The picture shows Jeanette (Thelda Bara) becoming the mistress of the ambitious Jean du Barry (Herschel Mayall) who marries her off to one of his cousins so that she has an entree to the royal court. She soon becomes the favorite of the King (Charles Clary) and Jean du Barry becomes a regular around the court too. But all this is disturbed when Madame du Barry falls for Conte Brissac of the King's Guard (Fred Church). Jean du Barry's attempts to expose her affair only get him banished from the court.
