A string of rapes in West Soho inspires a group of vigilantes to organize against both neighborhood crime and the NYPD. While Reporter Dennis Griscomb (guest star Gavin Lee) takes every opportunity to publicly criticize police efforts, the SVU squad struggles to find a lead in the case until one of the vigilantes is attacked. As the other detectives fight for control over the investigation and angry citizens, Amaro (Danny Pino) is distracted by the suspicion that his wife (guest star Laura Benanti) is seeing another man (guest star Dominic Fumusa.)
Detectives Benson (Mariska Hargitay) and Amaro (Danny Pino) investigate the disappearance of a teenaged girl after her young brother calls 9-1-1. While Fin (Ice-T) and Rollins (Kelli Giddish) look into a possible abduction, they discover the girl had been searching for her biological father, an anonymous sperm donor. The investigation takes a startling turn when a suspect is found to be targeting several young, vulnerable women, all with the same personal connection. But the suspect isn’t what he seems, and Dr. Huang (Wong) must delve into his past to save the women.
