First look: 'Law & Order: SVU's' 300th episode Will Hart / NBC From left, Ice-T, Danny Pino, Kelli Giddish, Dann Florek, executive producer Dick Wolf, Richard Belzer and Mariska Hargitay celebrate "SVU's" 300th episode. "Law & Order: Special Victims Unit" kicked off on Sept. 20, 1999, and 13 years later, NBC's hit procedural drama is set to air its landmark 300th episode on Wednesday. Granted, the show no longer stars the beloved (and dearly missed) Christopher Meloni as Det. Elliot Stabler, but it chugs on with Mariska Hargitay's Det. Olivia Benson, Dann Florek's Capt. Cragen, Ice-T's Det. Fin Tutuola, Richard Belzer's Sgt. John Munch and newcomers Danny Pino as Det. Nick Amaro and Kelli Giddish as Det. Amanda Rollins. Though other faces have also come and gone from the squad, the crimes they investigate remain horrible ... and sometimes reminds the SVU of its old cases. In episode 300, titled "Manhattan Vigil," when a little boy named Wyatt disappears, Cragen, Munch and Benson are reminded of a similar kidnapping case in the same neighborhood that went cold 13 years ago. The new disappearance leads the squad to race against time to find the child. Check out our exclusive first look as Rollins and Fin try to find a lead in the boy's disappearance: Want more before the episode airs?
