Over the course of three years, filmmaker Meghan Eckman tracked the comings and goings of a solitary parking lot in Charlottesville, Va., chronicling the lives of the attendants who were working there. This inspiring documentary is the result. Hanging tough as they navigate the range of human emotion -- from hope to frustration, from a sense of limitless possibilities to stagnation -- the film's subjects embody the pursuit of the American Dream.
