Detective Rachel Scott had been on the force for over a decade, but nothing had prepared her for what she saw when she arrived at the crime scene. It was a small, cozy apartment on the third floor of an old building, and the victim was a young woman in her mid-twenties. Her body lay sprawled on the floor, a deep wound in her neck. Rachel couldn't help but feel a sense of unease. She knew that this was going to be a difficult case.
As Rachel and her partner, Detective Jake Collins, begin their investigation, they find that the victim, Emily, was a talented artist who had recently begun to gain recognition in the art world. But as they delve deeper into her life, they discover that Emily had a dark past. She had been a victim of domestic violence and had been in and out of abusive relationships.
Rachel and Jake interview Emily's ex-boyfriend, who was known to be abusive. He denies any involvement in her murder but Rachel can sense that he's not telling the truth. As they continue their investigation, Rachel begins to receive anonymous messages and calls, warning her to back off the case. She tries to shake it off, but her nervousness grows.
The detectives are led to a suspect, a man who had been stalking Emily for months. He had been sending her threatening messages and had even broken into her apartment. Rachel feels like they have finally found their killer, but when they go to arrest him, they find that he has an alibi. Rachel's nervousness grows as she realizes that they might be dealing with a serial killer.
As the investigation continues, Rachel begins to notice a pattern. All the victims had been women who had suffered from domestic violence in the past. Rachel's nervousness grows as she realizes that the killer might be targeting victims based on their past. Rachel and Jake interview a victim who had survived an attack by the killer. Her account provides them with new evidence that leads them to a potential suspect. They work tirelessly to build a case against him, but Rachel's nervousness grows as she realizes that the killer might be watching them.
Rachel receives another anonymous message, this time with a picture of her own apartment. She realizes that the killer knows where she lives and that she's in danger. Her nervousness turns to fear as she tries to protect herself and her family.
As Rachel and Jake close in on the suspect, they find themselves in a dangerous game of cat and mouse. The killer is one step ahead of them, and Rachel's nervousness turns to desperation as she tries to catch him before he kills again.
Rachel and Jake finally catch the killer, but not before he kills one last victim. Rachel's nervousness turns to anger as she realizes that they were too late to save the victim. She vows to bring justice to all the victims and to make sure that the killer never sees the light of day again.
