Barbed Wire Dolls หรือFrauengefängnis (1976)
Plot/Synopsis:
One of cult director Jesus Franco’s best-known efforts.
It seems like a standard women’s prison tale with Maria jailed for life after killing her father when he tried to rape her. There’s a lesbian warden, more rape, torture, insanity, and so forth, with the obligatory conspiracy and a downbeat twist ending to round out the formula.
What makes this film different from many others in the subgenre is its unremitting atmosphere of despair and sleaziness… and — in an expectedly tacky bit of casting — the director himself as Maria’s lecherous father. ~ Robert Firsching, Allmovie
