A serial rapist is terrorizing single women in Lower Manhattan. Nicknamed the Zodiac Rapist, after the cards left at each scene, detectives at the 35th precinct are working around the clock to catch the attacker. What is the significance of the Gemini and Sagittarius cards left at each scene and what links the star signs and the victims? Detective Mike Garcia and his team are no closer to figuring it out when Detective Ethan O'Connell transfers to their team. O'Connell's first day on the job starts off with a gruesome double homicide, but the crime scene is almost identical to a scene he'd seen 10 years ago to the day. The day his parents were murdered. Is the scene set up for him, or is it merely a coincidence? As the rapist's pattern emerges, the team set up a plan to stop the next attack when they start receiving taunting calls, mocking their pathetic attempts to stop him. How does he know what they're doing? How is he one step ahead each time? Is he a cop or is someone in the department feeding him information? One thing is clear: O'Connell is in the middle of it and no-one knows who to trust. Are the rapist and the murderer the same person, or are they chasing two faceless demons? Gemini and Sagittarius.
