This sweet film, by Katie Dellamaggiore, looks at a program at one junior-high school in Brooklyn that has excelled in producing nationally competitive chess players. You might come to this POV program expecting a chess version of Fame, with driven students fighting their way to Nationals. But what you get, in addition to that, is a story about dedicated teachers, parents who inspire and sacrifice to help their kids do well, and federal and state politicians and programs that drain these programs of money, and thus life. You end up rooting not only for the kids of I.S. 318 in Brooklyn, but for parents, teachers, students and extracurricular school activities everywhere. Check local listings.
