M6, T6: A young boy, Henry Morton (Max Iles), disappears from a child's birthday party. His mother is horrified and there is a "pull out all the stops" search for his abductor. They are determined to find this boy alive. The detectives initiate a massive search, but are disrupted by Malcolm Wolinsky (Bruce Kirkpatrick), an advocate against child molesters who often takes the law in his own hands. Captain Cragen (Dann Florek) warns him to leave the case alone, and threatens to charge him with obstruction if he interrupts again. Detective Benson (Mariska Hargitay) and Stabler (Christopher Meloni) are questioning Henry's parents when Jake O'Hara (Jordan Garrett), the Morton's 13-year-old neighbor, claims a man in a dark car was following Henry. The trail leads to convicted child molester Billy Turner (P.J. Brown) and Wolinsky is right there when he's picked up.
