Twisted (2004 film)
Plot
Having solved a high-profile case involving serial killer Edmund Cutler that ended with her being taken hostage by Cutler but managing to overpower and arrest him, officer Jessica Shepard of the San Francisco Police Department is transferred to the homicide division and promoted to the rank of inspector. SFPD Commissioner John Mills, her foster father and her deceased father's former partner, also serves as her proud mentor. Shepard is an alcoholic and nymphomaniac, carrying the emotional burden of her father murdering some of her mother's extra-marital lovers, then Shepard's mother and himself.
Plot
When one of Shepard's former one-night stands is brutally murdered, Shepard and her new partner, Mike Delmarco, are assigned to the case. Shepard admits that she had slept with the victim yet remains assigned to the case. A few days later, another of Shepard's numerous one-night stands is murdered and soon the police come to the conclusion that the killer is stalking Shepard. At Mills' insistence, Shepard remains on the case to bait out the killer.
Plot
As investigations progress, Shepard keeps having alcoholic blackouts at night, having already had them on the nights of the two murders. She confides this to Mills, who encourages her to carry on.
