Women in Fury (1985)

Believing she'll receive a more lenient sentence, a young woman
named Angela Duvall (Suzane Carvalho) takes the rap for her
addicted brother after he murders a drug lord. We immediately
realize Angela's exceptional beauty is going to cause her problems
since even on the way to the slammer, a police officer in the
prison transport truck lasciviously leers at her gorgeous thighs.
She winds up in a Brazilian penitentiary hell hole where she's
subjected to the obligatory strip search.  Naturally, she immediately
attracts the unwanted attention of everybody from two feuding
prison dykes to the lesbian head matron.  (IMDB)
