Pablo Schreiber and Mariska Hargitay

Law & Order: SVU's Season 15 premiere (on Sept. 25) opens a few hours after last season's cliff-hanger, in which Det. Olivia Benson (Mariska Hargitay) was seized by the ­vicious rapist-killer known as the Beast (Pablo Schreiber). And he's living up to his reputation.

"This is one of the more disturbing bad guys we've ever had on SVU," says executive producer Warren Leight. "As a result of what happens to her, this year will be different for Olivia."
