Movie in the 80s or 70s - there is a girl who seems to be the main focus of the movie. She plays the piano and her piano teacher holds sharpened pencils under her wrists so that if they drop while she is practicing she will get poked by the pencils. The teacher is very stern. For some reason I feel like there was a bit of past life regression, the piano teacher was also a Nazi. Somehow the girl's family is threatened to do something but they don't do it. They are then run off the road by a car that we assume is part of this dark government agency, and they are killed. Thanks!
