In 1988, several people simultaneously hemorrhage to death in Philadelphia. Police officer Thomas Lockhart believes the case to be his ticket to becoming a detective, though his partner, Maddox, is less enthusiastic. Lockhart’s brother-in-law, Detective Holt, initially dismisses Lockhart’s observations but eventually admits the deaths are connected when Lockhart finds similar wounds on each victim. Lockhart and Maddox find an assault victim with similar wounds; before suddenly dying, she describes her assailant as a twenty-something African American woman with a wounded hand. After Holt organizes a citywide manhunt, Lockhart and Maddox chase the suspect into a subway, where she subdues Maddox. When Lockhart confronts her, the suspect reveals details about his life, including that his wife will give birth that day. She predicts her own death just prior to a struggle, which ends with a train hitting her. Although confused about the many unexplained details, the police close the case. Meanwhile, Lockhart’s wife dies in childbirth.
