In New Orleans in 1869, M'su Cahusac, a charlatan of a lawyer, preys on vulnerable women, convincing each one that she is a legitimate descendant of the long-lost Dauphin, who fled Paris for New Orleans at the age of 10 during the French Revolution. Therefore, he tells each victim, she is the rightful Queen of France. Tantalized by visions of wealth, palaces and power, each victim responds in her own fashion to this preposterous revelation, which the lawyer claims is supported by the Historical Society of Paris.
