I saw this movie back in 2007 I’m not sure what year it came out but all I remember is close to the end of the movie the mother went out to the store I believe and either the so called father or stepfather which ever one he was made the daughter preform an act on him and the brother saw them and got a gun and killed the father.
I don’t know the answer, but please don’t post the same question again if your movie question is still on the first page. Wait a week or so. If no one answers in 48 hours or so, it usually means no one has a clue, unfortunately.
