99 Women

On an island off the coast of Panama are situated two penal colonies. Supervising the women's penitentiary is the sadistic Thelma. Overseeing the brother institution is a lecherous warden who disports himself with inmates of the women's prison.
When a number of prisoners die under suspicious circumstances, the cruel Thelma is replaced by liberal penologist Leonie, who retains the former supervisor as her assistant. Leonie's indulgence is her undoing. She is accused of a lesbian relationship with Marie, an inmate whom she has naively befriended.
Accompanied by prisoners Helga and Rosalie, Marie attempts an escape into the surrounding jungle. One of the fugitives dies of injuries sustained during her rape by a gang of male convicts; the remaining escapees are recaptured and flogged.
After a prison riot occurs Leonie is dismissed and Thelma reinstated. Nevertheless, Leonie learns of impending penal investigation and reform.
