Filmmaker Charlotte Glynn moves home to chronicle her sister Rachel's last year in school. Rachel is developmentally disabled, and the resulting film, Rachel is, moves past the safety of political correctness and into the most intimate and honest moments in their family's life. Rachel is mysterious, funny, difficult and full of contradictions but she wants what most people her age want -- to move out of her mother's house. This dream of independence seems impossible. Rachel can't be left alone and the social services needed for her to live an "adult life" are unavailable.
