Is there a doentary showing what abuse (not ual) really is?

My step-daughter screams abuse every time she does not get her way or has a meltdown. She continually threatens to call CPS on us when she is angry, and has gone through with it. The case is always closed because she is NOT abused! I want to show her what real abuse is, and how serious these accusations are. She doesn't seem to realize how serious it is to accuse some one of physical abuse, and to get the school/police/CPS involved just because she is mad at us for grounding her for getting all F's on her progress report. Does any one know of a good doentary or movie that can teach and show her that she has a wonderful life with parents and many people who love her and do not abuse her? She needs to know that there really are children who are abused, and by crying wolf, she is taking away valuable help and resources for the kids who really need help.
