The Big Doll House is a 1971 women-in-prison exploitation film directed by Jack Hill that was shot in the Philippines. The story takes place in a brutal overseas prison where the vicious prison guard Lucian (Kathryn Loder) and her cohorts maintain an iron grip. The film follows a new prisoner, Collier (Judy Brown), as she learns the harsh realities of life inside the prison and eventually forms an alliance with her fellow inmates (including Pam Grier in her first major film role) to plan a daring escape. The movie, with its lurid and violent content, is considered a classic of the exploitation genre and set the stage for many similar films that followed. If you enjoy this movie, definitely check out Jack Hill's follow-up women-in-prison movie The Big Bird Cage (1972), also starring the great Pam Grier.
