In this adaptation of Casey McQuiston’s novel, we follow Alex Claremont-Diaz, the first son of the US president. He’s the closest thing to a west-Atlantic prince. With her intrepid sister and Veep’s genius granddaughter, they form the White House Trio, a beautiful millennial marketing ploy for her mother, President Ellen Claremont. International socialite duties do have downsides – namely when photos of a confrontation with her old nemesis Prince Henry at a royal wedding leak to the tabloids and threaten American/British relations. The plan for damage control: stage a fake friendship between the First Son and the Prince. As President Claremont begins her re-election bid, Alex finds himself embroiled in a secret relationship with Henry that could derail the campaign and topple two nations.
