Six young black men from Akron, Ohio, enter college, determined to redefine society’s images and low expectations. Despite their confidence, the stark reality of being away from home brings a series of crises. Well trained in critical and metaphorical thinking, and unusually articulate about their inner lives, each of the protagonists guides us to his core.

Brooklyn Castle is a documentary about I.S. 318 – an inner-city school where more than 65 percent of students are from homes with incomes below the federal poverty level – that also happens to have the best, most winning junior high school chess team in the country.

But a series of recession-driven public school budget cuts now threaten to undermine those hard-won successes.
