On Marie’s birthday, her parents use the event as an excuse to introduce Anastasia to a number of suitors. So when the handsome Count Kyros Granado meets Marie hidden away in the garden and falls in love at first sight, he believes he he has met Anastasia and writes a letter of proposal.
When Anastasia tragically dies on the way to his estate, Marie is sent to take her place—to the delight of the Count who realized he proposed to the wrong girl.
