In the early 20th century, King Alfonso XIII of Spain seeks a wife in England and ends up choosing Ena, Queen Victoria's granddaughter. Europe is in turmoil, and it affects Spain as well.
The young couple is very happy at first. They eagerly await the heir and their joy is immense, until it turns out that Ena has brought her own family's curse to the castle. And then war breaks out in Europe.
War ravages Europe, but Spain remains neutral. Ena finds purpose in her life by developing the Red Cross, and the king also participates in his own way, for better or for worse.
Thousands of Spanish soldiers fall in the Battle of Annual in 1921, shaking up social peace. What kind of future awaits Spain? Ena also experiences another blow to her marriage.
An era is coming to an end: the stock market crashes in New York, and de Rivera's dictatorial actions become a burden, just as Ena foresaw. The lives of the royal family are completely upended.
The royal family has been scattered across Europe. Ena has returned to London, where she gives an interview to journalist Augusto Assía. General Franco does not take this well. Will Ena's wish ever come true?
