Plot summary
Detectives Robert Goren and Alexandra Eames investigate a diamond heist in a house that left two occupants and one thief dead. The criminal who planned the robbery, Karl Atwood ( Jake Weber ), jumped parole in Canada and crossed the border and attempted to deceive the police into believing the theft is related to the mafia. Goren and Eames track down and interview Atwood's girlfriend Gia ( Michele Hicks ) and suggest to her that Atwood contracted AIDS in prison and has infected her, offering leniency and medical treatment if she helps them arrest Atwood. She leads them to Atwood, and when diamond buyers appear, Goren and Eames arrest them all. Goren then informs Gia that he lied about her being infected with HIV. Special appearance by Dianne Wiest as DA Nora Lewin
