I stumbled upon this movie while looking up corny 80's movies on Letterboxd and the poster was just too good to pass up.
In short - this movie is completely bonkers.
It's about two rich teenage sisters who are sent to a private school where the principal is dealing drugs, selling porn and being in general really weird. There is also a narrator who has an odd fascination with goats, a trip to a greek island without any explanation, and yeah this is Patricia Arquette's first ever role in a movie. I'm not even sure if this is a movie for teens at all, since there is so much nudity going on as well.
