" Agnes Under the Big Top: A Tall Tale " explores the intersecting lives of several immigrants in a US city. It is a magical tale of hope and disappointment, identity and reinvention, narrated by an itinerant subway busker. Against the subterranean rhythms of a subway train, a Liberian home care worker, a former Bulgarian ringmaster and his wife, an Indian call center escapee, and a bed-ridden American woman, find and redefine themselves in today's America.
