House of Women (1962)

Sentenced to five years in prison, Erica Hayden is most worried about her unborn child's future. At this prison, they allow the women to keep their children until age 3 but at that point they must be given to a friend or relative outside the prison or surrendered to State authorities who will arrange an adoption. She tries desperately to find someone and the prison doctor even tries to help her. One person who isn't keen on the arrangement is the new prison warden, Frank Cole, who thinks prison is no place for young children. Her only hope is that she will get parole after three years but when it's refused and her child is taken away without even giving her the chance to say goodbye, the women stage a riot.
