The police teams from "Law & Order" and "Law & Order: Special Victims Unit" probe the gunshot murder of a man believed to be a sexual aggressor but the evidence points to the trouble-prone daughter (guest star Noelle Beck) of a wealthy family whose protective and haughty female clan leader (Emmy and Tony Award winner Jane Alexander) could make trouble for investigators and prosecutors alike. But when another duplicate murder occurs, the cops re-think their primary suspect while Detective Briscoe (Jerry Orbach) believes they might have stumbled upon new evidence about a serial killer who eluded him five years earlier. Mariska Hargitay, Christopher Meloni, Dann Florek, Richard Belzer, Michelle Hurd, Jesse L. Martin, Sam Waterston and Steven Hill also star.

A young Romanian girl, Alexis Campbell, who was adopted by an American family, lies near death after two cups of detergent are pumped from her stomach. Her seemingly normal family is upset, but her six-year-old sister Katie (Sloane Momsen) claims her mother tortured Alexis. Even though the family wanted to adopt Alexis, her mother, Karen (Cynthia Gibb), got pregnant with twins shortly after. A.D.A. Novak (Diane Neal) wants to prosecute Karen for murder, but Oliver Gates (Barry Bostwick), her defense attorney, doesn't want to allow Katie's testimony. Judge Oliver Taft (Tom Skerritt) makes it very difficult for Novak and agrees Katie should not be allowed to testify, but does agree to a bench trial. Stabler (Christopher Meloni) testifies and rips Judge Taft apart and "mouths off" on his way out. Judge Taft retaliates quickly, tossing Stabler in jail for contempt. Judge Taft finds Karen not guilty and Novak is furious, and wants Taft off the bench. Mary Conway Clark (Marlo Thomas) advises Novak to be careful, but Novak is determined to proceed.
