The film opens with Abby Russell at a night club where she explains to the audience via a narration that her “job” is to murder cheating men in order to “keep scum off of the streets”- a job that she thoroughly enjoys. She then murders a man by slicing through his femoral artery and then throwing him off the roof of the club. The following day she attends a ceremony where she watches Danni Rodgers, a nurse she had been mentoring, graduate. She then approaches her and meets Danni’s mother and stepfather Larry Cook. Despite this joyful moment and all of her preparation, Danni is ill prepared for her first true day of nursing duty and is berated by Dr. Morris for her inability to respond quickly to an emergent situation. Abby views the situation with disgust, as she knows that Dr. Morris is a sadist that enjoys harassing new nurses.
