End of the 17th – beginning of the 18th century. The last of the Stuarts, the Princess of Ansbach, a descendant of the Hohenzollerns, brilliantly educated and brought up, but without fortune, titles or influence, suddenly finds herself in the center of attention. A Spanish prince is vying for her hand. She can become not only a queen, but also an empress, she just needs to succumb to temptation and, seduced by the splendor of the Spanish crown, defend the Mass and accept Catholicism. But the princess does not make a deal with her conscience, and suddenly, as if as a reward, the opportunity opens up for her to become the owner of three crowns at once. She only needs to marry the Crown Prince of Prussia, and Hanover's claims to the crowns of England, Spain and Ireland become real. By beheading one king and expelling another from the country, the British created a difficult situation for themselves, because in accordance with the act of succession to the throne, if Queen Anne never had a son, the Hanoverian George Ludwig could take the vacant place of the English king.
