Although the psychologist Jennifer Walters is imprisoned in a women's prison, she is allowed to continue her profession internally due to good conduct, as well as to move freely within the complex. Not very enthusiastic about the conditions in prison, she listens to the hair-raising stories of a young girl named Anna in sessions, who is being treated for severe depression with her. Stories come to light that are not for everyone. Jennifer analyzes the conditions and documents torture, rape, homosexuality and sex orgies. In addition, Jennifer is very fond of the girl and wants to help her.
