For a three-act plot analysis, put on your screenwriter’s hat. Moviemakers know the formula well: at the end of Act One, the main character is drawn in completely to a conflict. During Act Two, she is farthest away from her goals. At the end of Act Three, the story is resolved.
Act I
Bernice's thoroughly uneventful visit suddenly explodes with eventfulness – after her fight with Marjorie, she promises to do everything her cousin tells her in order to learn the art of popularity.
Act II
The plan works, and Bernice's idyll lasts until Marjorie turns against her. Act II ends at the barber shop, where everyone is gathered to watch Bernice bob her hair.
Act III
Act III is our favorite – shorn and infuriated, Bernice abandons all of her inhibitions and runs away…but first she cuts off her cousin's beautiful hair.
