Stranger

S10 E11: Heather Hallander (guest star Ellen Woglom) miraculously returns home after being reported missing over four years ago. Unrecognizable to her family, Heather tells Detectives Olivia Benson (Mariska Hargitay) and Elliot Stabler (Christopher Meloni) of the cement cell where she spent the past four years as a sex slave and of her fortunate escape. Heather’s sister, Erica Hallander (Kate Baldwin), is relieved to see her long-lost sister after launching a website asking for search tips, but, Nikki Hallander (Natalia Payne), Heather’s other sister, seems annoyed with her return. In search of the mystery kidnapper, Benson and Stabler drive Heather around town to help stir up any memories of her abduction. When Heather’s answers don’t seem to match up, the detectives find revealing evidence that make them question Heather’s kidnapping and true identity. Also starring Dann Florek, Richard Belzer, Ice-T, Michaela McManus, B.D. Wong, and Tamara Tunie.
