Introduce several movies related to voyeurism.

Plot: Franny Avery (meg ryan) is a college literature teacher in New York State. She lives in a small apartment in Manhattan, and her life is monotonous. She was accompanied only by her sister Paulina (jennifer jason leigh). At present, she is writing a book, studying new york youth slang and collecting information.

Once, Franny came across an adulterous man and woman in the bathroom of a bar. She peeped quietly from the side. Although she didn't see the man's face clearly, the man with the tattoo on his wrist strongly aroused her desire.

Then, in Franny's garden, a dismembered female body was suddenly found. Detective Malone (Mark Ruffalo) came to investigate. Franny accidentally found that the tattoo on Malone's wrist was the same as the man in the bar bathroom, and she felt a little uneasy. The two were quickly attracted to each other and involved in the whirlpool of passion. Crazy sex makes Franny surprisingly rejuvenated, and she can't help falling into it. A series of similar female murders keep happening, and each victim has more or less contact with Franny.

After being attacked by masked kidnappers, Franny seems to feel that everyone around her can't escape the suspicion of murder and no longer trusts anyone around her. Including her young student Dick Nelis (played by Sharif Pew), who is writing a paper on the innocence of serial murderers; John graham (kevin bacon), a disturbing ex-boyfriend who is always around her; Even detective Malone, a clue to a serial killer, can make her suspect.

Frannie fell into a painful struggle of love and fear, but courage and independence finally overcame everything. The brave and decisive Franny had to uncover the true identity of a serial killer alone.
