Seeking support for the Colonies' war against England, he arrives in Paris, where he enlists the aid of an old friend, Madame la Comtesse Diane de Vobrillac, a confidante to King Louis XVI.

Franklin's hopes of winning the king's support seem dashed when British forces capture Philadelphia but rally when the Colonists are victorious at Saratoga.

At home, his son William, the governor of New Jersey, sides with the enemy, and the traitorous act upsets the elder Franklin's plans.
