Surveillance
The brutal attack of a young cellist, Cassie Germaine (guest star Emily Deschanel) in her apartment leads Detectives Benson (Mariska Hargitay) and Stabler (Christopher Meloni) to investigate her orchestra conductor Robert Prescott (guest star Michael Nader). The relationship between the two, coupled with Prescott's penchant for amateur erotic filmmaking, causes suspicion when a scan of the victim's apartment reveals a series of hidden cameras recording her every move.
