Some light occasional sexual innuendo.

A guy and lady are shown in bed a few times.

A guy lady get romantic, lovey dovey kissing (maybe a french kiss or two).

A guy and lady dance a bit intimately.

Some occasional fist fights and gun fights. A guy shoots another guy (some blood spurts). A guy strangles another guy. A lady smashes a guy with a clock. A guy strangles a lady and chases after her.

There's occasionally some blood but nothing real heavy. We see two somewhat bloody bodies (one alive the other dead in pictures)

13 F-words (a few used sexually) and some other lighter adult language ("shit," "ass," "damn," "bitch") but nothing really extreme compared to other extreme hard R-rated films.

Smoking.

Some occasional drinking (there are scenes at bars); nothing really extreme or crude.

The entire film kind of keeps you at the edge of your seat and is a bit tense, especially the last 15 minutes. It really isn't too intense, extreme, and nasty but its pretty mysterious and suspenseful.
