Brought to the White House to receive a Congressional Gold Medal from President Franklin Delano Roosevelt, Broadway legend George M. Cohan (James Cagney) reflects on his life. Flashbacks trace Cohan's rise, from a childhood performing in his family's vaudeville act to his early days as a struggling Tin Pan Alley songwriter to his overwhelming success as an actor, writer, director and producer known for patriotic songs like "Yankee Doodle Dandy," "You're a Grand Old Flag" and "Over There."
