In the episode, Rollins (Kelli Giddish) witnesses an abduction that leads her and the elite squad of detectives known was the Special Victims Unit into the world of self-mutilation and fetishes.
Tamara Tunie returns as medical examiner Warner and presents the detectives with a severed leg, one that harkens back to an old cold case. While investigating, Benson (Mariska Hargitay) and Amaro (Danny Pino) meet a one-legged prostitute who is quick to admit she lost the leg for a price.
