He is a prince in the country and a member of the think tank of his mother, Ellen Claremont (Uma Thurman), the first female president of the United States. However, being a celebrity also has its disadvantages. When he and his nemesis, Prince Henry (Nicholas Galitzine) from the other side of the ocean, quarreled at the wedding dinner of Henry's brother, the photos were disclosed to the tabloids, which seriously threatened the relationship between the United States and Britain. In order to control the situation, they had to take extraordinary measures in extraordinary times: jointly forge the friendship between Alex and Henry.

When President Ellen runs for re-election, Alex finds that he and Henry have a secret love affair, which puts him in a dangerous situation. If he is not careful, it will not only jeopardize his mother's election, but also shake the relationship between the two countries again...
