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.

Examine the century's second decade, which was dominated by the Black Sox scandal. George Herman “Babe” Ruth makes his first major league appearance (as a member of the Boston Red Sox) and a wave of immigration helps fill the stands with new fans, eager to “become American” by learning America's game.

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.
