A female police officer, Jessica Shepard (Ashley Judd) is moving up in the ranks, most recently being assigned to the homicide unit, despite her drinking problem and troubled personal life. Shortly after her latest promotion, Jessica is surprised when the victim in a murder case she is assigned to turns out to be one of her many one night stands. Jessica becomes increasingly concerned when additional murders take place and the victims are all men she has slept with. As she begins to fear who will be next in this string of murders, others in the department begin to wonder if Jessica herself has any involvement in the crimes.
