The Big Doll House is a 1971 American women-in-prison film starring Pam Grier, Judy Brown, Roberta Collins, Brooke Mills, and Pat Woodell. The film follows six female inmates through daily life in a gritty, unidentified tropical prison. Later the same year, the film Women in Cages featured a similar story and setting and much the same cast, and was shot in the same abandoned prison buildings. A nonsequel follow-up, titled The Big Bird Cage, was released in 1972.

Plot

Collier (Brown) enters prison, having been found guilty of killing her husband. She is introduced to the beautiful occupants of her cell, doing time for crimes ranging from political insurgency to heroin addiction. The women often clash, which leads to their torture by sadistic guard Lucian (Kathryn Loder). The torture ceremonies are viewed by an impassive cloaked figure.
