Academy Award-nominated actors Christopher Plummer and Karen Black join forces in this suspense thriller about the murder of a prostitute with Satanic overtones. Police sergeant Henderson (Plummer) investigates the murder of prostitute Elizabeth Lucy (Black). Around her neck, she was wearing an upside down cross, and clutched in her fist, a locket, both unusual for a high class call girl. Flashbacks expose incidents from Elizabeth's life in the days prior to her murder in which she and Henderson enter a world of devil worship and decadence. Based on the novel by John Buell.
