Jailhouse Eros (1990) was an Amy Yip starring vehicle. She plays Chesty, an inmate inside a women's correctional facility.
I'm afraid I don't have much patience for scriptless crap like this. It's so obvious that the producers thought throwing busty Amy Yip into a prison of relatively gorgeous women and adding a ghost plot was all they needed to get punters stampeding their way to the box office.
