The early lives of Theodore Roosevelt and his younger cousin, Franklin.

Theodore Roosevelt becomes one of the most beloved presidents of the United States, building the Panama Canal and preserving American wilderness; Franklin Delano Roosevelt weds Eleanor, enters a law firm, and considers running for senator.

Theodore Roosevelt campaigns for America to enter World War I; Franklin Delano Roosevelt serves as Secretary of the Navy; Theodore's death at age 60 provides Franklin with a major opportunity.

Franklin Delano Roosevelt runs for vice president in 1920, but he contracts polio; while serving as governor of New York, Democrats turn to him as their presidential nominee for 1932.

President Franklin Delano Roosevelt's New Deal restores people's self-confidence; as the 1930s come to a close, FDR faces two issues -- whether to run for a third term and how to deal with Adolf Hitler.

President Roosevelt prepares the U.S. for its entry into World War II; Eleanor pushes to keep the New Deal reforms alive in wartime; FDR learns that he has congestive heart failure in 1943 but decides to run for a fourth term.
