"The Power and the People: 1898-1914" recalls the era of mass immigration. "The entire world would arrive on the city's doorstep," says narrator David Ogden Stiers (1.2-million in 1907 alone). "There was a message," says writer Pete Hamill. "Come here, everything is possible." The program also follows the political career of "Happy Warrior" Al Smith; and charts the construction of the subways and the rise of skyscrapers in the clogged city.
