I remember watching a movie in the 1990s where these girls were at a school or something, and they were being tortured. I remember them being naked in a spiked wall that closes in on them. I honestly don’t remember much more than that. I thought there was a famous singer in the movie, but I might be wrong. I watched it in the 90s, but that doesn’t mean it was made in the 90s.
