After a young woman has been raped and murdered, her body turns up in an industrial laundry facility. Detectives Benson (Mariska Hargitay) and Stabler (Christopher Meloni) soon find that she was involved in an environmental group called CLEAN, and it isn’t long before they track down the prime suspect. However, the case soon puts them in the line of fire and exposes a much larger mystery that includes even more victims. As the investigation progresses, Detective Benson builds a connection to a victim’s daughter (guest star Maria Bello) that invokes her own past in ways she never anticipated. Alex Kingston guest stars. Also starring: Richard Belzer, BD Wong, Tamara Tunie and Dann Florek.

FBI Agent Dana Lewis (guest star Marcia Gay Harden) is assaulted by a stranger and asks Detective Benson (Mariska Hargitay) to have her rape kit tested. Before the cops can really help her, Lewis goes back undercover and refuses to talk about the assignment or the rape, for fear that she will be exposed and pulled off the case. She reluctantly allows Benson and Stabler to get involved in what looks like a protest against the construction of a mosque at Ground Zero, but they find themselves scrambling to put the pieces together of a much larger puzzle than they had anticipated. Also starring: Richard Belzer, Ice-T, Dann Florek, BD Wong, Tamara Tunie and Melissa Sagemiller.
