Already established as America's premier port, New York City swelled into the nation's greatest industrial metropolis as a massive wave of German and Irish immigration turned the city into one of the world's most complex urban environments, bringing with it a host of new social problems. Episode Two reveals how the city's artists, innovators and leaders, from poet Walt Whitman to Frederick Law Olmsted and Calvert Vaux (the designers of Central Park) grappled with the city's growing conflicts -- which culminated in the catastrophic Civil War Draft Riots of 1863.

In exploring the social, economic and physical forces that swept through the city in the post-war period, Episode Seven examines the great African-American migration and Puerto Rican immigration of the '40s, '50s, and '60s; the beginnings of white flight and suburbanization; and the massive physical changes wrought by highways and urban renewal -- all of which were directed, to a surprising degree, by one man: Robert Moses. The film comes to a climax with the destruction of Penn Station, the battle over the Lower Manhattan Expressway, the social and fiscal crises of the '60s and '70s, and New York's miraculous revival in the last quarter-century.
