Heading to America after finding themselves destitute following their father's death, Charles de la Fontaine, the Marquis d'Aubeterre and his sister Helen secures a position in the home of Lathrop, a millionaire thanks to the Countess d'Este. He instantly falls in love with Lathrop's pretty daughter Marian, but she fears he is a fortune hunter and becomes engaged to the wealthy Rudolph Miller. Charles tells her he would only marry her when the two are equally wealthy. Charles then secretly backs Marian's brother Frank in a successful financial venture, making both rich. Discovering Rudolph is unfaithful and with the "golden wall" of wealth that had separated them now obliterated, Marian and Charles wed.

During the American Revolution, Alexander Hamilton and Aaron Burr are both courting beautiful Margaret Moncrieffe. Fast-forward several years and they again find themselves on opposite sides, this time about compensation for the properties of Tories--colonists who sided with the British--during the war. Hamilton falls for Maria Reynolds, who it turns out is secretly the wife of prominent pawnbroker Jacob Clingman, a friend of Burr's. The pair conspire to destroy Hamilton, who is now Secretary of the Treasury and married to the daughter of a prominent army general, by making public several love letters Hamilton had written to Mrs. Reynolds.
