Spain, today. After being involved in a financial scandal, King Alfonso XIV decides to step away from the public eye. His provisional replacement as head of the Spanish Monarchy is none other than his only daughter, the irresponsible party girl, Princess Pilar. For a few months, she'll have to act as the head of the State. It's not like she's the best candidate, but she's the only one.

Guillermo, Pilar's secretary, lets her know that her best friend Camino might have compromising materials on her. The princess is incredulous because Camino and her have been friends since they were little. And so Pilar chooses to ignore his secretary's advice and invites her bestie to her first ceremony as head of the Royal Household. However, Guillermo has an ace up his sleeve.

Pilar and Guillermo work out a deal with a public university so the Princess will be awarded the title of "Distinguished Alumni". It's a delicate matter because she didn't even study there, but the goal is for Pilar to earn the favour of the public opinion. The event has been meticulously planned, but there's one thing that neither Guillermo nor Pilar had prepared for.

For the first time, Pilar will inaugurate the new judicial year. Although the event is rather bland, a surprise awaits our princess. It's become a tradition for some judges to dine with her father, the king, after the event. Pilar will be hosting this year's lunch as well, but during the meal, she will make a discovery that will completely change the way she views her father and her own life.

Richie was heir to the British Crown until one fine day he decided to relinquish his rights to the throne. He's now living as a celebrity, and this week he's traveling to Madrid to release his memoirs. Pilar and him had a passionate affair years ago that, thankfully, didn't make it into the book, but tonight they will reminisce about it, leading to a surprising revelation for our princess.

Guillermo's mother has passed away and Pilar attends the funeral in hopes of convincing Guillermo not to quit his job and to come back to the palace with her. But, in the hours before the service, the princess will come to an unexpected realization. She will discover that, for some, the monarchy still means something worthy of upholding.

Alfonso XIV has returned to Spain to record the traditional Royal Christmas Speech, in which, rather than abdicating, the King apologizes for putting his immature daughter in charge of the country. The branches of government warn Pilar that her father is out of his mind. They've tried speaking to him, but he refuses to listen. Pilar will have to convince him it's time for him to step aside.
