The murderer is outside the door

Helen (Sigourney Weaver) is a criminal psychoanalyst. Over the years, she has solved many serial murders with her excellent reasoning skills. While winning a reputation for herself, she was also attacked by villains. After that, the frightened Helen decided to live at home without leaving home, relying on a powerful network to complete her work and life. In this way, many years passed. Recently, several murder cases that have occurred one after another have given policewoman Jenny (Holly Hunter) a headache. She had no choice but to seek help from the experienced Helen. Various clues showed that this case was inextricably linked to cases that Helen had handled. With Jenny's persuasion, Helen decided to stand up and find out the truth of the incident. But what the smug Helen didn't know was that the terrible murderer had already come to her.
