all-in as Kent's partner, and together they troll a club in search of a victim; Karen is offered a job with Rolling Stone, which does not please Diver; a menacing old flame of Betty's reemerges and sets his sights on trying to reignite their troubled past; and Dianne finds herself in dire straits when her allegiances are questioned by a powerful drug lord.
Betty finally introduces Kent to her kids.
Jack and Paco unleash a full-scale manhunt for Kent.
