For 11 years, Beth's life is limited to working nights in a convenience store while her daytime hours are spent caring for her bed-ridden, bitter and abusive mother. All that keeps her going is a voice on the radio. The voice belongs to a psychologist, Dr. Roland, who has a call-in radio show. Beth listens intently to the advice given to every caller hoping that something said might help her work through her personal problems. Beth's obsession with Dr. Roland grows to the point where nothing, not even murder, will stop her from gaining access to the doctor she's never met.
