The Big Doll House (1971)

Red-haired woman Collier (Judy Brown) is sentenced to 20 years of hard labor in a Philippine prison on murder charges. Her cellmates are all beautiful, sexy and fierce young girls, and the strong black woman Grier is their boss. Grier wants to take Collier as his new pet. Collier is not afraid of debauchery and soon becomes friends with the fierce but righteous Bodine (Pat Woodel). Alcott, a loner blonde, is actually very calculating. One day while working, she successfully challenged Grier and subdued her, becoming the new boss of the cell. Harry and Fred, who sell goods to prison inmates, are two little perverts. Harry coveted Grier's beauty and promised to help him escape. One day the perverted female police officer took Collier away and planned to extort a confession by torture, and all his cellmates were locked in the steam room. The isolated Grier also wanted to help, but was cut to death by his former attendant. Time is running out, Bodine, Alcott and others began to rescue Collier and escape from prison.
