It starts in a nice suburb, and goes into a nice home w/ a little girl, teenage daughter, teenage brother, mom and dad ( high class family) then they go to bed a you hear a window crash. 2 guys break in their house. The 2 guys torture and rape everyone in the house, do sick stuff, then you hear another window crash in the house, and it's the two guys friend who broke out of prison, and that guy takes his turn torturing and raping the family. In the end the little girl escapes and runs out the house, and then gets shot in the back by the guys, then it shows the guys smiling and that's the end of it.

I haven't seen this one so I don't know how it ends but try If I Die Before I Wake (1998) (http://www.imdb.com/title/tt0137827/)
