As the summer rolls on Georgia (Jane Fonda) attempts to wrangle her out-of-control granddaughter into submission by laying out ground rules and getting her a job in a local office. The girl, refusing to abide by the rules, attempts to make her own fun in a town that has a much more wholesome definition of a good time than she is used to. Rachel slowly begins to befriend the townspeople, specifically her boss, Simon (Dermot Mulroney). There, in Mormon Hull, Idaho, Rachel reveals a deep, dark secret that may explain her unpredictable and often self-destructive behavior.
Upon hearing rumors of a scandalous affair between her child and her husband, Lily returns to Mormon Hull to try and figure out what is going on. Georgia admonishes Lily for her lack of parental guidance, which may or may not be fueled by alcoholism and other addictions. The women grow closer and Rachel begins to feel her place might just be in this small town that seemed so boring and conservative just a month prior.
The film was originally intended to highlight the mother, daughter, granddaughter triangle and the differing parenting styles (Lily's permissiveness vs. Georgia iron fist), but the subplot of the scandalous affair take root much more strongly and become the shining star of the film.
