Surrender Benson / Imprisoned Lives

S15 E1: Hours turn into days, and with no word from Detective Benson (Mariska Hargitay), the SVU squad takes drastic measures to find her and her abductor (Schreiber). A trail of murders and rape victims leads them to fear it may be too late. An abandoned child leads the svu to a dangerous kidnapper and more victims. A young boy is abandoned in Times Square and leads the detectives to the house where his family lives. Inside they find a locked basement where more victims await rescue, and work to solve decades-old cold cases.
