Paz de la Huerta (“Boardwalk Empire”) turns up the body heat in this wickedly entertaining story of a fatal attraction. By day, nurse Abby Russell (de la Huerta) lovingly attends to the patients at All Saints Memorial Hospital; by night, Abby prowls nightclubs, luring unfaithful men into dangerous liaisons. After Danni – a young, sensitive nurse – joins the hospital staff, Abby pursues her friendship. However, when the friendship turns to obsession, Danni spurns Abby, unleashing Abby’s fury and a rampage of terror.
