While investigating a jewelry heist by a young Asian woman, Ella, and her partner who is later found murdered, Goren and Eames discover that Nicole Wallace is involved. During the course of their investigation, the detectives discover that Nicole had a child years earlier, who drowned at three, and they suspect that Nicole killed her. Using this information, the detectives try to convince Ella, who is Nicole's lover and a surrogate for her dead daughter, to help them bring Nicole down.
