An extended sleepover turns tragic for two sisters in this fact-based tele-film. After their carnival worker parents separate, Sylvia (Juno's Ellen Page) and Jennie Fae Likens (Hayley McFarland) move in with Gertrude "Gertie" Baniszewski (Emmy nominee Catherine Keener), a divorced Indianapolis mother with seven children (six in the screenplay). The kids get along, so the Likens figure Gertie will offer a safe haven until they return. Little do they realize she has a substance-abuse problem, a history of mental illness, and a layabout lover (James Franco). Even with the money the Likens send and the washing she takes in, Gertie can't make ends meet, so she takes her frustration out on her boarders. Since Jennie has polio, Sylvia bears the brunt of her anger: beatings, cigarette burns, and worse. Then when Sylvia tries to protect Paula (Nick and Norah's Ari Graynor) from an abusive boyfriend, Paula turns against her, too (Sylvia tells him about Paula's pregnancy). Like dominoes, the rest of the extended family falls in line. Three months later, their torture culminates in murder. Throughout, the narrative alternates between 1965 and the ensuing court case, in which prosecutor Leroy K. New (The West Wing's Bradley Whitford) cross-examines witnesses and defendants, whose testimony comes from the original transcripts.
