Its about a movie a girl who somehow moves in with a couple and is crazy. Has an affair and eventually tries to kill them I think. It is sometime after 2010.
Some descriptions of movie on reddit with no source:
The couple just moved into a new house and let a friend stay with them. The friend starts dating this girl. The girl is like bat-shit crazy. I think she kills the guy? Around the end of the movie she gets in the shower with the husband and they start having sex. He stops it and she goes crazy and tries to kill him. What is the name of this movie? EDIT: It is a newer looking movie I saw on Netflix. I'm assuming it wasn't very popular. The cover for it was a attractive brunette girl holding a knife behind her back.
I don't remember the exact circumstances, like... why this girl ended up moving in with this couple. I just remember a few "specific" details. Like a scene at night in the couples' swimming pool, don't remember who it involved, just know it happened. I also remember a part where the girl goes into the husbands' work, i think he was a doctor or something, and they start talking in an elevator or something? Sorry for being so vague. I watched this movie roughly two years, it was on Netflix at the time, no idea if it still is. I don't know why all of a sudden I'm interested in watching it again, but I am.
