Alex Claremont-Diaz, the
first son of the United States, attends the wedding of Prince Phillip,
Duke of Cambridge. Alex has a long-standing feud with Prince Henry, Prince Phillip's younger brother. During the reception, Alex and Henry get into an argument that results in the £75,000 wedding cake falling on top of them. To mitigate the fallout and help his mother's re-election campaign, Alex and Henry are forced into a series of interviews and appearances, where they pose as friends. Alex later admits to Henry that he began to resent him after Henry rebuffed him at Alex's first appearance as a public figure. Henry apologizes, explaining he had just lost his father and was forced by the Palace to appear at public events while still mourning, and the two make amends, later beginning to text and become friends. Invited to Alex's annual New Year's party, a drunk Henry leaves abruptly after seeing Alex kiss several girls at midnight. Alex follows him outdoors to the
White House grounds. Henry kisses Alex, but fails to respond to Alex's attempts to contact him over the following weeks. After confiding in Nora, his best friend and the
Vice President's granddaughter, Alex realizes that he is attracted to Henry. Alex texts Henry to ask if he will be attending the Prime Minister's dinner, which Henry does not respond to. Henry eventually does come to the dinner and they share a kiss in a private room, which is interrupted by Alex's secret service. The pair become lovers, although they keep their involvement secret from everyone except close family and friends, and their
Secret Service and
MI5 bodyguards. Alex and Henry use private jets to traipse back and forth across the Atlantic throughout the film. When Alex comes up with a plan for his mother to win Texas in the upcoming election, he travels there to lead the campaign. When he goes to Brooklyn to speak at the
Democratic National Convention, Henry unexpectedly visits him. Alex later comes out to his mother, who is supportive, but advises him to think about his relationship carefully. Alex invites Henry to his family's vacation home near
Austin, Texas, and Alex begins to tell Henry that he is in love with him, but Henry, fearing that he cannot sustain a love-relationship – since the
British royal family will not accept it – preemptively leaves the conversation and flees to England. He refuses to respond to Alex's attempts to contact him. Alex visits Henry in London unexpectedly and demands an explanation for his behavior. Henry takes Alex to a museum at night, and admits that he loves Alex too, but explains that his royal position makes it difficult, and requests Alex for patience. Alex convinces Henry that their relationship is worth fighting for, and he can be as patient as required. The two reconcile. Shortly after Alex returns to the U.S., Alex and Henry's personal e‑mails to each other, and the museum's security camera footage of them embracing, are hacked and posted online, followed by wide coverage in the press. In response, Alex makes a touching speech admitting that he is in a romantic relationship with Henry. The King orders all Alex's and Henry's means of contact cut off. Zahra Bankston, the
White House Deputy Chief of Staff, gets in touch with Shaan, Henry's
equerry, and Alex and Henry are finally able to talk. Alex immediately flies to London to reunite with Henry. King James III summons them to a meeting and tells them that they cannot be together, since their relationship is incompatible with royal tradition and the expectations of the public. However, Henry's supportive sister Beatrice notices a crowd gathered in front of
Buckingham Palace in support of them, and she cites news reports of similar crowds all over the U.K. Alex and Henry kiss in front of the window, then step outside together onto the balcony and openly greet the cheering public as a couple. On election night, Henry returns to the United States to be with Alex, whose plan to win Texas for his mother ultimately results in her barely winning re-election. Later that evening, Alex and Henry are seen biking down the street toward Alex's "working class" childhood home in Austin, where they leave the bikes on the lawn and go inside to personally celebrate. == Cast ==
