S13, E22: While off-duty, Detective Rollins (Kelli Giddish) spots a young woman screaming in the back of a moving taxi. The SVU squad quickly identifies the victim as a rebellious teenager, estranged from her family and experimenting in the world of tattoos and self-mutilation. The case takes an unexpected turn when the Medical Examiner (Tamara Tunie) presents the detectives with a cleanly severed leg, reminiscent of a similar finding in an old unsolved case. The detectives are drawn into the psychological elements of self-mutilation and ritual amputation as they investigate two brothers (guest stars David Eigenberg and Patrick Fischler) in order to link the cases and find the missing woman. Also starring Mariska Hargitay (Detective Olivia Benson), Ice-T (Detective Odafin Tutuola), Dann Florek (Captain Donald Cragen) and Danny Pino (Detective Nick Amaro).
