Pediatrician Gilbert Keppler is found guilty of sexually assaulting four of his male patients. Soon after his trial, his attorney Lionel Granger informs the detectives that Keppler will be suing the NYPD and the Denslow Medical Center on the grounds that they knew he was sexually abusing patients long before they took any action to stop him. Detectives Elliot Stabler and Olivia Benson decide to go directly to Keppler for questioning only to find him murdered in his apartment. To the detectives' surprise, ADA Alexandra Cabot shows up at the crime scene, after three years in the witness protection program. Attorney Lorna Scarry reminds Cabot how tough solving a case can be. The SVU team must put the past and lost time behind them in order to solve the case.
