Everyone needs to be accepted, especially by their mothers. That is a basic need that is characteristic of all humans. Some people are denied this, which was the case for Arlene, the protagonist.
While young, probably still in her teens, Arlene -- then known as Arlie -- landed in prison. She fought authority constantly and suffered through the harsh disciplinary measures of the prison system. By the time she got out, she had changed her outlook considerably, and wanted to be called Arlene.
The play concentrated on Arlene as she moved into her post-prison apartment and took her first uncertain steps as an ex-con. One of her former prison guards took her to her new place, then tried to force himself on her. Her pre-prison boyfriend, a small time hood, showed up and tried to draw her back into his abusive snare. Arlene's earlier self -- Arlie -- was constantly in the background, replaying scenes from the past.
This is a short (64 pages) but tough play. To really absorb it, would have to read more than once. The play spent a long time on Broadway, which I've never been to. If the play was still there, I would go.
