From NetFlix:

Frannie (Meg Ryan) is a New York writing professor entwined in an erotic affair with a police detective (Mark Ruffalo) who’s investigating the murder of a young woman in Frannie’s neighborhood. But soon Frannie begins to suspect her lover’s involvement in the crime. Kevin Bacon and Jennifer Jason Leigh also star in this highly charged film directed by Jane Campion (The Piano) and based on Susanna Moore’s best-selling novel.

Sex – that’s mostly what this film is about. That and a lot of gory murders by a serial killer. You need a strong stomach for this film. Visually there is explicit sex. Verbally there is a lot of very frank sex talk and cursing.

So why would anyone in their right mind watch this gore-sex fest ? Well – Meg Ryan, Mark Ruffalo, Kevin Bacon and Jennifer Jason Leigh (as Pauline, Frannie’s sister) do a fair job of putting together a tense “who done it”. The core of the problem is that Meg Ryan is surrounded by a lot of characters, any one of whom could be the serial killer. This list of suspects includes Mark Ruffalo with whom she is having an affair. As much as you might guess the ending it is still scary.

But you have been warned that this film might offend you.
