July 1918. Preparing to speak to an eager audience, 61-year-old Teddy Roosevelt receives the telegram that all parents of children who serve in war fear most: His son Quentin's plane has been shot down in a dogfight over France. His fate is unknown. Despite rising fear for his youngest son, Teddy takes the stage to speak to his beloved fellow citizens. It is, he says, "my simple duty." But the speech evolves from politics and the war, into an examination of his life, the choices he's made, and the costs of his "Warrior Philosophy."

Overflowing with his love of nature, adventure, and justice, Teddy dramatically illustrates the life of one of America's greatest presidents. His many accomplishments ranged from charging up San Juan Hill in Cuba as commander of the Rough Riders, to facing down U.S. corporate monopolies, to launching the Great White Fleet, building the Panama Canal, and the preservation of hundreds of millions of acres of natural American beauty. And finally, to the vigorous life at Sagamore Hill and his immense pride in a beloved and rambunctious family. Teddy reveals how even the greatest of men is still just a man, and how even the most modest man can grow to be great.
