When Dr. Peter Fales’s patients start getting annihilated by an unknown serial killer, he and his daughter Alison both come under suspicion. Julie, a syndicated “Dear Abby”-style columnist, is in one of Dr. Fales’s therapy groups. After she receives several ominous letters she not only wonders if Dr. Fales might be behind the killings, she also starts to suspect her estranged husband.
