Director Irene Taylor Brodsky tells Buzzfeed of the documentary: “The narrative does not revolve around guilt or innocence, but instead the court’s deliberation whether the girls should be tried as adults or children. Above all, it is the anguish and astonishing honesty of the girls’ parents that anchors the film’s narrative to its tragic core.”
