Lincoln (Denzel Washington) was paralyzed due to work. He was once a famous detective who solved countless cases, but since he was paralyzed, he has closed himself off. This time, he was invited by the New York police to help with a mysterious murder case. At first, Lincoln refused the invitation, but after seeing the case, he became emotional about the case. A mysterious dismemberment case has recently occurred in New York, and the murderer deliberately left evidence to challenge the police. Patrolman Emilia (Angelina Jolie) found a dismembered body during her last patrol, but when she made a series of bold speculations, her colleagues were unwilling to pay attention to her, thinking that she was just an unknown patrolman. However, Emilia's sensitivity and courage were appreciated by Lincoln, and he asked to work with this novice to break through the case. The two cooperated surprisingly happily, and finally learned that the killer has a tendency to violence, and will make careful arrangements before killing. Can they successfully catch the perverted murderer with their tacit understanding?
