740 Park Avenue - an exclusive apartment building in Manhattan - is currently home to more billionaires than any other building in the United States. Less than five miles to the north is another Park Avenue in the South Bronx, where almost 40 per cent live in poverty and life prospects are less promising for those stuck at the bottom of the American pile. Through archive and interviews with academics, political scientists, psychologists, former lobbyists, and even a former doorman at 740 Park, filmmaker Alex Gibney's film is a polemical look at the socio-economic political landscape of contemporary USA.
