Alex is the First Son. Henry is the Prince of Wales. The two have had an ongoing secret rivalry for years, but then at a public engagement, their disdain causes a diplomatic incident that threatens the bond between the two nations. Going into damage-control mode, their families and handlers force the two rivals into a staged "truce." Nevertheless, the fake relationship turns into something deeper than they ever expected. But they are still the First Son and the royal prince. Based on Casey McQuiston's critically acclaimed New York Times best-seller, with a dash of youthful spirit, and an enchanting love story, comes the refreshing film adaptation that is just what you need for the hot summer days.
