Jo Marlowe, Stabler's old partner before SVU, becomes the new ADA for the SVU team and enlists the help of Benson and Stabler in the case of two young girls, presumably left to die in a burning house by their father (Kevin Anderson). Upon further investigation by the SVU squad, however, it is discovered that the father did not set the fire that consumed his two daughters, later exposing the incorrect assumptions of a fire marshal (P.J. Benjamin) with the help of an independent pyrotechnic investigator (Brad Dourif).
Detectives Benson and Stabler must track down a pregnant rape victim (Hanna-Liina Võsa) who disappears from the hospital. In the process, they uncover a vast baby-trafficking scam, led by a Bulgarian crime lord (Pasha D. Lychnikoff). When the woman (Gordana Rashovich) who housed the pregnant mothers is discovered murdered, Benson and Stabler go undercover as infertile parents, while ADA Marlowe clashes with Cragen over methods to protect the kidnapped woman and her newborn child. Matters become complicated in the trial when the gynecologist (David Paymer) involved is assigned the same lawyer as the mob that used him for his access to pregnant women. He realizes that if he testifies truthfully he will be killed so a shadow counsel is arranged.
