Twisted

Jessica, whose father killed her mother and committed suicide, is a police officer. While investigating a murder, she finds herself in the center of her own investigation, when her former lovers start being murdered.
Recently promoted and transferred to the homicide division, Inspector Jessica Shepard feels pressure to prove herself -- and what better way than by solving San Francisco's latest murder? However, as Shepard and her partner, Mike Delmarco, soon discover, the victim shared a romantic connection to her. As more of Shepard's ex-lovers turn up dead, her mind starts to become unstable, and she begins to wonder if she could be the very killer she's trying to track down.
