The movie I am talking about is a horror movie in the end of the movie girls tries to escape from men want to kill them and all girls dead and men killed except man and girl. The girl found a car a man try help her too stop the killer and the girl run to a house to found a wife to found she the wife of the man who try to kill her then she hit the killer and his wife to tried to escape and fall in a Swimming pool and she fight him until she killed him. After that suddenly the wife hit her with A sharp tool and this is the end of the movie. I think some of the characters names was Kat or Kate , Lilli , Ethan, Jack, Tory as I remember and it is a modern movie I mean during 2000s or 2010s not before that .
