Joan takes her first solo case: the disappearance of a woman who left her husband a tearful break-up video that mentioned a murder on a subway platform. Meanwhile, Sherlock is intrigued by the subway murder and decides to investigate.

A dancer is followed home and raped by a man with a distinctive tattoo and the details of the attack remind Rollins (Kelli Giddish) of a serial rapist she was tracking back home. The detectives arrest Gabriel Thomas (guest star T.R. Knight), a family man who maintains his innocence, but his description and DNA match this assault and the string of rapes across multiple states that Rollins had been investigating. Although the evidence supports the arrest, the more Detectives Benson (Mariska Hargitay) and Amaro (Danny Pino) dig into Thomas' past, the more they begin to believe his story. Also starring: Ice-T (Detective Odafin Tutuola), Dann Florek (Captain Donald Cragen) and Richard Belzer (Detective John Munch.) Special appearance by Diane Neal (ADA Casey Novak.)

When an airline pilot (guest star Yasmine Al Massri) accuses her captain (guest star Martin Donovan) of sexual assault, Barba (Raúl Esparza) convenes a Grand Jury to determine their employer's complicity in the crime. Meanwhile, Fin (Ice T) takes steps to ensure Benson (Mariska Hargitay) is protected at work.
