In New York City, in the 1840s, people need a diversion from the "railroad pace" at which they work and live. They find it in a game of questionable origins. On June 19th, 1846, at the Elysian Fields in Hoboken, New Jersey, a team of well-dressed gentlemen, the Knickerbockers, play the first game of baseball. By 1856, the game is already being called "the national pastime," or simply, "Our Game." But the nation is about to be torn apart. And, in the midst of the Civil War, there is one thing that Americans North and South have in common: baseball.

It is a decade of revolution. In China, in Central America. At Kitty Hawk. In Henry Ford's factory. And on America's baseball fields. In 1894, a sportswriter named Byron Bancroft "Ban" Johnson takes over a struggling minor league - the Western League - and turns it into a financial success. In 1900, he changes its name to the American League and begins talking about challenging the big city monopoly held by the National League. The revolution takes only three years. In 1903, the first World Series is played between the American League Boston Pilgrims and the National League Pittsburgh Pirates.

This episode concentrates on Babe Ruth, whose phenomenal performance thrilled the nation throughout the 1920s and rescued the game from the scandal of the previous decade.

The story of the Negro Leagues in the 1930s. “Shadow Ball” refers to a common pre-game feature in which the players staged a mock game with an imaginary ball. Though unintended, the pantomime was an apt metaphor for the exclusion of blacks from major league play at that time.

This episode covers the 1940s and includes Joe DiMaggio's celebrated hitting streak, the awe-inspiring performance of Ted Williams and what Burns calls “baseball's finest moment” — the debut of Jackie Robinson, who broke the color barrier as a member of the Brooklyn Dodgers in 1947.

Viewers are taken through the 1950s when New York City had three successful baseball teams and dominated the World Series. By the end of the decade, the Giants and Dodgers had left New York, a signal that the old game was changed forever.

The field is moved to the 1960s. This episode traces the emergence of television, the expansion to new cities and the building of anonymous multipurpose stadiums that robbed the game of its intimacy and some of its urban following.

The final episode looks at baseball from the 1970s to the present, including the establishment of the free agent system, the rise in player salaries, the continued expansion, the dilution of talent, the ongoing battles between labor and management and the scandals.
