Barney Kempinski, thirtyish and contentedly self-unemployed, leaves his Lower East Side apartment smiling and happy. On this fine sunny day he is to be married - 3 o'clock at City Hall - to his girl Francine. In the few remaining hours of his bachelorhood, Barney goes off to tour the city and sing his love song - exuberant, irresponsible and frequently dangerous - to life, love and the city of New York.
