Detectives Briscoe and Curtis investigate when the partial remains of a woman are found in the river. The autopsy reveals the woman was cut up with a large knife, like a machete, and was likely cut up when she was still alive. She had cosmetic surgery and they manage to identify her as Heidi Ellison, the president of a Mattawin Studios in Hollywood. They focus on her personal trainer, Evan Grant, but he goes off to Los Angeles before they can get a blood test from him. The detectives follow him there but have trouble getting the blood sample when the court order ADA McCoy obtained is quashed. They find a way around that and Grant is returned to New York. He may have a reasonable alibi however. They then focus on Ellison's ex-husband, director Eddie Newman. Curtis meanwhile ends up on a date with an attractive studio executive, Lisa Lundquist.
