Briscoe and Green investigate the murder of two teenage girls, one of whom is found wrapped in plastic sheeting in a house under renovation. The victim was raped and strangled and had a high level of the drug GHB in her system. When the detectives learn that one victim's sister, Laura Kendrick, is also in New York, they begin a frantic search for her, eventually finding her in a hospital, beaten and drugged. She points the finger at her boyfriend, Peter Williams, who may also be responsible for other brutal rapes and murders. The detectives begin to suspect that Laura Kendrick also may have participated in the assaults, but she claims Williams forced her to participate. To get a conviction, Jack McCoy agrees to a plea bargain with Laura Kendrick for a minimal sentence in return for her testimony, but he later learns that he may have made a deal with the devil.
