I saw this movie when I was little but don't remember the title of it. It's about this teen girl that gets raped by one of her father's friends and she writes about it in her journal. She eventually hangs herself in the backyard of her home. Her family finds her diary and finds out about it and goes and beats the crap out of the guy. Do you know the name of this movie?

It's Once Were Warriors (1994) (http://www.imdb.com/title/tt0110729/)
